Aerodynamic simulation of the LAGOON 2 landing gear using ProLB Vortex shedding

Flow vorticity colored by velocity in the vicinity of the LAGOON#2 tow bar.
Mach number = 0.23
Re_D= 1.541 x 10 (Reynolds number based on the wheel diameter D = 0.3 m)
Vortex shedding due to the flow over the tow bar can be observed. This leads to tonal noise generation.
The simulations are performed using ProLB, a software suite based on the lattice Boltzmann method (
