【 摘 要 】

References(7)Cited-By(6)A mathematical model of heat and mass transfer on the rotating evaporator surface in a centrifugal molecular still is developed. The solutions of surface temperature profile, rate of evaporation and liquid film thickness for liquid of Pr < 100 are obtained in the case where the temperature of liquid on the rotating evaporator surface varies with evaporation. These solutions in the limited case of constant surface temperature agree with those of Greenberg. The dry-out position of liquid on the rotating evaporator surface can be estimated from the present model.
