| Abstract: | This paper investigates the phenomena of turbulent bursting events, and to make a comparative study among the events in the scour geometry developed by short circular cylinders of fixed length with different diameters placed on the sand bed transverse to the flow. The distributions of turbulent kinetic energy (TKE), turbulent diffusion in both longitudinal and vertical directions at different locations of scour marks, and the contributions of burst-sweep cycles to the Reynolds shear stress are presented. |
