Taylor-Couette flows in a horizontal annular gap between finite coaxial cylinders rotor-stator configuration are numerically investigated. The inner cylinder (rotor) rotates at constant angular velocity while the outer (stator) is rest. They limited their extremities by two fixed walls that prevent axial fluid-flow. In addition, heat transfer generated an imposed temperature difference, with ro...

An analytical study is performed to investigate the effects of chemical reaction and radiation on unsteady MHD flow past an exponentially accelerated vertical plate with variable temperature and variable mass diffusion in the presence of applied transverse magnetic field. It is assumed that the effect of viscous dissipation is negligible in the energy equation and there is a first order chemica...

The influence of an external oriented magnetic field on entropy generation in natural convection for air and liquid gallium is numerically studied in steady-unsteady states by solving the mass, the momentum and the energy conservation equations. Entropy generation depends on five parameters which are: the Prandtl number, the irreversibility coefficients, the inclination angle of the magnetic fi...
