由模拟试验得到的舌形ＶＧＴ蜗壳内的流动模型和进出口的速度系数，为该产品的设计和结构优化提供了理论依据。在匹配试验中总结了多种效应的相互影响和渗透，提示了舌形ＶＧＴ的发展前景。
The flow model in the volute VGT volute and the velocity coefficient of the inlet and outlet obtained from the simulation test provide the theoretical basis for the design and structural optimization of the product. In the matching experiment, the interaction and infiltration of various effects were summarized, which indicated the development prospect of tongue-shaped VGT.
