摘要：
In view of the beneficial effect on the heat transfer in tubular heat exchangers of arranging for film flow of boiling liquid ammonia, an experimental study has been set up to obtain data on this effect. This study showed that the heat transfer rate is augmented by reducing the film thickness. The study also produced a semiempirical formula, which is recommended for design purposes in constructing ammonia evaporators utilizing a liquid-ammonia film.
