The Research Of Performance With Wet Compression And Atomizing System

At present, gas turbines have been applied to more and more areas, how to improve gas turbine performance become a focus of research all over the world. Wet compression technology is one way of improving gas turbine peromance.The technology introduced in this dissertation was drawn comprehensive attention, because of its advantages of simplicity, effectiveness, easy-to-use, and so on. But, excellent atomization apparatus is a main factor to success on the technology of wet compression. In the dissertation, do the further studies on wet compression application in gas turbine. Study on the key technology by experiment and simulation.A new and innovative spray technology-Swirlflsh was studyed.In the dissertation, the basic theory of wet compression was analyzed in the thermodynamics. The loss of wet compression was analyzed . Programmed the compressing model and computed on it. Analysis was made,compared with the manners of atomization, adopting the manner of flashing vaporization at last ; Analysis was made,compared with the injector of atomization ,adopting the centrifugal injector. Design was made for the centrifugal injector. In addition,conducted the simulating calculations for the flow field which made by flashing evaporating through the direct injector and centrifugal injector, get the regularity of atomization by the initial tempreture,the initial pressure and the caliber of injector.Experiment of swirlflash evaporation was made and tested the particle size of experiment at the bench. By the equipment of PDA ,get the distribution of particle size and spray angle , generalize the regularity of influencing the evaporation by the tempreture ,pressure,diametral injector and so on.The experiments and numerical calculations show that the spray device which based on the swirflash technology by the initial tempreture,the initial pressure and the caliber of injector meet the require of wet compression.So the spray device is an ideal atomization device to apply the technology of wet compression to engineering practice.
