Aerodynamical and acoustical optimization on industrial products
1. flow decomposition, to identify vortices that cause acoustic sources due to aerodynamic disturbances.
2. shape optimization, with rapid learning techniques, to reduce the energy losses caused by large vortices.
TourbillOnde is a startup created by Philippe Gilotte, to use these new methods, already validated in the automotive industry, on external aerodynamics applications, at OPmobility’s R&D center in the Lyon region, in partnership with the M2N laboratory of the CNAM Paris.
This approach can be applied to the optimization of the shapes of:
> aircraft near inhabited areas of airports,
> boats and submarines,
> fan blades, compressors, turbines, propellers, wind turbines,
> engineering structures subject to currents or winds.

Fluctuations in the velocity field around a vehicle, obtained with fluid mechanics software, using the Lattice Boltzmann method with an LES model.
Geometric changes to certain body elements can reduce the area where vortices are created.
Thanks to Altair’s numerical simulation tool and Friendship Systems‘ shape optimization tools, TourbillOnde offers the creation of substitution models linking geometric parameters to optimization objectives, in order to adapt the shape of products to their different conditions and usage stresses.
The company is located in the Community of Communes of the Plaine de l’Ain and benefits from its support in terms of innovation for its seed phase.
