Numerical Simulation and Structural Optimization Analysis of a Vortex Chamber Supercharge

In order to enhance the efficiency and stability of the vortex chamber supercharger in conveying media, models of vortex chamber superchargers with different diameters were constructed. The FLUENT simulation software was employed to perform mesh generation and numerical simulation of the fluid domain, obtaining the internal fluid velocity, pressure distribution, and motion trajectories for each model. The fluid characteristics of different vortex chamber models were analyzed to identify their operational patterns. The results indicate that as the diameter of the vortex chamber increases, the working efficiency of the vortex chamber supercharger first increases and then decreases. When the diameter of the vortex chamber is 50 mm, a significant vortex phenomenon occurs in the area near the center of the vortex chamber, forming a distinct low-pressure zone and increasing the fluid velocity at the inlets on both sides of the axial direction. The average velocity at the inlets on both axial sides reaches its maximum value of 10.55 m/s, and the working efficiency is the highest at 17.7%.
