Matematické modelování proudění v armatuře plynového rozvodu mobilního kontejnerového zařízení na stlačený zemní plyn (CNG)

Abstract

The thesis deals with the mathematical modeling of flow in the valve of the gas container facility on the divorce of a mobile compressed natural gas. The work is a description of an autonomous mobile device – the container ALFA. Then there is described the theory of flow, loss in the pipe system, expansion of the gas and the CFD modelling. In the next section are defined the operational boundary conditions on the basis of experimental measurements. According to the boundary conditions is defined by the mathematical model for CFD modeling (simulation) anisothermal flow in the valve. Evaluation of the results obtained is processed in the form of tables and charts.
