4.6 Numerical Simulation of Flow-Field
in a Large Lowspeed Closed-Circuit
Aeroacoustics Wind Tunnel
4.6.1 Problem Description
The numerical simulation process and results of a large low-speed closedcircuit aeroacoustics wind tunnel are presented in this example. The incompressible N-S equations are used to calculate the full turbulent RANS
