Dynamic behavior od rotor dynamics stystem vibrating in a liquid
Chlud, Michal ; Pochylý, František (referee) ; Malenovský, Eduard (advisor)
This thesis deals with dynamic behavior of swirl turbine vibrating in a liquid. Primarily is studied decrease of natural frequencies of rotor due the interaction with fluid environment, namely for different levels of submerged rotor in fluid. After that follows the detection of natural frequencies of swirl turbine in operating speed. The problem is solved by computational modeling in ANSYS system. For this solution is used acoustic elements method. The results are compared with experiment.
Interaction of steel tank structure with liquid during seismic event
Plášil, Pavel ; Hradil, Petr (referee) ; Salajka, Vlastislav (advisor)
Construction of structural computational model of the tank with fluid using program package ANSYS based on the Finite Element Method. Solve eigen-vibration of the tank with or without effects of fluid. Application of Euler and Lagrange method for modeling fluid. Solve seismic response using response spectra. Verify of the tank in accordance to EC 3 and EC8.
