本文报道了平板上完全建立的振荡湍流边界层局部换热系数的测量结果。在频率为0.1 ~ 200 cps、振幅为自由流平均速度的8%~ 92%的范围内，局部努塞尔数增加了3%~ 5%。由此得出结论，在低驻波比的振荡流中，有时报告的局部系数的大幅增加可追溯到降低的过渡雷诺数。版权所有© 1969 by ASME
Measurements of local heat transfer coefficients in the fully established oscillating turbulent boundary layer over a flat plate are reported. In the range of frequencies from 0.1 to 200 cps and amplitudes from 8 to 92 percent of the freestream mean velocity increases in local Nusselt numbers of 3 to 5 percent were found. It is concluded that substantial increases in local coefficients sometimes reported in oscillating flows of low standing wave ratio may be traced to reduced transition Reynolds numbers.Copyright © 1969 by ASME
