Dynamics of direct spring operated pressure relief valve attached to pipeline:
from Computational Fluid Dynamics to spreadsheet computation
The presentation focuses on
the dynamical behaviour and stability of a 1 DoF oscillator (pressure relief valve) attached to an inlet
pipeline and an upstream reservoir. After systematically simplifying the
corresponding fluid mechanical equations we present a reduced order model
(quarter-wave model) capable of capturing the core dynamics. By means of
multiple timescale analysis, we present a criteria for
stable valve operation. It is shown that the impact of the valve body with the
seat gives rise to non-smooth grazing and impacting bifurcations. In particular, we present the two-parameter continuation of
grazing periodic orbits embedded into Matlab
environment.
The talk is held in Hungarian!
