Theoretical analysis of evaporation and vapor flow between two parallel planes
Abstract
Pressure, temperature and velocity distributions were computed for vapor flow originating by the evaporation from one surface of a space bounded by parallel planes. A finite difference method was employed using dimensionless parameters with the inclusion of a generalized expression for the saturation temperaturepressure relation of selected fluids. Results indicate that the ordinarily neglected dissipation and volume work functions should not be omitted from the energy equation and that a simplified method using an adiabatic pressure gradient expression for estimating temperature changes gives erroneous results.
