The effect of height of a trip and its location on the transition of boundary layer on a cylinder is studied using large eddy simulations for 2 × 10 3 ≤ R e ≤ 5 × 10 5. The Reynolds number, Re, is based on the free stream speed and diameter of the cylinder (D). Two modes of transition are observed:...
