STUDIES ON CONVECTIVE HEAT TRANSFER IN POROUS MEDIA

Abstract

A porous medium is a material containing pores (voids). The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid (liquid or gas). Natural porous materials such as rocks and soil , biological tissues bones, wood, and syanthice materials such as cements and ceramics can be considered as porous media. The concept of porous media is used in many areas of applied science and engineering: filtration, mechanics geomechanics, soil mechanics, rock mechanics, petroleum engineering, bio-remediation, construction engineering , material science. The convection heat transfer of air by heating plate was investigated experimentally. Porous media intensify fluid flow mixing and increase the surface area in contact with the coolant, so porous structures are an effective heat transfer to greater increase technique. Type of porous media natural and synathice and fluid properties on the convection heat transfer and heat transfer increase were investigated. The results showed that the convection heat transfer in the synathice porous media was more intense than in the natural porous media. For the tested conditions, the heat transfer in the syanthice porous media was more than the natural porous media for air.The pressures drop were decrease with respect to time in the natural porous media and the syanthice porous media for air. The temperatures were increased with respect to time in the natural porous media and the syanthice porous media for air.
