Partial Heating at Lower Section of Annulus Subjected to Conjugate Heat Transfer in Porous Annulus

摘要

This study is undertaken to investigate the effect of segmental heating on the porous annulus having embedded with two solid walls at two radii. The heat transfer from hot surface to cold surface is analyzed with respect to half of the annulus being heated at inner radius and outer radius subjected to cooling temperature. The appropriate governing equations are solved numerically using finite element method. It is found that the thermal conductivity ratio of two solids being implanted on annulus plays a vital role in determining the heat transfer behavior of whole domain.
