概要

• 論文の詳細を見る

• Heat transfer by natural convection in a vertical porous layer with horizontal heat flow has been studied analytically and experimentally. A boundary-layer analysis is extended to take account of both the vertical temperature gradient in the core of the porous layer and the apparent wall-film thermal resistance which is caused by a local increase in porosity in the vicinity of the wall. Comparison with experiment by use of porous layers composed of glass beads and water is afforded by overall heat-transfer coefficients and temperature distributions. Simple analytical expressions are obtained for the effect of the wall-film thermal resistance.
