Abstract
In order to investigate the flow nonuniformity of printed circuit heat exchanger for natural gas, a porous medium model of printed circuit heat exchanger was established, and the feasibility of using this model to predict the flow characteristics of natural gas was evaluated. Firstly, the parameters of the porous model were obtained from the the flow characteristics of the single channel, and then the flow field characteristics of large-scale printed circuit heat exchangers were calculated by using this model. Results show that the porous medium model could well predict the pressure field and flow nonuniformity of the actual model in the laminar flow range (Re≤1 200), and the deviation is basically within 5%. Increasing the channel length is beneficial to improving the accuracy of the porous medium model when Re=10 000 and the number of channels is 8.
