Abstract

Abstract

Bubble mean diameter is a key parameter to calculate the interfacial transfer equation of two phase flow and interfacial concentration.Taking into account the effects of both the thermal,hydrodynamic conditions and bubble coalescence rate on the mean bubble size in the channel,a model has been developed.The proposed model agreed well with the experimental data within the averaged relative deviation of ±12.5%.

- Bubble coalescence,
