摘要
针对直接蒸发冷却系统,考虑了因水蒸发或凝结而引起的水的质量变化和空气的质量变化,推导出描述泡沫陶瓷填料表面以湿空气与冷水的温差和水蒸气分压力差为驱动力的热质传递过程的微分方程组,建立了模型。利用实验数据对数值解进行了验证,分析了干空气质量流速和冷水质量流速对泡沫陶瓷填料热质传递性能的影响。
For direct evaporative cooling system, a mathematical model of air and water flow on foam ceramic fillers surface was set up to investigate heat and mass transfer performance. The differential equations of heat and mass transfer procedure, which takes the temperature difference of wet air and cold water as well as the partial pressure difference water vapour as the driving force in foam ceramic fillers, are derived. The numerical solution of these differential equations is verified with experimental data and the effect of air mass velocity and cold water mass velocity on the performance of heat and mass transfer of foam ceramic fillers is analyzed.
