本文论述了氟里昂卧式壳管式冷凝器的计算机模拟。建立了传热的数学模型。通过对偏微分耦合方程的求解,得出了内部温度场,局部换热量及换热系数变化的规律。这一模型可用来预测冷凝器的换热性能和优化结构参数。为验证数字模型的正确性,在实验用的冷凝器上进行了温度分布的测定。结果表明与模拟计算吻合较好。 This article discusses the computer simulation of Freon horizontal shell and tube condensers. Established a mathematical model of heat transfer. By solving the partial differential equation, the law of internal temperature field, local heat transfer and heat transfer coefficient are obtained. This model can be used to predict the heat transfer performance of the condenser and to optimize the structural parameters. To verify the correctness of the numerical model, the temperature distribution was measured on an experimental condenser. The results show that the simulation is in good agreement.
