Abstract
This study deals the investigation of heat transfer of non-Newtonian fluid in the presence of a porous bounding wall. Perturbation method is applied for the solution of non-linear differential equation. The main focus of this paper is to investigate the effects of parameters such as Reynolds number Re, Prandtl number Pr, permeability parameter K and n in the velocity of fluid and temperature coefficient. For fulfilling the purpose Matlab software has been used. The results show that velocity of non-Newtonian increases with increase of Reynolds number Re and temperature increases with increases of Prandtl number Pr.
Highlights
The non-Newtonian fluid flow through a porous medium produced by temperature differences is one of the most considerable and contemporary subjects and found the great applications, in geothermic, geophysics, chemicals, cosmetics, pharmaceuticals and industrial technology
The objective of the present study is to find out the solution of heat transfer of non-Newtonian fluid in the presence of a porous bounding wall, for the purpose we have used the perturbation technique
It is seen that increase of Reynolds number Re velocity of fluid increases sharply
Summary
The non-Newtonian fluid flow through a porous medium produced by temperature differences is one of the most considerable and contemporary subjects and found the great applications, in geothermic, geophysics, chemicals, cosmetics, pharmaceuticals and industrial technology. The practical interest in convective heat transfer in porous medium is expanded rapidly, due to the wide range of applications in engineering fields. Blottner (1970) has studied finite-difference methods of solution of the boundary-layer equations. Chamkha (1977) has studied similarity solution for thermal boundary layer on a stretched surface of a non-Newtonian fluid. Dharmadhikari and Kale (1985) have studied flow of non-Newtonian fluids through porous media. Chen and Chen (1988) have studied free convection of nonNewtonian fluids along a vertical plate embedded in a porous medium. Wang Chaoyang and Tu Chuanjing (1989) have studied boundary-layer flow and heat transfer of non-Newtonian fluids in
