再生式换热器的实验研究与数值模拟

Simulation and Experimental Research of Regenerative Heat Exchanger

为了解再生式换热器工作特性,采用Matlab软件计算简化后的模型,对换热器内流体和固体的温度分布进行了数值模拟,并进行了实验验证。研究了蓄热体长度、比表面积、速度和蓄热体材质对换热效果的影响。结果表明,面积和流速对换热效果影响明显,而改变蓄热体材质基本无影响。

In order to understand the regenerative heat exchanger operating characteristics, the Matlab software was used to calculate the sim- plified model. A numerical simulation and experimental research of fluid and solid temperature distribution within the heat exchanger was im- plemented. Affect of length and surface area and material of the regenerator was researched. The results show that the area and flow rate have much effect on heat transfer, changing the material of the regenerator had no influence.
