Experiment Research And Numerical Simulation Of The Wet Compressin Of Centrifugal Compressor

At present, gas turbines have been applied to many areas, special for the market of power equipments, how to improve gas turbine performance becomes a focus of research all over the world. Wet compression introduced in the thesis, which has advantages of simplicity, effectiveness, easy-to-use, and so on, has drawn comprehensive attention.Wet compression process has great difference from general dry air compression process, so need to reserch in theory. In the thesis, ideal wet compression concept was given according to the basic thermodynamics analysis, and the wet compression efficiency was defined also. The discrete phase model of the software of fluent was detailed introduced in the thesis, and with this to make the numerical simulation of the connecting pipe of the two-classeses wet compression rig, comparing with the dry compression's simulation result, getting the spray of water's result well, making sure the better spray's place.In the calculation data processing, flow temperature to lower, the pressure's loss to higher, the accumulating water place to fix and the spray water's quantity decrease etc.The improved wet compression rig's system work well, on the foundation two-classes wet compression rig was designed. From a great deal of fogging experiment, getting that the direct-flash technique can satisfy the experiment. A lot of wet compression's experiment were made on the sigle-stage experiment, the results show that wet compression increases compressor's mass flow, heighten the ratio of pressure, lower temperature of compressor outlet.
