Effects of Viscous Dissipation and Double Stratification on MHD Casson Fluid Flow over a Surface with Variable Thickness: Boundary Layer Analysis

摘要: In this article, the motion of two-dimensional Casson fluid flows with temperature dependent plastic dynamic viscosity together double (i.e. thermal and solutal) stratification in presence Lorentz force is investigated. The case where tends to take energy away from (kinetic energy) transform it into internal considered. nonlinear governing equations their associated boundary conditions are transformed non-dimensionalized using similarity variables which thereafter solved numerically shooting method Runge-Kutta technique. effects magnetic field parameter, Eckert number, velocity power index, pressure gradient parameter wall thickness on velocity, temperature, concentration profiles showed graphically discussed. Substantial increase distribution certain an magnitude number. Local skin friction coefficient decreases parameter.
