摘要
采用瞬变测试方法,对5种用于微型燃气轮机中具有高紧凑度的板翅式及一次表面回热器型面的换热特性和阻力特性进行了实验研究,获得了换热表面传热因子j和摩擦因子f的关联式,并对所得到的结果进行了分析和比较.
Transient single-blow testing technology is used to investigate the performances of heat transfer and pressure drop for five testing matrixes of recuperator used in microturbine.The recuperator testing matrixes are highly compact and have different configurations of surfaces with off-set strip plate-fin or are cross corrugated(CC) prime surfaces.The experimental correlations between heat transfer j-factor and friction f-factor are obtained.Analysis and comparison are made for the experimental results.
