Simulation of Supersonic Jet Screech Noise using Direct Computational Aeroacoustics (CAA)
In this tutorial, we provide guidelines for modeling and simulation of a Supersonic Jet Screech Noise generated by an axisymmetric supersonic jet. We use direct computational aeroacoustics (CAA) in ANSYS FLUENT.
You will also learn how to do the following through this tutorial:
- Modifying constants for free jet flow in realizable k-e turbulence model and conducting axisymmetric simulation of a steady-state supersonic jet flow
- Finding the solution with direct CAA and using unsteady realizable k-e turbulence model and calculating unsteady flow and acoustic near field
- Saving acoustic data at nearfield microphone
- Also, post-processing and analyzing the flowfield and aeroacoustic results
Supersonic jet noise contains following components.
1- Broadband shock-associated noise.
2- Turbulent mixing noise.
3- Screech tones.
Here we model turbulent air flow. The cold jet has Mach equal to 1.2 and exits from 1” diameter round nozzle with 0.625” thick lip. We obtain nozzle geometry and flow conditions from experiments performed by Ponton and Seiner.
