Experimentální a numerické řešení hydraulického rázu užitím programu SimHydraulics

Abstract

The thesis analyses an experimental and numeric solution of a hydraulic impact. The introduction explains the principle of a hydraulic impact occurrence and the methods of its calculations. Based on experimental measurements a simulation circuit for a numeric solution of a hydraulic impact was defined in the SimHydraulics programme. The proposed simulation circuit is modified for three different blocks representing a hydroelectric generator in SimHydraulics. The dynamic courses of pressures received through the simulation were subsequently compared with the experiment. Based on the assessment of the dynamic courses of pressure the optimum simulation circuit was received, with an element representing a hydroelectric generator, to simulate a hydraulic impact.
