Investigation on the Interaction of an Impinging Jet with Cylinder Wakes
… using the vortices periodically shed from a cylinder placed upstream in a channel with an initial crossflow. Preliminary CFD results prove the hypothesis of jet oscillation induced by the cylinder vortices and that the lateral jet oscillation is an efficient method for uniform distribution of …

Time -Resolved Visualization and Analysis of Compressible Blunt -Base Cylinder Wakes
High-speed flow visualization of these wakes is also performed. Both conventional cross-correlation analysis and cross-correlation analysis conditioned on the coherent structures are performed to measure the convection velocity of the coherent structures. The coherent structures in the developing …

The effects of periodic wake disturbances on flat-plate turbulent boundary layers
… to upstream blades creating unsteady periodic wakes that interact with the boundary layer and free stream flows about downstream blades. This study modelled these flow conditions, with circular cylinders periodically traversing in front of a turbulent flat plate boundary layer inside a low …

Three dimensional topology and structural differences in the turbulent wake of cantilevered square and circular cylinders protruding thin boundary layers
… around cantilevered circular and square-section cylinders to investigate the effects of the cylinder geometry and the boundary layer state on the wake structures and flow topology. Detailed velocimetry results are presented in the wake of circular and square cylinders protruding a thin laminar …

Simulations of droplet dispersion in the wakes of cylinders and icing tunnel spray bars
Simulations of droplet dispersion behind cylinder wakes and downstream of icing tunnel spray bars were conducted. In both cases, a range of droplet sizes were investigated numerically with a Lagrangian particle trajectory approach while the turbulent air flow was investigated with a hybrid …
