How to get oscillatory motion of fluid inside a pipe

Please login with a confirmed email address before reporting spam

Hi,

I am new to COMSOL and I am trying to model an oscillatory motion of the fluid inside a pipe. For the ease of computation, it is assumed that the pipe is filled with just the liquid. In reality, it is a multi-phase flow having pipe space half filled with liquid and rest with vapor. I want to know how can I get the fluid to oscillate with a certain oscillating frequency? What can be the inlet and outlet conditions to get the oscillatory motion?
I am trying to give pulsating pressure conditions at the inlet and outlet. But I am not sure how can I get the exact wave form in this case. Any input in this regard is appreciated.

Thanks.
