    Abstract: 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 mod... Show More

    Abstract: 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 deman...

    Abstract: 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... Show More

    Abstract: 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... Show More
