| 1. | A laser to measure noise - Zoom in the Lab |
| | In addition, the sensors disturb the air flow, thus modifying the noise.... However, knowing the acoustic pressure isn't enough, we must combine these measurements with a model of the wave propagation in the air flow, that is to say, an aero-acoustic propagation model. "... " So both the air flow speed and the acoustic speed related to the sound level can be measured at the same time, this with an unrivalled flexibility. "... |

| 2. | " Two in one " calculations - Materials for engines - Zoom in the Lab |
| | Temperature calculation of a turbine blade where the wall and a cooling channel are taken into account, with coupling of " fluid " and " solid " software (Cedre and Abaqus resp.). The air deforms the structure of an aircraft, while the aircraft's vibrations modify the air flow.... The air flow deforms the wings, causing vibrations, which in turn modify the fluid flow.... |

| | Even though all the real air flows can not be represented in a wind tunnel (we do not know how to represent a twisted sheet or the ship's swell motions), all these measurements are essential for getting a better understanding of the air movements and their consequences.... Topology of the air flow on the ship's surface.... |

| | Here, the gas is given and it is necessary to deal with the air flow.... Studies were done on a specifically developed test bench (CHYPRE bench), made up of a conduit of 5 cm x 10 cm sections, which combines three functions, creation of plasma, generation of air flow (0 v 150 m / s) and propagation of an electromagnetic wave (around 2 GHz).... |
