| 摘 要： | In order to study the effects of wet compression on a transonic compressor,a full 3-D steady numerical simulation was carried out under varying conditions.Different injected water flow rates and droplet diameters were considered.The effect of wet compression on the shock,separated flow,pressure ratio,and efficiency was investigated.Additionally,the effect of wet compression on the tip clearance when the compressor runs in the near-stall and stall situations was emphasized.Analysis of the results shows that the range of stable operation is extended,and that the pressure ratio and inlet air flow rate are also increased at the near-stall point.In addition,it seems that there is an optimum size of the droplet diameter.

| Abstract: | In order to study the effects of wet compression on a transonic compressor, a full 3-D steady numerical simulation was carried
out under varying conditions. Different injected water flow rates and droplet diameters were considered. The effect of wet
compression on the shock, separated flow, pressure ratio, and efficiency was investigated. Additionally, the effect of wet
compression on the tip clearance when the compressor runs in the near-stall and stall situations was emphasized. Analysis
of the results shows that the range of stable operation is extended, and that the pressure ratio and inlet air flow rate are
also increased at the near-stall point. In addition, it seems that there is an optimum size of the droplet diameter. |
