Direct contact heat transfer during evaporation of immiscible liquid mixtures.

Type of article: Article, IJR article

Summary

A study of the heat transfer between a boiling refrigerant in direct contact with hot water was made, the two fluids being immiscible. The refrigerant and water were mixed in an injector, boiling taking place in a vertical tube. The location of the point where boiling terminated was determined at various system conditions. Volumetric heat transfer coefficients in the system can be up to 40 times higher than those for conventional systems. In order to illustrate system phenomena, a simple model was developed taking into account the heat transfer around a small droplet of refrigerant. The theoretical results agree with experimental values.
