✦ Synopsis

Exact solution of the convective dlffusron equation for the case of dlssolutlon of a solld wall Into a faihng lammar hqmd film 1s obtamed m terms of confluent hypergeometrlc functions By the aid of this soluhon the apphcabtity of the concentration boundary layer theory 1s checked and the accuracy of some approximate solutions 1s estimated Experunental data for the chssolutlon of gypsum mto water under the condltlons of a wavy tilm flow m&ate that waves cause a slight effect on the mass transfer rate within a wide range of Reynolds numbers
