Modelling of Orifice Flow in Complex Thermodynamic Cycle Simulations
Šolín P.
pages 257 - +8p, full text

The present paper is aimed at the modelling of compressible gases in axisymmetric pipes exhibiting sudden changes (discontinuities) of diameter. These parts of pipes are called orifices. The modelling of orifice flow is problematic due to its complicated and genuinely spatial character. Moreover, due to the fact that the presented flow problem builds only a small part of a complex thermodynamic cycle simulation, we are requested to get satisfactory results using only as few degrees of freedom as possible. We develop several simplified models of the orifice flow and test their quality numerically. Results of numerical experiments are presented and discussed.
