Contributions of variable viscosity and thermal conductivity on the dynamics of non-Newtonian nanofluids flow past an accelerating vertical plate

Abstract

The present study is focused on the contributions of variable viscosity and thermal conductivity on the dynamics of non-Newtonian nanofluids flow with nonlinear buoyancy force. A constant magnetic field is applied transversely to the flow direction. The nonlinear couples partial differential equations (PDEs) and the boundary conditions were reduced into system of ordinary differential equations by using appropriate transformation. The transformed equations were solved by utilizing spectral homotopy analysis method (SHAM) and spectral relaxation method (SRM). A higher value of Casson parameter was noticed to decrease the velocity profile. The outcome of this paper was compared with previously published works and was in good agreement.
