Metody simulace hydraulického rázu - vícefázové proudění

Abstract

This master thesis deals with methods of hydraulic shock simulation in the low-pressure hydraulic system. At the beginning of the work is described the problem of compressibility of liquids, namely the influence of air content and the modulus of fluid elasticity. Further, the theory of hydraulic shock is introduced and the methods of researches were specified. The circuit on which the measurements were made and the results of the measurements are described in the next chapter. Subsequently, mathematical models for hydraulic simulation were developed in the Matlab SimHydraulics and ANSYS Fluent programs. In the last part of the master thesis are measured results compared with the mathematical models.
