SOLIDWORKS Flow Simulation 2017 SP 3 introduced the capability of noise prediction. This allows the user to estimate noise generated by turbulent flow. Two new result parameters are now available – Acoustic power and Acoustic Power Level.
SOLIDWORKS Flow Simulation uses the Proudman formulae for the noise prediction calculation. It allows for the estimation of broadband noise that turbulence generates. The assumptions made in the Proudman derivation are as follows (see Fig. 1):
- High Reynolds number flow
- Low Mach number flow
- Isotropic turbulence
- Zero mean motion
