摘要
建立了航空发动机用燃-滑油散热器性能分析的理论模型;在换热器传热计算的ε-NTU(效能-传热单元数)法的基础上,提出了1种由1条散热器试验性能曲线推算其性能曲线簇的方法。为有效预测散热器变工况性能提供了1条可行途径。
A theoretical model for performance analysis of fuel -oil radiator for aeroengine was built. A method of radiator performance curve cluster predicted by a radiator test performance curve was presented based on method. The feasible approach was provided for predicting radiator varying duty performance effectively.
