本文对边界层转捩过程中自然产生的湍流斑的传播进行了实验研究。宽带宽的热传递仪器被用来跟踪个别cubulent斑点，因为他们的进展下一个平板表面充分发展的湍流。对流率的湍流/非湍流界面的斑点在流向的方向进行了测定，作为横向传播的速率。压缩性和有利的压力梯度的单独影响进行了评估，并已报告了一些典型的结果。
An experimental investigation of the propagation of turbulent spots occurring naturally during boundarylayer transition was conducted. Wide-bandwidth heat-transfer instrumentation was used in tracking individual cuibulent spots as they progressed down a flat-plate surface toward fully-developed turbulence. The convection rates of the turbulent/non-turbulent interfaces of the spots in the streamwise direction were determined, as were rates of lateral spreading. The separate effects of compressibility and favourable pressure gradients have been assessed, and some typical results have been reported.
