Abstract
The objective of this work is to evaluate a mathematical model of heat and mass transfer through a sand layer under constant meteorological conditions. The mathematical models of evaporation in sand under the temperature gradient are compared with experimental results of temperature profile, vapor pressure profile and evaporation flux density. The computed results agree with the experimental results for all tests.
It is found that if arbitrary meteorological conditions and moisture content profile are given, the only set of evaporation flux density and temperature profile can be decided in the thermodynamically equilibrium condition.
