Large eddy simulations on film cooling hole array on a flat plate was carried out to investigate upstream turbulence effect. Circular cylinders were configured to create a turbulent boundary layer and its diameter has been adjusted to generate 13% upstream turbulence intensity in the main flow. Due to the small pitch to diameter configuration of the cylinder. two-dimensional LES analy... https://www.hindigyanvishv.com/hot-find-Facia-Installation-Kit-Suits-Holden-Commodore-VE-Series-2-FP9550BK-Black-top-mega/
