摘要：

By means of the original method of quantitative thermography, an extensive experimental database on the position, length, and other characteristics of laminar-turbulent transition caused by the development of stationary crossflow vortices initiated by different roughness configurations with documented characteristics was obtained. Accompanying numerical base-flow computations were carried out with commercial gas dynamic software coupled with house-made laminar-turbulent transition module. The experimental and numerical data were used to determine threshold N-factors of transition and turbulence onsets in a range of chord-based Reynolds numbers (flow velocities) and different roughness configurations. The threshold N-factors are presented as functions of surface roughness height. A comparison with findings of other researches is given.
