Thermodynamic Research And Numerical Simulation Of The Wet Compression Compressor

Wet compression is an effective way of gas turbine power augmentation, but at the same time it causes some new thermodynamic problems. How to evaluate the thermodynamic parameters and how to improve the wet compression process and wet compression gas turbine cycle are key to the actual applications of the technique in industries.From the entropy and exergy views, wet compression processes are analyzed in this paper. By calculating the entropy and exergy variations with the established thermodynamic models of wet compression process, we presented some interesting results that could used to reduce the increase of entropy and the loss of exergy in the wet compression process. On the basis of thermodynamic analysis of wet compression, the entropy and exergy effects at different evaporative rates, different pressure ratios etc. are further investigated in this paper.The thermodynamic analyses and actual applications of wet compression has demonstrates the benefits of the wet compression technology. The aerodynamic flow field of the wet compression compressor cascade can give more information about the internal flow patterns. The water droplets movement path, the water droplets evaporation process, the effects of phase change and correspond latent heat on the internal fluid field are deserved to investigated in detail.The current development of computer techniques and computational fluid dynamics (CFD) has made it possible to employ a numerical simulation method for performing the full three-dimensional simulation calculation of a real flow field.
