Abstract

Highlights: Heat transfer and pressure drop characteristics of offset strip fin were reviewed. Both single phase and two phase flow over offset strip fin were analyzed. Correlations of heat transfer and pressure drop were summarized. Performance of heat exchangers with offset strip fin were reviewed. Abstract: Offset strip fin is widely used to enhance heat exchanger's performance. The state-of-the-art of experimental and numerical researches of offset strip fins and its applications were reviewed in the present paper. The characteristics of heat transfer and frictional pressure drop of offset strip fins with different geometries and working fluids were analyzed including single phase flow (water, air, oil) and two phase flow (refrigerant). The proposed empirical correlations from literatures were summarized for both single phase flow and two phase flow. Its application in compact heat exchangers was also reviewed comprehensively.
