湿压缩技术是能够提高燃气轮机性能的一种经济有效的手段。文中采用CFX软件,选择k-湍流模型,利用安托万方程求蒸汽饱和压力,对跨音速一级NASAStage35进行进口加湿湿压缩数值模拟研究。模拟结果表明,当此跨音速压气机运行在靠近失速边界的一段范围内,湿压缩可使其性能提高,而对于靠近阻塞边界的一段范围内,湿压缩却降低了压气机各个性能参数;当压气机运行在设计工况时,在进口喷入较小颗粒尺寸的水滴可降低比压缩功、提高压比及流量并缩小激波后低能流动区域,而在进口喷入较大颗粒尺寸水滴却降低了压气机各性能参数,整个流场也并无改善。 Wet compression technology is a cost-effective means of improving the performance of gas turbines. In this paper, the CFX software was used to select the k-turbulence model and the Antoine equation was used to find the steam saturation pressure. The numerical simulation of inlet humidification and wet compression was performed on the first transonic NASAStage35. The simulation results show that when the transonic compressor operates within a range near the stall boundary, wet compression can improve its performance, while for a range of close to the blocking boundary, wet compression reduces the performance parameters of the compressor; when Compressor operation in the design conditions, the import of small particles sprayed into the water droplets can be reduced than the work of compression, to improve the pressure ratio and flow and reduce the shock wave after the low-energy flow area, and imports at the entrance of larger particles of water droplets are Reduced the performance parameters of the compressor, the entire flow field has not improved.
