| 摘 要： | A fluid flow model of distributor was set up to investigate the effectof distributor configuration on the fluid flow distribution in plate- fin heat exchanger. At the same time, a mathematical equation was developed to generate different types of fluid flow maldistribution models considering the possible deviations in fluid flow. Using these fluid flow models, the fluid flow distributions in plate- fin beat exchanger were calculated for different configurations and operating conditions. The computational results show that nonuniform inlet velocity, inlet angle, and orifice diameter on the fin are the main factors affecting the distribution performance of distributor. The fluid flow distribution in plate- fin heat exchanger can be effectively improved by changing the distributor configuration. The distributor reaches the best distribution performance when the orifice diameter is 2 mm. The computational results are in good agreement with experimental ones.

The fluid flow distribution in plate- fin heat exchanger can be effectively improved by changing the distributor configuration.
