CFD Simulation of Volute of Variable Geometry Turbocharger
To study the Volute of Variable Geometry Turbocharger (VGT) flow field and the possibility of providing the basis theory for control strategy and matching with engine,in this paper,a method is presented.The 3D viscous compressible flow in the model of volute and the vanes is simulated by CFD using FVM (Finite Volume Method).And taking some VGT as an example,the simulation is carried out.The result shows that the method can display the distribution of pressure and velocity in the model clearly.The zone and the reasons resulting in loss will be found after analyzing the results,and then the turbocharger can be optimized and redesigned purposeful to reduce the losses resulted from improper figure.The distribution of pressure and velocity at open and close vanes will be found after analyzing the results,and the basis theory for VGT control strategy and matching with engine can be provided.
