Aerodynamic simulation of the LAGOON 1 landing gear using ProLB - Wall pressure fluctuations

Pressure fluctuations recorded on the surface of the LAGOON#1 Landing Gear. Mach number = 0.23 Re_D= 1.541 x 10 (Reynolds number based on the wheel diameter D = 0.3 m) High-frequency recordings enable accurate spectral analysis and a deep insight into the aerodynamically-generated noise sources.

The simulations are performed using ProLB, a software suite based on the lattice Boltzmann method (www.prolb-cfd.com).
