Aerothermal flows

CFD Team is involved in aerothermal flow modeling of aircraft ventilation towards several cooperations with AIRBUS France Toulouse and ONERA-CERT (MAEVA II and ASTHER). Our principal aim is to enhance the understanding and the prediction of the aircraftÕs thermal environment to deal with the problems of composite materials. Indeed, for an identical mass, these materials are more resistant than the materials they replace. However, they are also more sensitive to the temperature variations and may age prematurely under extreme conditions.

We are currently investigating three classes of problems: the impact of a hot jet on a cold wall (film cooling), the convection problem appearing in cavities (nacelle ventilation) and the interaction of a hot jet in crossflow (JICF) on a cold wall (anti-icing system). Our purpose is to assess Large Eddy Simulation (LES) in order to reach complex industrial configurations. Only these type of unsteady simulations are able to take into account flow thermal instabilities by solving for large flow structures while modeling the small-scale effects.
