Author Affiliations +
The inward flow piezo poppet valve (PZP) is examined by the use of CFD (Computational Fluid Dynamics) over a range of displacements and pressures consistent with the use of an actuating piezo driver, for conical head poppets in steady flow conditions. No tendency to unsteady fluid forcing of the poppet is seen in the computational output. A simple sizing technique is indicated.
