Semi-Analytical Solution of Natural Convection Flow of Non-Newtonian Fluid With Temperature-Dependent Viscosity In Pipe

Abstract

Abstract: This paper presents semi-analytical solution of natural convection flow of non-newtonian fluid with temperaturedependent viscosity in pipe. The governing equations were solved using perturbation technique. The results obtained were analyzed for various thermo-solutal parameters involved in the dimensionless equations. Results within the constant viscosity show that increase in these parameters increases the velocity of the fluid flow as well as the temperature of the cylindrical pipe. It is observed that increase in the Reynold’s viscosity indices increases the temperature of the cylindrical pipe greatly.
