Magnetohydrodynamic Boundary Layer Flow of a Viscoelastic Fluid Past a Nonlinear Stretching Sheet in the Presence of Viscous Dissipation Effect

摘要: This paper numerically investigates the viscous dissipation effect on boundary layer flow of an electrically-conducting viscoelastic fluid (Walter’s B liquid) past a nonlinear stretching sheet. The partial differential equations governing problem are transformed into ordinary through similarity variables. then solved using Keller box method. A careful evaluation influence pertinent parameters velocity field and temperature distributions various plots is done for prescribed surface (PST) heat flux (PHF) conditions. computed coefficient skin friction, rate transfer (Nusselt number), at wall also presented in tabular form. It revealed from this table that magnitude reduced with increase Eckert number E c , parameter K, magnetic M PST case by about 12%, 20%, 29%, respectively. Similarly, PHF decreases 8% 24%, obvious application condition excels keeping warmer than condition. implies applying better cooling sheet faster. unchanged changes case, it ascertained present results close agreement previous published results.
