Simulation Analysis of Compressor Flow Field in Vehicle Turbocharger

In this paper, the intake structure design and research of full-wheel turbocharger compressor are based on computational fluid dynamics. In the establishment of compressor calculation model, the geometric model of turbocharger compressor is established by using reverse engineering design method. In the meshing of compressor, a meshing method suitable for turbocharger compressor flow field is proposed. Then, through the flow field analysis, the flow field distribution of each component of the compressor is known, and the distribution of internal pressure and velocity is studied. The guide vanes which connect the impeller flow field with the width of the recirculation channel of the gate and the two shapes of the gate chamber are both taken as the research objects. Finally, the overall performance of turbocharger compressors with different structures and parameters was simulated by using computational fluid dynamics software fluent.
