Abstract : a mathematical model describing the effect of flow nonuniformityon the performance of compact heat exchanger is provided, which is based on that one side of heat exchanger is uniformly distributed but the other is of maldistribution. the model may be expressed in two different types, i. e., continuous model and discrete model. the former provides a method analyzing the performance deterioration of exchanger due to flow maldistribution, and the latter provides a reference to the improvement of experimental measurement. the analyzing method obtained can be used to compute the performance deterioration of compact heat exchanger due to flow maldistribution. the result is significant to the optimization of compact heat exchanger design
文摘:以一側流體分配不均勻的換熱器模型為基礎，建立了物流分配不均勻性對換熱器效能影響的數學模型，通過理論分析和計算，為研究換熱器內部物流分配不均勻對其效能的影響提供了一種分析方法.該理論模型包括連續模型和離散模型2種形式，前者為研究物流分配不均勻引起換熱器效能的下降提供了一種分析計算方法，後者為控制實驗研究的精度提供了理論依據.研究結論對換熱器的優化設計具有重要意義 -
The numerical results show that because of the temperature variation of cooling water along its flow direction the heat load of the second - pass tube bundle is lower than that of the first - pass tube bundle, which brings about the steam flow deflection and then the deterioration of heat transfer
