摘要: 以弓形折流板为基础,设定相同的工况条件,用FLUENT软件对曲面、球面和弓形三种折流板型的换热器壳程流体的流动和传热性能进行模拟,并对三种板型的管壳式换热器壳程压降及换热系数进行比较分析。通过对比三种板型换热器的传热性能及压力、温度和流速云图,分析了产生传热性能差异的原因。研究结果可为管壳式换热器折流板设计及强化传热性能提供参考,具有一定的工程实际意义。

Abstract: Based on the bow baffle, the same working conditions are set. The FLUENT software is used to simulate the flow and heat transfer performance of the shell, fluid and heat transfer of the three baffle plates of curved, spherical and arched shapes. and the pressure drop and heat transfer coefficient of the shellandtube heat transfer with three types of plate are compared and analyzed. By comparing the heat transfer performance, pressure, temperature and velocity nephograms of the three plate heat transfer, the reasons for the difference in heat transfer performance are analyzed. The research results can provide reference for the design and heat transfer enhancement of the shell and tube heat transfer baffle, which has certain engineering practical significance.
