Chebyshev finite difference method for the effect of variable viscosity on magneto-micropolar fluid flow with radiation

Abstract

An analysis is presented for heat transfer to MHD flow of a micropolar fluid from an isothermal stretching sheet with suction through a porous medium in the presence of radiation and variable viscosity. The fluid viscosity is assumed to vary as an inverse linear function of temperature. The governing fundamental equations on the assumption of small magnetic Reynolds number are approximated by a system of nonlinear ordinary differential equations and are solved numerically by using Chebyshev finite difference method (ChFD). Numerical soluations are obtained for different values of radiation, variable viscosity, magnetic and porous parameters
