摘要
对某型飞机上应用的一种叉流板翅式热交换器的动态性能进行了计算研究，分别用数值计算方法和参数集中方法进行了计算，给出了计算比较的结果．结果表明，这２ 种方法计算所得的结果很接近，但是参数集中法计算程序更为简结。
The dynamic performance of a single pass gas to gas crossflow heat exchanger with high speed air flow that is used in airplane has been calculated with both lumped parameter model and numeric method model. The calculation results under typical conditions of these two methods are very similar,but the lumped parameter model is more simple than numeric method and easy to be used in programming. It also has satisfying precision and can meet the demand of system simulation.
