Science Publishing Group: International Journal of Fluid Mechanics & Thermal Sciences: Table of Contents
<i>International Journal of Fluid Mechanics & Thermal Sciences (IJFMTS)</i> will be a forum for the publication of high-quality peer-reviewed papers on fluid mechanics and thermal sciences. This journal also publishes contributions that employ existing experimental techniques to gain an understanding of the underlying discipline. In fact, fluid mechanics and thermal sciences applications are ubiquitous in nature. Many aspects in industrial operations and daily life are closely related to fluid flow and heat transfer processes. Along with the development of computer industry and the advancement of numerical methods, solid foundation in both hardware and software has been established to study the processes by using numerical simulation methods, which play important roles in the ways of extending research topics, reducing research costs, discovering new phenomena, and developing new technologies. Methods for solving ancillary equations such as transport and diffusion are also quite relevant. The expressed intention of this journal is the dissemination of information relating to the development refinement and application of numerical and experimental techniques for solving problems in fluid mechanics and thermal sciences.

Time Step Size Effect on the Liquid Sloshing Phenomena
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150101.12
In this paper, the effect of the time step size on the numerical results of the liquid sloshing problem was studied for a laterally moving three-dimensional (3D) rectangular tank in a battery cell. The commercial software "Fluent" has been used to predict the local flow characteristics in the tank. To simulate 3D incompressible viscous two phase ﬂow in a tank, partially ﬁlled with liquid, the volume of ﬂuid (VOF) method based on the ﬁnite volume method has been considered. The comparison between numerical and experimental results confirms the validity of the numerical method.

http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150101.11
The present paper is dedicated to the numerical simulation of the height effect of an inclined roof obstacle. The governing equations of mass and momentum in conjunction with the standard k-ε turbulence model are solved using the computational fluid Dynamics (CFD). The numerical method used a finite volume discretization. Experiments in wind tunnel are also developed to measure the average velocity near two inclined roof obstacles. The numerical simulations agreed reasonably with the experimental results and the numerical model was validated.

Evaluation of the Savonius Wind Rotor Performance for Different External Overlap Ratios
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150101.13
Experimental investigations were carried out to study the external overlap ratios effect on the performance of a vertical axis wind rotor of the Savonius type. For thus, an open wind tunnel has been designed and realized in Laboratory of Electro-Mechanic Systems at National School of Engineers of Sfax. This involved also the instrumentation and the necessary equipment for the global characterization of the Savonius wind rotor. Particularly, this research required the setting up of four mounting characterized by different external overlap ratios. The overall performance evaluation of the rotor has been based on the power and dynamic torque coefficients in function of the air velocity speed measured in the test vein of the wind tunnel.

Study of the Computational Domain Effect on the Aerodynamic Structure Around a Savonius Wind Rotor
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150102.11
This study aims to investigate the effect of the computational domain on aerodynamic characteristics of the flow around a Savonius wind rotor. For thus, we have developed a numerical simulation using CFD code. The considered numerical model is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-ε turbulence model. These equations were solved by a finite volume discretization method. Particularly, we are interested to visualize the velocity field, the mean velocity and the static pressure. The good comparison of our numerical results with anterior results confirms the validity of the numerical method.

An Experimental Investigation on Addition of Bentonite on Tannery Wastewater Characteristics
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150102.12
In this study, wastewater generated from Africa tannery in Khartoum North was investigated for removing of chromium from a wastewater by utilizing Bentonite. Experiments were carried out in order to obtain the optimum dose of Bentonite to be applied for the best removal of chromium and other wastewater parameters which include chemical oxygen demand, Oil and grease, total suspended solid, and chloride. For a 15mg/L dose of Bentonite removal rates of 99%, 44%, 94%, 75% and 53% of chromium(Cr), chemical oxygen demand (C.O.D), total suspended solid (T.S.S) and chloride (Cl) were respectively obtained. The Removal time for the above dose 15 mg/L was 6 hours. The results of the test were statistically analyzed by regression technique and a predication model was obtained after three trends of testing (linear, Exponential and polynomial). The exponential trend was the best (R2=0.9368). The prediction model was validated by comparing predicted and measured data and good fit of data were obtained. Therefore, the use of Bentonite to remove chromium is considered as a very successful method, and it can be a solution to the problem of industrial waste resulting from the tanning industry.

Numerical Investigation of Nucleate Boiling Flow in Water Based Bubble Bumps
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150102.14
In this paper, numerical simulations of nucleate boiling flow bubble pumps are conducted with the commercial CFD (Computational Fluid Dynamics) package ANSYS-FLUENT. The Eulerian multiphase flow framework model was used to model the phase’s interaction. User-Defined Functions (UDFs) are provided to compute the wall heat transfer and to calculate in-ter-phase heat and mass transfer. The heat flux from the wall is divided into three parts according to a wall heat partitioning model based on three mechanisms including convective heat for heating the bulk liquid, evaporative heat for generating vapor and quench heat for heating the liquid in the nucleation sites. The rate of vapor formation is obtained by adding the mass exchange at the bubble surface and the bubble formation due to heat flux at the wall. Constant heat fluxes are applied to the stainless-steel made tube wall. In the simulation results we discuss the radial temperature distribution and the radial and axial profiles of the vapor void fraction in the pipe to localize the onset of vapor generation in the pump tube.

http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150102.13
Two-dimensional steady-state buoyancy driven flows of thermo-dependent shear-thinning power-law fluid confined in a square cavity, submitted to cross uniform heat fluxes, has been conducted numerically using a finite difference technique. The parameters governing the problem are the thermo-dependence number m (0≤m≤10) and the ratio between the heat flux imposed on the vertical walls and that imposed on the horizontal ones represented by a (0≤a≤1), while the flow behavior index n is fixed at (n=1.4) and the Rayleigh number at (R_a=5000). The effects of these parameters on the flow structure and heat transfer characteristics have been analyzed.

PIV Study of the Interrogation Area Size Effect on the Hydrodynamic Results of a Stirred Vessel Equipped by an Eight Flat Blades Turbine
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150103.11
The aim of this paper is to investigate the interrogation area size effect on the hydrodynamic results of a stirred vessel equipped with an eight flat blades turbine. Particle image velocimitry (PIV) technique was used in order to compute the velocity field in the vessel. This PIV system is equipped with a Nd:YAG 532 nm laser, a CCD camera and a mini synchronizer. In this study, it has been observed that the interrogation area size has a direct effect on the results efficiency. According to the achieved results, for a grid size between 12x12 pixel² and 128x128 pixel², it has been observed that the parameters selection has a great influence on the experimental results. Particularly, it has been noted that the maximum areas size increases by increasing the interrogation area size.

Thermodynamic Study of the Active Magnetic Regenerative Refrigeration in Transitional Regime
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150103.12
Magnetic refrigeration is an emerging technology based on the magnetocaloric effect. In this paper, the magnetocaloric effect is remembered. The components of magnetic refrigeration system are described. An analogy between magnetic refrigeration and conventional refrigeration is done concerning the steps and the original work received by the system. A regenerator positioned between the hot source and the cold source increases the efficiency of the refrigeration system, from which the active magnetic regenerative refrigeration (AMRR) is studied. Thus a thermodynamic study is developed and thermal regenerator study transitional regime is done. From the results obtained by the numerical calculation, the difference of temperature between hot and cold sides reaches a limit after a certain number of cycles. This number of cycles (Nc) necessary to wait for the permanent regime depends on the difference in temperature hot side and cold side (∆T), the flow regime and the magnetocaloric effect (MCE) of the regenerator. Moreover this work allowed us to study the thermal and fluidic behavior of the magnetic regenerative refrigeration, as well as to determine the flux exchanged during magnetization and demagnetization.

Fluid Dynamic Study of a NACA2415 Airfoil Type Wind Turbine with a Wedging Angle Equal to 30°
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150103.13
In this paper, numerical simulations and experimental validation were carried out to gain an insight into the complex flow field developing around a small wind rotor and to evaluate its performance. We consider the Navier-Stokes equations in conjunction with the standard k-ε turbulence model to study the aerodynamic parameters of a NACA2415 airfoil type wind turbine. These equations are solved numerically to determine the local characteristics of the flow and the models tested are implemented using the open source "SolidWorks Flow Simulation".Experiments have been also conducted on an open wind tunnel equipped by a small NACA2415 airfoil type wind turbine to validate the numerical results. This will help improving the aerodynamic efficiency in the design of packaged installations of the NACA2415 airfoil type wind turbine.

Performance of a Typical Simple Gas Turbine Unit under Saudi Weather Conditions
http://www.sciencepublishinggroup.com/journal/paperinfo.aspx?journalid=315&doi=10.11648/j.ijfmts.20150103.14
Gas turbine units are widely used in KSA and other countries particularly during the peak demands and in inland regions. They produce about 50% of the total capacity of power generation in the kingdom. Despite their numerous advantages, their thermal efficiency remains very low and their resulting environmental impacts are significant. In this study, the effect of ambient conditions on the performance of a typical gas turbine used in KSA has been studied theoretically using the average hourly temperature and relative humidity for three regions of the country (Eastern, Central, and Western) which have almost the same power demand. Mass and energy balance equations with typical and realistic specifications of power plant units have been used to develop the model. The results present time variations of power generation, fuel consumption and efficiency for several typical cities. The maximum monthly power loss due to weather variation in Riyadh, Ad Dammam, and Jeddah are estimated at 8.9, 9.41 and 9.32 GWh respectively. While the annual power production loss in Riyadh, Ad Dammam, and Jeddah are 7.1, 8.2, and 11.2%, respectively. Power generation increases to about 4220 and 3028 kW when inlet air is cooled to 8.9 and 10.15oC, respectively. In conclusion, the effect of weather conditions of several Saudi areas on the performance of gas turbine units is significant. Therefore, the incorporation of inlet cooling technologies should be considered seriously.
