Abstract

This paper investigates the flow and heat transfer qualities in a Casson liquid over a porous vertical heated stretching surface with transpiration within the sight of variable liquid properties. The nonlinear governing equations with appropriate boundary conditions are at first cast into dimensionless by using similarity transformations and then the subsequent conditions are settled by means of ideal homotopy investigation strategy (OHAM). The impacts of fluid viscosity, Casson parameter, convection parameter, velocity exponent parameter, variable thermal conductivity parameter, and the transpiration parameter on flow and temperature fields are analyzed graphically. The examination uncovers a significant impact of transpiration (divider suction or infusion) on the flow and heat transfer qualities.
