Abstract

Abstract: The objective of this work was to investigate nucleate pool boiling heat transfer performance and mechanism of R134a and R142b on a twisted tube with machine processed porous surface(T-MPPS tube)as well as to determine its potential application to flooded refrigerant evaporators.In the experimental range,the boiling heat transfer coefficients of R134a on a T-MPPS tube were 1.8-2.0 times larger than those of R134a on a plain tube. In addition,the developed experimental correlations verified that the predictions of the heat transfer coefficients of boiling R134a and R142b on a T-MPPS tube at the experimental conditions were considerably accurate.

Key words: nucleate pool boiling, heat transfer enhancement, twisted tube with machine processed porous surface
