RISTurbulent Flow Around Rectangular Cylinders With Different Streamwise Aspect Ratios
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulent flows around a square cylinder and a rectangular cylinder with a streamwise aspect ratio (length-to-height) of 5 in a uniform flow were investigated using time-resolved particle image velocimetry (TR-PIV). The ...
The Effects of Upstream Wall Roughness on the Spatio-Temporal Characteristics of Flow Separations Induced by a Forward-Facing Step
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Separating and reattaching turbulent flows induced by a forward-facing step submerged in thick oncoming turbulent boundary layers (TBL) developed over smooth and rough upstream walls were investigated using time-resolved ...
