Vane pump
Poul, Josef ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
This bachelor’s thesis talks about the problems of pumps, especially vane pumps. After research part, there are given some basic relations for the design of the pump. Then there is calculation of the basic dimensions according to the given parameters. In conslusion, the designed shape is subjected to the CFD analysis.

Valve Exploiting Principle of the Side-Channel Turbine
Jandourek, Pavel ; Janalík, Jaroslav (referee) ; Varchola, Michal (referee) ; Pochylý, František (advisor)
The presented work deals with basic characteristics of the side-channel machines. The intention is to replace the pressure reducing valve by low-specific speed side-channel turbine. Thereby creating a kind of turbine valve using energy, which would otherwise be dissipated in the valve. Pressure reducing valves are the source of large hydraulic losses and their replacement is possible, because the same resistance characteristics side-channel turbine and a pressure reducing valve.

Screw pumps
Dvořák, Petr ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
This work gives basic information about screw pumps. The work is about hydrostatic convertors. It describes division hydrostatic convertors basic information, purpose, equations and diagrams. Then the work gives information about division of screw pumps, their construction, principle, how working and utilization. At the end of the work is derivation of equations for computation twinscrew pump with buttress thread and drawing of diagrams from these equations. Consequently is doing calculation of twin screw pump for entry data.

Fluid coupling
Vavrla, Zdenek ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
This diploma´s thesis deals in the first part with hydrodynamic coupling, mainly on her construction and function description. In the second part of this diploma´s thesis is solved influence construction changes of the hydrodynamic coupling to the transmitted torque. Changes in the construction are determined by changing the number of blades and changing the value gap between the turbine and pump round. Finally, construction change is solved of the hydrodynamic coupling to increase the transmitted torque and force effects are evaluated on the hydrodynamic coupling.

Study of turbine with side channel runner
Jandourek, Pavel ; Haluza, Miloslav (referee) ; Pochylý, František (advisor)
This thesis deals with proposal of constructional solving turbine with side channel. Basis for the design is lossy characteristics of the valve. The intention is to replace hydraulic closures by turbine with side channel runner. Hydraulic losses in the flow restriction in turn replaced by the electricity generation in the comparable characteristics of valve and turbine.

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.

Vane pump
Mach, Jiří ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
This work gives basic information about vane pumps, especially with unbalanced construction and vanes led by rotor. The first chapter generally gives an attention to pumps. There are described basic information, classification, advantages and disadvantages of the types, characteristics and calculation relations. The following chapters describe the vane pumps in the way of classification, description of function and calculation relations. There is also made a practical calculation of vane pump according to the assignment accompanied by CFD analysis.
