摘要：

A magnetic hydrodynamic (MHD) mixed convective heat transfer problem of a second-grade viscoelastic fluid past a wedge with porous suction or injection has been studied Governing equations include continuity equation momentum equation and energy equation of the fluid It has been analyzed by a combination of a series expansion method the similarity transformation and a second-order accurate finite-difference method Solutions of wedge flow on the wedge surface have been obtained by a generalized Falkner-Skan flow derivation Some important parameters hive been discussed by this study which include the Prandtl number (Pr) the elastic number (E) the free convection parameter (G) and the magnetic parameter (M) the porous suction and injection parameter (C) and the wedge shape factor (beta) Results indicated that elastic effect (E) in the flow could increase the local heat transfer coefficient and enhance the heat transfer of a wedge In addition similar to the results from Newtonian fluid flow and conduction analysis of a wedge better heat transfer is obtained with a larger G and Pr (C) 2010 Elsevier Ltd All rights reserved
