RISStreamwise Aspect Ratio Effects on Turbulent Flow Separations Induced by Forward–Backward-Facing Steps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Separated and reattached turbulent flows induced by two-dimensional forward–backward-facing steps (FBFS) with different streamwise lengths submerged in a thick turbulent boundary layer (TBL) are investigated using time-resolved ...
The Wake Dynamics Behind a Near-Wall Square Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particle image velocimetry is used to experimentally study the wake dynamics behind a near-wall square cylinder subjected to a thick oncoming turbulent boundary layer. The turbulent boundary layer thickness was 3.6 times ...
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 ...
