✦ Synopsis

The role of surface resistance in the formulation of the penetration theory of interphase transfer is examined for the cases of constant, uniform surface renewal rate and random surface renewal using the distribution function proposed by Danckwerts;

it is shown that both cases are almost equivalent. Some recent data obtained in experiments aimed at measuring the condensation coefficient of water are examined in light of the penetration theory formulated with and without surface resistance. It is shown that the data suggest a transition from the conventional penetration theory (without surface resistance) to a regime where surface resistance becomes important and begins to control the transport rate. It is also pointed out that the data may suffer from fluid mechanical acceleration effects and that they also suggest a condensation coefficient which decreases with time.
