Modeling Flow-Acoustic Interaction in COMSOL Multiphysics®
Duration: 44:35
In this archived webinar, learn how to model flow-acoustic interaction using the linearized Euler and Navier-Stokes physics interfaces in the Acoustics Module, an add-on product to the COMSOL Multiphysics® software. Topics include predicting the acoustic behavior and performance of liners and perforates, modeling fluid-structure interaction problems in the frequency domain, and analyzing combustion instabilities. You also get a demonstration of how to model flow-acoustic interaction in COMSOL Multiphysics®.
