modelling of a piston

modelling of a piston

(OP)
Hi ,
To model a fluid chamber closed at one end, connected to a piston in 1D. I know that the piston can be modelled as a bar and I know the boundary conditions imposed as the boundary connected to the fluid. My question what the displacement (u) and velocity (v) and stress (sigma) are at the other end (not connected to the fluid). I would appreciate some quick responses.

RE: modelling of a piston

Hoomanya,

This sounds like either a fluid mechanics problem, or an FEA problem, possibly involving a specific software package. Try posting this to an appropriate forum.

RE: modelling of a piston

If this is an acoustic problem, then a nearing model could be the Helmholtz resonator with no neck...
