【摘要】 为了研究燃气轮机进气空气状态对其管道内液滴汽化长度的影响,采用DPM模型方法从进气温度、相对湿度、进气速度3方面对进气管道内喷雾直接蒸发冷却进行数值模拟和分析。模拟结果表明:进口空气温度越高,相对湿度越大,液滴在管道内汽化长度越短;适当地降低进口风速有利于降低液滴的汽化长度;雾化液滴的直径越小液滴汽化距离越短。更多还原

【Abstract】 The gas turbine inlet air spray evaporative cooling system humidifies and cools the inlet air to reduce the inlet air temperature. Based on the basic theory of humidification process, this paper uses MATLAB programming to calculate and analyze. Through calculation and analysis, it was found that the air temperature and relative humidity have a significant effect on the cooling effect. The higher the air temperature, the lower the relative humidity and the better the cooling effect. It is estimated that the economy of a unit in Northwestern China after adopting a spray evaporative cooling system fully demonstrates the superiority of the cooling system for gas turbine units in the Northwest China.更多还原
