Summary
Anisotropy is the result of optional orientation or geometric asymmetry caused by the position of particles in an object. The fully developed laminar steady forced convection inside a circular tube filled with saturated porous medium with uniform heat flux at the wall was studied by Hooman and Ranjbar-Kani They described that the velocity profile depended strongly on s paramete r ( S (1 / (M Da))1/2 , where M is viscosity ratio, and Da is the Darcy number). This paper presents an analytical study of steady force convection heat transfer inside an anisotropic porous cylinder with oblique principal axes, using the extended Darcy-Brinkman model with the aim of investigating the effects of aniso tropic permeability. The anisotropy of the porous medium is characterized by the orientation angle θ and the permeability ratio parameter K*= K1/ K2 Other assumptions for this model are as follows: fluid flow is one-dimensional and fully developed, steady state conditions, no phase changes, constant heat flux is applied to horizontal walls, and uniform heat generation exists in the cylinder. For the left side of Eq [17] from definition of the average temperature, it would be: rVzTdr R rVzT dr 0R rVz dr rVz dr 0
