Flow boiling enhancement of R22 and a non-azeotropic mixture of R143a and R124 using perforated foils.

Author(s) : CONKLIN J. C., VINEYARD E. A.

Summary

The paper reports an investigation of the flow-boiling heat transfer from the inside of a smooth tube and a novel surface designed to improve nucleate boiling heat transfer. This surface consists of a perforated brass foil inserted into the smooth tube. Two fluids were investigated: pure R22 and a non-azeotropic mixture of 75% R143a and 25% R124 (by mass). Results are given.
