The aim of this research work is to analyse the large scale response of a vehicle wake to on-road perturbations by using an instrumented vehicle and a combination of scale one wind tunnel tests, track trials and on road experiments. More precisely, i

In the search for zero-carbon emissions and energy supply security, hydrogen is one of the fuels considered for internal combustion engines. The state-of-the-art studies show that a good strategy to mitigate NOx emissions in hydrogen-fueled spark-ign

International audience; Aerodynamic drag reduction is needed to develop future fuel efficient ground transportation vehicles. Our study targets bluff bodies with wake asymmetries due to natural bistability or cross wind contributing to the drag incre

The three-dimensional near wake of a square-back bluff body in ground proximity is experimentally perturbed by placing a pair of D-shaped obstacles under the body. Five obstacle widths $d$ , from 12 % to 26 % of the height of the body, are used to pe

Combinations of passive and active flow control are used to reduce the aerodynamic drag of a three-dimensional blunt body by manipulating its large-scale wake asymmetries. An Ahmed-like body with a square-back is mounted in ground proximity in the te

Flow control experiments on a NACA 0015 airfoil using pulsed vortex generator jets (PVGJs) are carried out at a chord-based Reynolds number of $$4.6 \times 10^5$$ . Configurations of partially separated flow over the airfoil are studied with a specia

Flow control experiments using pulsed vortex generator jets (PVGJs) are carried out to improve the performance and maneuverability of a NACA 0015 airfoil. The analysis, which is mainly provided for fully separated flow fields in the literature, is ex

A combination of passive and active methods is used to manipulate the symmetry of the turbulent wake of an Ahmed body. Dedicated experiments to study the wake reversals occurring between symmetry-breaking states are performed. We show how transient s
