Study of Heat and Mass Transfer Process In the Heat Pipe-type Absorber

本文对升温型吸收热泵热管式降膜吸收器溶液吸收传热传质并通过热管移出吸收热的过程进行了数值研究。根据所求得的波动膜流解及建立的数学模型，通过求解热管加热段外壁面溶液波动降膜传递方程和热管传热方程，研究了膜雷诺数。低位余热温度、输出热温度等因素对传热传质过程的影响，对今后的研究工作提出了新的见解。

A numerical study of the heat and mass transfer process of tile solution absorptionand the moving out of absorption heat through heat pipe in heat pipe-type falling film absorber was presented. According to the wavy film flow solution solved and the mathematicalmodel built, the influences of film Reynolds number, low grade waste heat temperature,output heat temperature etc. on the heat and mass transfer process were studied throughsolving the tansporting equations of wavy falling solution film on the outside wall of heatingsection of heat pipe and the heat transfer equations on heat pipe. The new ideas were put rorward on the rurther work.
