An experimental method for measuring mass transfer rates at high mass fluxes is developed for the case of evaporation at the stagnation point of a cylinder. Evaporation of carbon tetrachloride at the stagnation point was measured and determined to be consistent with theoretical predictions. It was observed that water exhibits a significant interfacial resistance to evaporation at high transfer rates. Evaporation coefficients based on the discrepancy between experimental determinations and theoretical expectations were found to be a strong function of temperature and to be consistent with the majority of reported measurements made at lower temperatures. The experimental method should be useful for application to other configurations and flow conditions for studying mass transfer at high mass fluxes.
