Hello,
I am modeling the oscillation of a bubble in water subjected to an acoustic wave. I have successfully performed the analysis in the frequency domain, where I define the acoustic wave using pressure acoustics and couple the boundary conditions with thermoviscous acoustics. Within the thermoviscous acoustics physics, I have defined two domains: air and water. At the air-water interface, I have incorporated surface tension, allowing me to plot the displacement and mode shapes of the bubble.
However, when transitioning to a transient study, I notice that the thermoviscous acoustics module lacks a surface tension node. My current setup includes "Pressure Acoustics, Transient" and "Thermoviscous Acoustics, Transient."
How can I incorporate surface tension into this transient study and accurately measure the transient displacement of the bubble interface?
Thanks in advance! Ali
