Hello COMSOL community,
I am trying to do a transient simulation of an accumulator in a hydraulic circuit. For simplification, the accumulator shall be placed as a bubble of a second fluid domain inside the domain of the hydraulic oil circuit. The bubble shall not mix up with the hydraulic oil domain and it shall not move. But of course, it must be deformable and the density of the bubble needs to be dependent on the surrounding pressure. Also, the E-module of the accumulator bubble needs to be considered.
Has anyone done a similar simulation or can give me an idea how to start? I'm not sure wether I have to use an additional structural mechanics physic for the deformation for the bubble and a moving mesh physic, or if I can simply use one fluid flow physic with two fluids.
Thank you for every kind of idea!
