Abstract
Local evaporation rates were measured from strips of saturated surfaces imbedded in wavy surfaces. Mean water vapor concentrations and mean velocity distributions were also measured over the wavy boundary. In the region far downstream of the leading wave, where the equilibrium boundary layer conditions were achieved, the average mass transfer coefficient was found to be a simple a power function of the surface Reynolds number. Based on this result, the mass transfer data from this study correlated well with the mass transfer data from surfaces of various other geometries, e.g., evaporation data from water waves, evaporation data from flat plate and sublimation data from surfaces roughened with irregular pyramids and spanwise humps.
