Abstract:
Abstract The recent development of Particle Tracking Velocimetry (PTV) for large-volume investigation in air has made this technique particularly well-suited to validate numerical simulations of complex aerodynamic configurations. At the same time, Large Eddy Simulations (LES) using high-order spectral h/p element methods have proven to be a powerful tool for investigating flows around complex geometries at high Reynolds (Re) numbers. In a recent study Liosi et al. [1] have successfully implemented this numerical methodology to analyse the flow behind a Formula 1 wing. However, the validation of their simulation was based on limited experimental data, mostly pointwise velocity measure, pressure surveys, or a limited number of PIV planes. In this work, the advantages of using volumetric PTV to validate numerical simulations is explored by presenting an experiment on the Imperial Front Wing (IFW) of the same geometry used by Liosi et al. [1]. The test was performed in the 10x5 wind tunnel over a moving ground (rolling road). Results show excellent agreement with the numerical prediction revealing new insights into the development of the vortical structures shed from the different wing elements. The work offers a unique dataset of significant value for the Formula 1 community. Extended Abstract attached.
