摘　　要：舌形挡板涡轮增压器的效率问题一直是制约其发展的关键所在,因此对其蜗壳内流场的仿真就显得很重要。本文通过Pro/E建立蜗壳流动区域的几何模型,而后使用ANSYS-ICEM对模型进行网格划分,然后利用STAR-CD对划分后的网格模型进行了计算。对不同挡板开度时蜗壳内的流场进行了模拟,得到了出口速度的分布状况,这对提高增压器的效率很有帮助。The development of VGT is restricted by its efficiency,therefore the internal flow simulation appears very important.In this paper,through Pro/E based on geometric model of spiral flow area,then ANSYS-ICEM is used to mesh,and then STAR-CD is used to calculate the model of mesh.Flow simulation of different paddle angle in worm shell was carried out.The distribution condition of exit speed was obtained.Therefore it is helpful to improve the efficiency of the VGT.
