Abstract: Using computational fluid dynamics (CFD) simulation, flow distribution in a gas cooler with micro-channel parallel flow is studied. It is found that the penetration depth between inlet header and tube, the length of tube, and the penetration depth between outlet header and tube have influence on the flow maldistribution among tubes, which is significant to the design of microchannel parallel flow gas cooler.

Key words: microchannel parallel flow gas cooler, flow maldistribution, simulation
