Distribution of intermittency factor on rought wall boundary layer
Hladík, Ondřej ; Jonáš, Pavel ; Uruba, Václav ; Mazur, Oton
In the paper two methods of transitional region determination for various cases of smooth or rought flat plate with free-stream or increased free-stream turbulence are shown. Estimations of the position and the lenght of transitional region based on distribution of skin friction coefficient are compared with estimations based on distribution of intermittency factor.
Boundary layer by-pass transition by joint action of surface roughness and external turbulence
Hladík, Ondřej ; Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
Results of the experimental investigation of the development of boundary layers on flat plates with the smooth surface and with the surfaces covered by sand-papers 60-grit, 80-grit and 100-grit under external turbulent flows of various grid turbulence scales are presented.
