Would it be possible to do a experimental setup where I create a dynamic pressure (10-500 Hz) of around 0.1-2 MPa, using a high force piezoelectric pushing on a piston on a Small volume of oil fluid.
There is this paper, where the authors create a pressure wave of around 170 KPa using a piezoelectric. I want to do something similar but with higher ∂P.
Well, I work on electronics, (energy harvesting) . So I need to provide a pressure disturbance to my test subject, the pressure amplitude should be around 0-2 MPa and the precision is not important. I can take 3-4 harmonics. I'll be sensing the pressure with a piezoelectric pressure sensor @ 5khz. I wanted to know if the ∂P will follow the relation of a compressible fluid : ∂P/B=∂V/V, where B: bulk modulus of the oil. Or it will follow another behaviour. I have zero knowledge in fluid dynamics, been reading about it, but cannot find a good answer. Thanks for the help
