摘　　要：对单弓形折流板式换热器的结构进行合理简化,利用ANSYS参数化建模方法建立了管壳式换热器的参数化模型,在ANSYS FLUENT 14.0数值模拟软件中对其温度场和流场进行数值模拟。将定壁温假设方法与同时考虑壳程和管程流体的两流程耦合计算方法的模拟结果进行对比,结果表明:同时考虑壳侧和管侧流体流动与传热,更有助于揭示换热器局部温度场变化的实际情况,模拟结果与实际情况吻合较好,能够为管壳式换热器结构优化设计提供更好的参考依据。The structure of single bow baffle plate heat exchanger was simplified reasonably, and a parametric model on the shell- tube heat exchanger was established using ANSYS parametric modeling method. The numerical simulation on the temperature field and flow field of shell-tube heat exchanger was performed on ANSYS FLUENT14.0 numerical simulation software. Two numerical simulation models were taken into account. The results showed that the heat transfer model of both the shell side and the fluid flow can exhibit the local temperature change of heat exchanger truly. The simulation results are agreement with the actual situation and can provide a reference for the structure optimization design on shell- tube heat exchanger.
