Heat and mass mixed convection for MHD visco-elastic fluid past a stretching sheet with ohmic dissipation

摘要: Abstract In this study, an analysis has performed for heat and mass transfer of a steady laminar boundary-layer flow electrically magnetic conducting fluid second-grade subject to suction transverse uniform electric field past semi-infinite stretching sheet. Parameters Gr , Gc E 1 M Sc which are used represent the dominance buoyant effect, effect present in governing equations, respectively. The novelty work is considered phenomena coupled equations. similar transformation finite-difference method analyze problem. numerical solutions velocity distributions, temperature profiles, wall unknown values θ ′ ( 0 ) ϕ calculating carried out as functions visco-elastic parameter E, Prandtl number Pr, buoyancy parameters coefficient Sc. value Pr important factors study. It will produce greater efficiency with larger those parameters, but may reduce efficiency. On other hand, transfer, factor
