{"title":"Conjugate Heat and Mass Transfer for MHD Mixed Convection with Viscous Dissipation and Radiation Effect for Viscoelastic Fluid past a Stretching Sheet","authors":"Kai-Long Hsiao, BorMing Lee","volume":38,"journal":"International Journal of Mechanical and Mechatronics Engineering","pagesStart":144,"pagesEnd":152,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/15267","abstract":"In this study, an analysis has been performed for\r\nconjugate heat and mass transfer of a steady laminar boundary-layer\r\nmixed convection of magnetic hydrodynamic (MHD) flow with\r\nradiation effect of second grade subject to suction past a stretching\r\nsheet. Parameters E Nr, Gr, Gc, Ec and Sc represent the dominance of\r\nthe viscoelastic fluid heat and mass transfer effect which have\r\npresented in governing equations, respectively. The similar\r\ntransformation and the finite-difference method have been used to\r\nanalyze the present problem. The conjugate heat and mass transfer\r\nresults show that the non-Newtonian viscoelastic fluid has a better heat\r\ntransfer effect than the Newtonian fluid. The free convection with a\r\nlarger r G or c G has a good heat transfer effect better than a smaller\r\nr G or c G , and the radiative convection has a good heat transfer\r\neffect better than non-radiative convection.","references":"[1] J.P.
