✦ Synopsis

An experimental technique which utilized a Mach-Zehnder interferometer was used to measure local heat and mass transfer coefficients during simultaneous heat and mass transfer. The experimental model was a vertical, subliming surface of p-dichlorobenzene. The body force created by the heavy organic vopor in the boundary layer opposed the upward thermal body force caused by heating the surface. The results indicated that the heat and mass transfer, under the influence of opposing body forces over the range investigated, was from 10 to 15% lower than the values predicted by present approximate analytical solutions for a constant wall heat flux boundary condition.
