CFD simulation of R134a and R410A two-phase flow in the vertical header of microchannel heat exchanger.

Summary

This paper studies refrigerant maldistribution in the vertical header of microchannel heat exchanger through both experiment and CFD simulation. In the experiment, the two-phase R134a or R410A is circulated into the transparent vertical header through multi-parallel microchannel tubes in the bottom pass and exits through multi-parallel microchannel tubes in the top pass representing the flow in the heat pump mode of a reversible system. The experimental results are compared with CFD simulation. The Eulerian-Eulerian model in the commercial software Fluent is used to conduct simulation. Qualitative agreement between experiment and CFD is obtained. Both experiment and CFD show that the distribution is worse with respect to inlet quality due to the flow pattern in the header. With CFD simulation, pressure drop and void fraction information in the vertical header is obtained.
