Application and Flow Field Simulation of a Miniature Centrifugal Compressor
Through the working principle of a distributed compression and cyclone ram engine,the design of the compressor and matching parts and the flow field simulation of two-stage centrifugal compressor are carried out,and the design and flow field simulation of the tail nozzle part are also carried out.The design and analysis process of 3D modelling is as follows:based on the known flow rate of the centrifugal compressor,the two-stage centrifugal compressor and the connected tail nozzle are designed,and the velocity and pressure flow field are analysed according to the finite element software.The flow field is analysed by the flow field analysis of the pressurizer with one,two and three stages to analyse the conditions to make the gas reach supersonic speed.
