摘要：The main concern of the present paper is to study the MHD mixed convective heat transfer for an incompressible, laminar, and electrically conducting viscoelastic fluid flow past a permeable wedge with thermal radiation via a semianalytical/numerical method, called Homotopy Analysis Method (HAM). The boundary-layer governing partial differential equations (PDEs) are transformed into highly nonlinear coupled ordinary differential equations (ODEs) consisting of the momentum and energy equations using similarity solution. The current HAM solution demonstrates very good agreement with previously published studies for some special cases. The effects of different physical flow parameters such as wedge angle (β), magnetic field (M), viscoelastic (k1), suction/injection (fw), thermal radiation (Nr), and Prandtl number (Pr) on the fluid velocity component (f′(η)) and temperature distribution (θ(η)) are illustrated graphically and discussed in detail.
