Fan Tone Noise Prediction

Overview

Wondering if you can reduce an annoying tone from your fan?  Analysis from one of the NASA Glenn Acoustics Branch Fan Noise Prediction codes may help you.

BASS

The BASS code is a high-accuracy parallel computational aeroacoustics code which solves the Euler and Navier-Stokes equations to directly predict unsteady ...

V072

Predicated on simplistic models of the fan flow and geometry, V072 has been proven useful in studying rotor/stator interaction tone noise. When you need to ...

TFaNS

Taking rotor/stator interaction noise prediction to the next level, not only can TFaNS calculate the tone noise levels generated by rotor/stator ...

Linflux

When simple models are too simple, an analysis with Linflux gives you the power to study realistic, 3-D flows and blade geometries. Compared with V072 and ...
