Abstract: 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.

Abstract: 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.
