Dissertation/Thesis Abstract

Analysis of Heat Transfer through Porous Perlite with Varying Pore Size and Moisture Content
by Javid, Faisal, M.S., Southern Illinois University at Edwardsville, 2015, 72; 1591165
Abstract (Summary)

Flow through a porous media has always been a byzantine analysis to solve, since porosity is not a property of the medium in its conventional sense, unlike density, thermal conductivity or electric resistivity etc. Porosity depends on innumerable conditions that prevailed when the material was being formed. These conditions include but are not limited to temperature, pore size, moisture content etc. This project models the flow of an incompressible fluid (water) through a porous medium (perlite) for a definite value of porosity and permeability. A code has been written in MATLAB to obtain the temperature distribution within the porous medium along the thickness of the sample and the same is plotted. Modified versions of the governing equations of mass, momentum and energy were simplified with valid assumptions and solved using iterative methods.

The code can be modified for different values of porosity and permeability and also for different materials. The results obtained from this code are approximate but are accurate enough to model the heat transfer through the porous media to an agreeable level. Results were also obtained using the ANSYS FLUENT, and it was found out that there was an average error of approximately 1% for both dry perlite and 100% fully saturated perlite when compared to theoretical results.
