Abstract: The wake flow originated by three-dimensional bluff bodies having the different aspect ratio is experimentally studied in this paper. The turbulent wakes generated by asymmetric- and semi-cylinders were first measured by the high-speed PIV. The… read more here.

Abstract: The causative factors leading to the Reynolds shear stress distribution in turbulent channel flow are analysed via a backward particle path analysis. It is found that the classical displacement transport mechanism, by which changes in… read more here.

DOI: 10.1063/5.0043953
Abstract: Proper scaling for the mean transverse flow and Reynolds shear stress in a turbulent plane jet is determined using a scaling patch approach. By seeking an admissible scaling, a key concept in the scaling patch… read more here.
