An investigation into the heat and mass transfer of a liquid evaporating from a capillary-porous body

A theoretical analysis is presented for the process of heat and mass transfer in the case of a liquid evaporating from a capillary-porous body into an approaching gas stream. The method of the experimental investigation into this process is described. The excellent agreement between the experimental and theoretical data makes it possible to use the resulting quantitative relationships to calculate the heattransfer coefficients in the case of intermittent cooling.
