摘　　要：通过CFD数值模拟的方法对型号为TE601的EGR阀进行了流固耦合传热的数值模拟。模拟过程使用EGR阀门最大开度进行分析,得到了有无冷却水两种情况下阀体和阀杆的温度场。针对两种情况下的结果进行分析对比,提出了冷却水道的设计方案,为进一步分析计算阀体和阀杆的热应力和热变形提供了理论依据。The numerical simulation for fluid-solid coupled heat transfer of TE604 EGR valve was done by the method of CFD numerical simulation. In the simulation,the opening of control valve set at the maximum value was analyzed,and the temperature fields of the valve body and stem were obtained under two conditions that there has cooling water and no cooling water. Then the design scheme of cooling water channel was proposed through the comparative analysis of the results of two cases,which provides the theoretical basis for further analysis and calculation of the thermal stress and thermal deformation of the valve body and stem.
