Abstract The capability of Large Eddy Simulations (LES), Improved Delayed Detached Eddy
Simulations (IDDES) and Reynolds-Averaged Navier–Stokes Equations (RANS) to predict …

While flow-induced vibration of bluff bodies has been extensively studied over the last half-
century, only limited attention has been given to flow-induced vibration of elastically …

This study investigates the effect of aspect ratios (Ra*) on the wake bi-stability behind the
GTS model using improved delayed-detached eddy simulation (IDDES) at a Reynolds …

Recent experimental investigations in the wake of an idealised car model–the Ahmed body
showed the existence of two stable wake states: flow state I, where the flow is fully separated …

An experimental study was performed on two elongated bluff bodies with underbody gaps, a
square-back Ahmed body and a cuboid, to investigate the effects of geometry and the …

This study numerically investigates the effects of aspect ratios on the wake flow of a
simplified ground transportation system (GTS) model using improved delayed detached …

The standard Ahmed body (SAB) with a rectangular rear end is a simplified, canonical bluff
body geometry that shares similarities with generic road vehicles. It is known to produce flow …

Given the complexity of the wind environment around bridge–tunnel sections in canyons,
flow fields are complex and changeable, resulting in transient aerodynamic loads on …

Through numerical simulations, the interaction between the longitudinal c-pillar vortices and
the flow over the rear slant surface is established for an Ahmed-body geometry as its aspect …

Experimental analyzes were performed to understand the drag evolution and the flow field
modifications resulting from afterbody rounding on the Ahmed body, a simplified vehicle …
