摘要
研究等流量法在高温回热器试验台上的应用.用等流量法(修正的等雷诺数方法)对75kW回热器进行传热性能试验,并进行传热数据分析.从总传热系数K中分离两侧的表面传热系数h,获得了有工程应用价值的Nu Re准则关系式.
The application of equal mass flow method in high temperature recuperator test system is discussed.The heat transfer performance of recuperator is investigated,and the heat transfer data are analyzed.The convective heat transfer coefficient h is calculated from total heat transfer coefficient by use of equal mass flow method (modified equal Reynolds number method),and the Nu-Re dimensionless equation which is of engineering application value is obtained.
