Bypass boundary layer transition in flows on rough surface on flat plate was investigated experimentally. It was measuered cases with combination of roughness of surface by different free stream turbulence intenzity. Hot wire anemometry technique was used. Measuerement were made on flat plate in closed wind tunnel. Flat plate was covered by different roughness foils (sandpapers). Adverse pressure gradient was set by diffuser in tested section of wind tunnel. Grid turbulence of free stream was controlled by grid. Hot wire anemometry technique was used, intermitency factor was evaluated.
