I've ask at work if anyone has successfully simulated flow noise and the answer was no. It may be necessary to use direct numerical simulation instead of a turbulence model to capture the pressure fluctuations, unless there is a way to back them out of k and epsilon, but I'm only hypothesizing.

Even DNS does not work, because the pressure fluctuations we call sound (what we can hear in the far field) are some orders of magnitude lower than the turbulent pressure fluctiations in the flow (sometimes called pseudo sound).

Hi
I am not gonna get involved with the "useless" discussion about the accuracy and performance of simulation software. If anyone has better software, he should come forward and compete in the market.

I am facing problem simulation hydrogen engine. The software cannot accept hydrogen as "Gaseous fuel.

If anyone can help i will be thankful. I got excellent performance compared with experimental using gasoline fuel with Ricardo E6/T Variable Compression Engine. I am now interested to do the same with hydrogen fuel.

Any suggestions Plz.

Best regards
