Overview
This course covers Theoretical and
Applied concepts in Computational Aeroacoustics (CAA) using OpenFOAM, touching
on progressive Multiphysics design challenges, e.g. Aero-Vibro-acoustics (AVA).
In the practical part of the course, we will see how to use acoustic analogy,
how to prepare and set up the case to resolve the air-born sound.
Post-processing leading to noise characteristics is explained and tested.
An experienced trainer from OpenCFD – the company delivering official distribution of OpenFOAM every 6 months - will be presenting practical training based on the latest release. Training is based on mixture of lectures and hands-on exploring simple applications run on a cloud computer. More information can be found at https://openfoam.com/training/aerospace.php
Learning Objectives
- Understand spatial and temporal considerations (mesh and time-step)
- Noise Propagation to the far-field using acoustics analogies, e.g. Curle
- Understand the boundary condition choices and application of the damping zone
- Learn to operate spectral postprocessing using the built-in OpenFOAM point-based and surface-based temporal-Fourier analysis tools
- General hints and best practices to the CAA application with OpenFOAM
The Aeroacoustics course is suitable for existing users of OpenFOAM seeking to broaden their knowledge of OpenFOAM in the area of ACC. The Course is designed to impart important background knowledge to be able to use OpenFOAM effectively. The aim of the training is not only to show how to use OpenFOAM but as well to explain how it works to help users understand the choices they make on meshing, numerics, and boundary condition setup with respect to the desired results.
