一、前言 研究混合气中含有湿蒸汽凝结的透平工作过程是能源有效利用中的一个实际课题。过程的特点是气体部份的流量不断变化,凝结释放的潜热不断加热主流,排气温度将比不含蒸汽凝结的情况为高,且输出功增加。凝结释热过程也使透平内部流场发生变化。 I. Preface It is a practical issue to study the turbine working process of condensing wet steam in the mixture, which is an effective subject of energy utilization. The process is characterized by constant changes in the flow of gas, the latent heat released by condensation continuously heating the mainstream, the exhaust temperature will be higher than the case without steam condensation, and the output work increased. The condensation heat release process also changes the flow field inside the turbine.
