摘要:
通过对折流板管壳式换热器壳程流体流动和传热特性分析,提出了1种模块综合模拟方法.该方法将折流板管壳式换热器壳程分为进口段、周期段和出口段,并分别进行模拟计算,而后将各部分模拟结果进行综合得到整个壳程的温差和压力降.并通过管壳式换热器传热性能实验和数值模拟结果进行时比,两者吻合较好,证明了该数值模拟方法的正确性.模块综合法可以减少计算模型的网格数量,提高计算速度,而且具有较高的精确性,可以用于较大型管壳式换热器的模拟计算,弥补了传统模拟方法的不足.
Abstract:
Through the analysis of the fluid flow and heat transfer characteristics of the shell of the baffle plate shell and tube heat exchanger, a comprehensive simulation method of one module is proposed. In this method, the shell range of the baffle plate shell and tube heat exchanger is divided into inlet section, cycle section and outlet section, and the simulation calculation is carried out separately, and then the temperature difference and pressure drop of the whole shell range are synthesized by synthesizing the simulation results of each part. Through the heat transfer performance experiment and numerical simulation results of shell and tube heat exchanger, the two are in good agreement, which proves the correctness of the numerical simulation method. The modular synthesis method can reduce the number of meshes in the calculation model, improve the calculation speed, and has high accuracy, which can be used for the simulation calculation of larger shell and tube heat exchangers, which makes up for the shortcomings of traditional simulation methods.
