Numerical Study of Dependent Viscosity and Dependent Thermal Conductivity on a Natural Convection Flow over a Sphere in Presence of Heat Generation

Abstract

The objective of this research is to investigate the conjugate effects of dependent viscosity and dependent thermal conductivity on natural convection flow of an electrically conducting fluid over an isothermal sphere with heat generation. Viscosity is considered to be variation and also thermal conductivity is taken as a linear function of temperature. The governing equations are solved numerically by numerical solution strategy as per requirement and suitability. Solution method such as finite difference method with keller box scheme has been employed. The computational findings for dimensionless velocity profiles, temperature profiles, local skin friction coefficient and local heat transfer coefficient are displayed graphically.
