A Coanda fluidic oscillator has been studied numerically and experimentally to understand
the internal switching mechanism and to estimate the frequency of resulting pulsed jets. 2D …

We experimentally study the unsteady forcing of the turbulent wake of a three-dimensional
blunt body for drag reduction purposes. The forcing is provided by pulsed jets coupled to …

A bi-frequency open-loop control strategy aiming to combine both high-and low-frequency
forcing effects is used to experimentally reduce the drag of a simplified car model at a slight …

The influence of cavitation on the mean characteristics and unsteady behavior of turbulent
separated flows was comprehensively investigated in this study over a microscale backward …

In this study, multi-scale vortical structures and vortex dynamics around a fixed-bed barchan
dune have been experimentally investigated based on the particle image velocimetry …

Flow separation control of a swee** jet actuator in a backward-facing ramp was studied
using two-dimensional and stereoscopic particle-image velocimetry. The actuator was …

This work provides new insight into the transient flow effects of forcing a backward-facing
step flow at high Reynolds number. The detailed flow structure and surface pressure is …

The flow fields and convective heat transfer downstream of a backward facing step (BFS)
with a Re H= 9630 were investigated using experimental methods. The BFS flow was …

Recent studies have shown that entrainment effectively describes the behavior of natural
and forced separating flows develo** behind bluff bodies, potentially paving the way to …

The self-sustained streaks in turbulent backward-facing step flow are experimentally studied
at a step height Reynolds number of 1.0× 10 3. As one of the featured dynamic behaviors …
