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.
