Etude expérimentale de l'interaction de gouttes avec un écoulement turbulent
Descriptif
The influence of rain on flows around vehicles is a new emerging theme at LMFL. A crucial aspect of the physics that determines both the mean drag and its fluctuations concerns the sharp and dynamic interface that exists in turbulent sheared flows between the turbulent and non-turbulent parts of the flow. An important aspect of the influence of rain is the interaction between droplets and this interface, and this aspect is in fact of more general importance as it is present in other situations (environmental dispersion, clouds, etc). The laboratory has strong expertise in PIV and turbulence and also has a planar jet and a droplet velocity, size and concentration measurement apparatus available for this study. The laboratory also plans to build a new wind tunnel specifically for aerodynamic studies in rainy conditions that will be integrated into the CONTRAERO platform. The mission of the post-doc will be to study and select the water droplet generation and injection systems and to use them for the experimental study of the interactions between droplets and the turbulence/non-turbulence interface. He will also assist in the implementation of the new wind tunnel and his project will be the first to benefit from it.
