| Summary: | and concave surfaces respectively) and pressure gradient was and pressure gradient effect was not strong enough to cause a both surfaces. Goertler vortices observed on concave surface Effect of freestream turbulence on concave and convex effectiveness of the device. examined. Turbulence levels of 3.6 and 8.5 percent were generated with the help of two grids of 93 and 71 percent Large Eddy Breakup device. The skin friction increased on manipulation on concave wall was also studied by using a measured boundary layer profiles. A rake of Preston tubes porosity respectively. Skin friction was determined from the predominant effect of concave curvature. However, in the recover from the curvature effect. Effect of outer layer recovery section, a decrease in skin friction indicated the substantial growth of the internal layer. Measurements in surfaces with mild curvature (5/R-0.016 and 0.022 for convex the concave wall despite using the device showing a the recovery section showed that the boundary layer did not was used to measure spanwise skin friction distribution on were present even at higher turbulence level. The curvature |
