Abstract:Heat transfer in unsteady MHD channel flow (of an incompressible viscous and electrically conducting fluid) under oscillatory pressure gradient when the channel surfaces are conducting and moving with time-dependent velocities has been analysed. The velocity, magnetic field and temperature distributions have been obtained and their numerical results are shown graphically.Symbols u velocity - H o applied magnetic field - H x induced magnetic field - T temperature - T 1 * ,T 2 * temperatures of the upper and lower planes - rgr density - p pressure - ngr kinematic viscosity - eegr magnetic diffusivity - sgr electrical conductivity of the fluid - A * characteristic velocity - L characteristic length - mgr e magnetic permeability of the fluid - C p specific heat - mgr coefficient of viscosity - k thermal conductivity - mgr 1,mgr 2 permeabilities of the planes - sgr 1,sgr 2 conductivities of the planes - PHgr 1,PHgr 2 conductance ratios of the planes - Pr Prandtl number (=ngrrgrC p /k) - E Eckert number
