| 要約: | The analysis of magnetohydrodynamic mixed convection boundary layer flow over a permeable stretching wedge in the presence of heat generation, viscous dissipation, thermal radiation and ohmic heating has been presented. The governing equations are nondimensionlised using the similarity transformations and the resulting coupled non-linear ordinary differential equations have been solved by using the Homotopy Analysis Method (HAM). The effects of pertinent parameters such as magnetic field parameter, velocity ratio parameter, radiation parameter, heat generation/absorption parameter and Eckert number on the velocity and temperature fields are presented. It is found that the momentum and thermal boundary layer thicknesses decrease with the increase of Eckert number in the presence of suction and heat absorption when the wedge stretches slower than the free stream flow. The present results for skin-friction are compared with the previously published results for the limiting case and an excellent agreement is found between the results.
