Numerical study on condensation of R134a refrigerant in microchannel

The action of capillary forces during flow condensation of refrigerant R134a in rectangular microchannel is considered numerically using the annular flow model. It was shown that significant accumulation of the liquid occurs near the channel corners and causes the heat transfer enhancement. The heat...
