Flat Plate Boundary Layer Transition Affected by the External Turbulence and Surface Roughness

Original language description

The joint action of the external ow turbulence (with intensities from 0.003 up to 0.05 and length scales from 0.002 m up to 0.031 m) and the surface roughness (caused by sandpaper with grids 60, 80 and 100 respectively) on the at plate boundary layer transition is investigated and compared with the by-pass transition on the smooth surface at identical boundary conditions. The existence of the laminar/transitional region and the action of external turbulence were proved regardless the surface roughness.
