Modelling of flow over two transversal ribs in a channel with free surface
Sládek, A. ; Příhoda, Jaromír ; Stanislav, Jiří
Numerical simulation of turbulent flow over two transversal ribs on the bottom of a channel with free surface was carried out. The VOF (Volume-of-Fluid) method implemented in the commercial software FLUENT 6.3 was used for the solution of supercritical flow in a channel with free surface. The two-equation turbulence model according to Shih et al. was applied. The simulation was realised for ribs with the relative spacing t/b = 6; 10 and 20. Profiles of mean velocity and velocity fluctuation obtained by numerical simulation were compared with experimental data from LDA and PIV measurements. The behaviour of free surface over ribs was compared with experiments as well.
Entrerpreneur and his perception of risk
Stanislav, Jiří ; Lukeš, Martin (advisor) ; Schuster, Karel (referee)
This thesis is focused on entrepreneurial thinking and on the perception of risk of particular entrepreneurs. The introduction acquaints the reader with the thesis scope and contains descriptions of particular chapters. The thesis goals are also described shortly. The thesis is divided into two main parts -- a theoretical part and an applied (practical) part. The theoretical part includes entrepreneurial factors which influence entrepreneurial risk, a description of risk, and a risk analysis with respect to entrepreneurs` working and personal life. The applied part contains data analysis which was gathered during in-depth interviews with particular entrepreneurs. Analysis is drawn up based on the theoretical aspects.
