Prediction of flow maldistribution in printed circuit heat exchanger

International Journal of Heat and Mass Transfer, 2020
Abstract The printed circuit heat exchanger (PCHE) is widely used in a variety of extremely high temperature and high pressure applications. Since the PCHE is a typical multi-channel heat exchanger, the flow maldistribution may happen in the PCHE channels. In this paper, a new mathematical model is established to predict the flow maldistribution in a
