摘要: Abstract : The present research is centered around the experimental investigation of seven various shaped single roughness elements and their effects on turbulence quantities in a two-dimensional turbulent boundary layer. under scrutiny are as follows: cone, cone with spatial variations equal to smallest sublayer structure length scale, 2.5 times Gaussian-shaped element, hemisphere, cube aligned perpendicular flow (cube at 90 degrees), rotated 45 degrees relative flow.
