摘要

The cross-flow heat exchanger model based on distributed parameter method which could be applied further in a complex system simulation is established in this paper. Then both steady and transient simulations of a triangle plate-fin cross-flow heat exchanger are achieved. The conclusion indicates that there is a critical point, when the number of distributed elements continues to increase, errors can be neglected. In dry air condition, steady results are proved identical to the ones of the well-known effectiveness-NTU method. Transient simulations are also participated under both dry air and moist air conditions in the interest of discussing the dynamic performance of the heat exchanger,and latent heat shows a great influence on the outlet temperature in moist air condition. Moreover, the effect of fouling is studied as a modification. All the simulations are performed on the commercial software Flow master.
