Boundary Layer Flow and Heat Transfer of Casson Fluid Over a Porous Linear Stretching Sheet with Variable Wall Temperature and Radiation

摘要

A flow and heat transfer analysis is carried on non-Newtonian Casson fluid through the thermal boundary layer over previous linear stretching membrane with variable wall temperature and radiation. The governing equations for the present problem are deformed into nonlinear ordinary differential equations with the aid of similarity transformations. A regular perturbation method is applied to determine the solution for the energy equation. The variations of Prandtl number, Casson fluid parameter, suction parameter, and fluid thermal radiation parameter on temperature and velocity profile are discussed through graphs.
