An assessment of refrigerant heat transfer, pressure drop, and void fraction effects in microfin tubes.

Author(s) : NEWELL T. A., SHAH R. K.

Summary

This review focuses on the performance of microfin tubes and details known information as well as information that has yet to be obtained. Generally, microfins enhance heat transfer by an amount that is similar to or greater than the amount of surface area added to the internal wall surface. Pressure drop does not tend to increase significantly; however, the range of reported pressure drop effects is broad. Oil generally reduces heat transfer and increases pressure drop.
