Wind-tunnel at Meudon

Wind-tunnel at Meudon

  • 1 Understanding the Turbulence that Causes Jet Noise

    For the first time, in the ONERA R4Ch wind-tunnel at Meudon, a series of PIV (Particle Image Velocimetry) data acquisitions was carried out at a high rate (2500 images per second), in the R4 Wind Tunnel at Meudon. With the stereoscopic installation it has been possible to measure the three components of the velocity in a plane transversal to the flow, thus allowing experimental access to the large scale dynamics of turbulence

    This picture was taken in Onera's R5Ch blow down windtunnel at Meudon. The hypersonic flow, coming from the left side, is Mach 10 (~1 5 km / s)
