Quantification of hydrodynamic load on overflowed bridge deck using 2D numerical simulation
Pavlíček, Michal ; Hrdlička, Libor (referee) ; Špano, Miroslav (advisor)
The diploma thesis is focused on a quantification of hydrodynamic load of overflowed bridge deck. Solution was pursued by using two–dimensional numerical simulation of open channel flow in vertical plane created in ANSYS 15.0 software (modules: Workbench, Design Modeler, Meshing, Fluent). Values of drag force, lift force, moment, drag coefficient, lift coefficient and moment coefficient is result of computation. Various types of bridge decks were tested in relation to the degree of inundation (inundation ratio) and flow velocity.The thesis provides comparison of numerical simulation with physical experimental testing and result published in accessible resources.

Determination of hydrodynamic load acting on overflowed bridge deck using numerical simulations
Stoklas, Jan ; Picek,, Tomáš (referee) ; Špano, Miroslav (advisor)
The subjekt of this diploma thesis is a quantification of hydrodynamic load of the overflow bridge deck using numerical simulations. The simulation was performe for eight different discharges, which correspond to different degrees of inundation of the bridge deck using different turbulent models in Flow-3D software. The result of the calculation are the values of the hydrodynamic load– the horizontal force, the vertical force and the moment acting on the bridge deck. Furthermore, drag coefficient, lift coefficient and moment coefficient were quantified. Finally, the results of turbulent models were compared with each other and with result of physical experimental testing.
