摘要
本文在传热方程中采用算术平均温差,改进了换热器模型,对管壳式换热器内温度分布以及结构对传热有效度的影响进行了数值分析,并和Gaddis的模型做了比较。
An improved model is presented for shell-tube heat exchanger by replacing the endpoint temperature difference with the arithmetical mean temperature defference in the heat-transfer equation. The effects of temperature profile and the configuration in shell-tube exchanger on the heat-transfer effectiveness are analysed numerically. The model proposed is compared with Gaddis'smodel.
