Flow in the non-return flap

Abstract

The essay concerns issues connected with modelling of flow in a non-return flap and determination of force effects on the flap disc. The task was researched in collaboration with ARMATURY Group, a.s. The flow is on-compressible and the flow medium is water. Boundary conditions determined by a measurement were applied in the modelling.The target of the project is finding a suitable mathematical model and comparison of the measured and calculated values dissipation factor of the non-return flap for various opening angles of the flap disc.
