板翅式回热器传热性能研究

Investigations on heat transfer performance of a plate-fin recuperator

对板翅式回热器的传热性能进行了实验和数值模拟,对板翅式回热器的传热性能以及其温度场和速度场的情况进行了分析,为今后的此种换热器的设计与改进提供了一定的理论依据。并且为研究板翅式气-气回热器在高温下的传热规律,分析参与换热两侧流体的传热特性,做出了初步探讨。

Heat transfer performance of a plate-fin recuperator was studied experimentally and numerically in this paper. The temperature and velocity fields were obtained and analyzed, which provide theoretical basis for future design and improvement of the recuperator. A preliminary discussion was made for further investigations on heat transfer performance of the recuperator at high temperatures.
