摘要
根据热湿交换理论建立了管式蒸发冷却器的数学模型,采用四阶Runge-Kutta方法对该模型进行了数值求解,并将计算结果与实验数据进行了对比,结果表明计算值与实验值吻合较好,证明用数值分析的方法研究类似的工程问题是可行的。分析了运行参数对蒸发冷却器冷却性能的影响,并得到了一些有价值的结论。
The mathematical models for tube evaporative cooler were established based on the heat and mass transfer theory.The models were calculated by numerical method (4th order Runge-Kutta) and the calculating results were compared with the experimental results.The calculation results were in quite good agreement with that of the experiment by comparison,and the feasibility to study the similar engineering problems with numerical calculation was validated.The influence of operating parameters on the evaporative co...
