Vibrating Particle in Water — Correct Thermoviscous Acoustic Material Parameters

Application ID: 14723

This is a tutorial model that simulates a small vibrating hemispherical particle in water. The vibrations induce acoustic waves in the fluid. The model shows how to set up the material parameters in a thermoacoustic model to get the correct acoustic (compressible) waves in the fluid.
