Notes:
An approach has been developed for predicting rates of interphase mass transfer under conditions of high flux and high concentration level. A rectangular channel device has been used to measure rates of evaporation of four solutes, carbon disulfide, n-pentane, cyclopentane, and ethyl ether, from n-tridecane into flowing nitrogen. The evaporation rate of carbon disulfide agreed with the prediction of the interphase theory up to a carbon disulfide mole fraction of 0.30 in the bulk liquid. For the other three systems, a concentration gradient induced, surface tension driven cellular convection served to increase liquid-phase coefficients substantially. A correlation was obtained for the effect of this cellular motion on the liquid-phase mass transfer coefficient.
