Abstract
The aim of the present analysis is to investigate the effects of variable viscosity on MHD Carreau nanofluid flow along a nonlinear stretching surface in the presence of thermal stratified medium. Generalized Fourier’s and Fick’s laws are used in order to examine the heat and mass transport phenomena. Near the surface of the plate mass flux is assumed to be zero. The governing boundary layer equations are modeled and renovated into nonlinear ODE’s by using similarity transformation, and numerical solution is calculated via shooting method (coefficient upgraded by Cash and Carp). Plots and tables representing friction factor, velocity distribution, temperature and concentration distributions are discussed. Conclusions are made on the basis of entire examinations, and it is found that the velocity profile enhanced for enhancing values of Weissenberg number and thermal buoyancy parameter, while thermal buoyancy shows opposite behavior for temperature distribution. Moreover, concentration profile diminishes for enhancing values of solutal stratification parameter and concentration buoyancy parameter.
