In this study we focus on the control of the dynamics of 3D turbulent wake downstream a square-back Ahmed body ($Re_H=3.9\times10^5$). The peculiar dynamics of such a wake is first characterized through the trajectories of the pressure barycenter over the rear part of the model as well as the recirculation barycenter in the wake. In particular it is shown that these dynamics allow the definition of three different states: the two so-called reflectional symmetry-breaking (RSB) modes and the… 

An LES Investigation of the Near-Wake Flow Topology of a Simplified Heavy Vehicle

Recent experimental investigations by McArthur et al. (J. Fluids Struct. 66, 293–314, 2016) in the wake of a simplified heavy vehicle or commonly known as the ground transportation system (GTS) model

Characterisation of the unsteady wake of a square-back road vehicle

Square-back shapes are popular in the automotive market for their high level of practicality. These geometries, however, are usually characterised by high aerodynamic drag and their wake flow

Proof-of-concept study of sparse processing particle image velocimetry for real time flow observation

In this paper, we overview, evaluate, and demonstrate the sparse processing particle image velocimetry (SPPIV) as a real-time flow field estimation method using the particle image velocimetry (PIV),

The chaotic dynamics of large-scale structures in a turbulent wake

The dynamics of a 3D bimodal turbulent wake downstream a square-back Ahmed body are experimentally studied in a wind-tunnel through high-frequency wall pressure probes mapping the rear of the model

Imperfect supercritical bifurcation in a three-dimensional turbulent wake.

This promising experiment indicates the possible existence of an unstable solution branch corresponding to a reflectional symmetry preserved (RSP) mode and is encouraging to develop a control strategy based on a stabilization of this RSP mode to reduce mean drag and lateral force fluctuations.

Stochastic modelling and feedback control of bistability in a turbulent bluff body wake

A specific feature of three-dimensional bluff body wakes, flow bistability, is a subject of particular recent interest. This feature consists of a random flipping of the wake between two asymmetric

Simulation and feedback control of the Ahmed body flow exhibiting symmetry breaking behaviour

The present work considers the low-Reynolds-number wake flow behind a squareback Ahmed body, in close proximity to a ground. At low Reynolds numbers such wakes are known to undergo a series of

Experimental sensitivity analysis of the global properties of a two-dimensional turbulent wake

Abstract The sensitivity of the global properties of a two-dimensional turbulent wake produced by the separated flow of a ‘D’-shaped cylinder at $\mathit{Re}= 13\hspace{0.167em} 000$ is investigated

Statistical axisymmetry of the turbulent sphere wake

The turbulent sphere wake is studied experimentally at $${Re}=1.9\,10^4$$Re=1.9104 using an axisymmetric support that holds the body from upstream. This setup allows the axisymmetry of the mean wake

The nature of the vortical structures in the near wake of the Ahmed body

This study presents the results from high-spatial-resolution water-channel velocity-field measurements behind an Ahmed body with 25° rear slant angle. The Ahmed body represents a simplified generic

A dynamical systems approach to the control of chaotic dynamics in a spatiotemporal jet flow.

A strategy for control of chaos in open flows is presented and its experimental validation in the near field of a transitional jet flow system is provided, resulting in a simple and effective control algorithm.

Forcing symmetry exchanges and flow reversals in turbulent wakes

Turbulent wakes past bluff bodies commonly present asymmetric flow states reminiscent of bifurcations in the laminar regime. Understanding the sensitivity of these states to flow forcing is crucial
