Optimization design of diffusers for supersonic separators

摘要：

　　The diffuser is the key part of a supersonic separator,which is a new device for natural gas separation.In this paper,three diffusers are designed for the supersonic separator.The fluid flow in the diffuser is numerical calculated,using the RNG k-ε turbulence model.The behavior of gas dynamic parameters is analyzed under conditions of shock waves and boundary layers.The numerical results show that the second throat diffuser is a good choice for the supersonic separator,both from the perspective of the pressure recovery and adjustment to the back-pressure changes.
