Survey of the experimental investigations of the boundary layer by-pass transition at the Institute of Thermomechanics
The effect of turbulence length scale onflat-plate by-pass boundary layer transition under free stream turbulence has been investigated. The results document a significant effect of turbulence length scale on the o...

Turbulent spots during boundary layer by-pass transition
The investigation of the spots behaviour was performed during boundary layer transition at various free stream turbulence scales. It was ascertained that at the beginning of transition the spot occurrence is more n...

By-pass transition of flat plate boundary layers on the surfaces near the limit of admissible roughness
It was certied that both the wall roughness and the free stream turbulence accelerate individually the boundary layer development from the laminar state of boundary layer to turbulence. Next it was ascertained that...

On turbulent spots during boundary layer by-pass transition
The wall-friction records made in the transitional region of boundary layer were analysed using Narasimha's transitional intermittency concept and wavelet analysis. The distributions of the dimensionless spot produ...

A comment on the choice of intermittency measurement method for by-pass transition investigation.
The relevance of the investigation of the intermittency factor distributions inside transitional boundary layers is discussed. The prepaired procedure is outlined of measurements and evaluations of the intermittency factor....

The intermittent nature of the flow in a transitional boundary layer.
Two ways how to cause the start of the boundary layer transition by the control of the scales of the outer stream turbulence are experimentally proved. Further the developed procedure is described of the evaluation of the i...

Transitional intermittency in a rough wall boundary layer
The transitional intermittency factor distributions were evaluated from the wall friction records acquired in the rough wall boundary layer under free stream turbulence. Important characteristics of by-pass tra...
