Numerical Simulation on Aerodynamically Generated Injection Nozzle Noise

Abstract:

In contrast to computational aerodynamics, which has advanced to a fairly mature state, computational aeroacoustics (CAA) has only recently emerged as a separate area of study. The fluid field when air flowing through the nozzle is calculated based on the standard RNG turbulent equations. The mass flow rate is tested based on the experiment. Comparing the calculated and tested mass flow rate, there is only 0.6% error. Hence the results based on the CFD method are reliable and can be used to industrial applications. The Lighthill’s acoustic analogy method is adopted and the noise when air poured into opens space is simulated. The noise is also tested by the experiments. The result indicate that the simulated data have the same tends as experiment data. Although there are some differences between the simulated and tested data, the simulated data shows that the numerical method can be qualitatively predicting the industrial noise.
