Function of surge chamber
Březina, Michal ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
The thesis is focused on creation of the mathematical model for calculating the change of fluid volume and flow in surge tank and air chamber during the water hammer effect. The work also includes the derivation of the basic equations of hydrodynamics and the theory dealing with water hammer including the possibilities in protection of the pipeline system during this phenomenon.

Innovation of the laboratory stand Water jet
Šimůnek, Petr ; Rudolf, Pavel (referee) ; Hudec, Martin (advisor)
The subject of this bachelor's thesis is the design of a new experimental device for measuring the force of a water jet on various shaped surfaces. The first part of the work is focused on the theory around the task. The second part deals with the parts of the device. And in the third part is carried out exemplary calculation.

Water hammer theory
Šíblová, Kamila ; Habán, Vladimír (referee) ; Fialová, Simona (advisor)
The thesis is a well-arranged text, which deals with the theory, solution and use of water hammer. For solution is used the method of charakteristic, the Lax-Wendroff method and the methods of FTCS. The thesis is a synthesis of all available information about the watter hammer and its use in practice.

Pressure drop determination of the charging pump in the water level oscillation dependence
Sůkal, Jaroslav ; Hudec, Martin (referee) ; Fialová, Simona (advisor)
The bachelor thesis deals with basic equations of hydromechanics. The derivation process of Euler equation for hydrodynamics and Bernoulli equation is outlined. It also includes the analysis of the real liquids flow as well as the friction losses. The oscilatory motion in between two joint tanks is described. The phenomenon is solved by Bernoulli equation with an unsteady term. A part of the thesis treats the derivation process of the equation of the equilibrum surface deflection description and its simplified resolving. A model problem of the phenomenon is put forward.

Simple Rheoscopic Flows Used in Teaching Fluid Mechanics
Duda, D. ; Yanovych, Vitalii ; Uruba, Václav
Four simple demonstration experiments are presented. They are used as a support in the teaching of Fluid Mechanics I (a compulsory lecture at the University of West Bohemia in Pilsen). All mentioned experiments use the rheoscopic fluid obtained as a water solution of mica powder to visualize the flow in a esthetic way, which, as we hope, has a potential to attract students attention. The experiments are: demonstration of Bernoulli equation in a widening and narrowing channel, Taylor-Couette flow, the effect of viscosity to the scales and decay of turbulence, and the Galilean transformation inside an axial compressor.
