Abstract:
In this article temperature distribution calculation in a porous media is considered. A tube filled with porous substance was examined by two different models. The first model is an easy one and the second one can be used successively, to get better results. This question was a combined heat transfer and fluid dynamics. In order to determine the flow rates in the channels of the second model Bernouli and continuity equation was combined. Numerical analysis using Gauss Seidel iteration and finite difference model was used to determine the temperature distribution. Two different mode of convection was examined as forced and mixed convection. The results are in the form of different graphs and figures. These results was tried to be checked by an experimental correlation and also a theoretical correlation found in the literature. These showed that the previous expectation that the second model is closer to porous media behavior was a right guess.
