Abstract

Moving boundary problems with mass and heat transfer are discussed and an apparent thermaf conductivity ke'' is proposed to represent the effect of the sensible heat of the diffusing gas on the moving rate of the boundary. Although this effect is usually small, it should be taken into account for some cases when the drying of wet porous bodies or the thermal decomposition of solids is conducted at a high ambient temperature.
