Self-priming pump
Kusý, Jan ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
This diploma thesis deals with analysis and description of principles of self-priming pumps and description of physical processes, that allow self-priming. With these basements should be proposed innovation of construction for selected type of pump.
Study of plunger pump with linear motor
Machát, Pavel ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
The aim of this thesis is an engineering design of plunger pump with linear motor. This type of pump is used especially for blood pumping in heart surgery. The theoretical part is focused on distribution of pumps, description of extracorporeal circuit and booster heart history. There are basic calculations derived, which describe plunger pump performance. Then varied designs of plunger pumps follows, which are differed in size, shape and application. Next part includes design of reverse valves and their CFD computation.
Study of diaphragm pump with linear motor
Dubový, Ľuboš ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
The content of this master‘s thesis is a study of diaphragm pump with linear drive. Linear motor was used as the linear drive. Thesis is well – founded by theoretic calculation of pump and its design draft. Likewise, the thesis includes optimalization of suction, or pressure, valve for pump, created by using computer fluid dynamics software. Thesis is complemented by basic view of different types of pumps based on the classification by hydrodynamic and hydrostatic pumps. Subsequently, the preview of blood – flow pumps is presented.
Assesment of air concentration in water depending on pressure
Uttendorfský, Petr ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
This thesis deals with dependence of heat transfer coefficient on rate of air concentration in the water. Main idea appears from gas dissolvability in water depending on pressure, Henry's law and Newton's law of cooling. There had been an experiment made to verify the hypothesis.
Modulated ultrasonic water jet cutting – optimization of the liquid wave guide shape
Veselý, Radek ; Foldyna, Josef (referee) ; Habán, Vladimír (advisor)
High speed water jets have un-substitutable place in unconventional technologies in the machining of materials. Indeed its larger spreading is limited above all by its really high purchase price and also high costs of the operation. Certain possibility is represented by high-speed pulsating jets, which don’t put such a high pretension on arrangement of generating the pressure during the comparable operation. Probably the most effective method of the generating of pulsating water jets is ultrasonic modulation. This work could benefit to understanding spreading of pressure impulses between ultrasonic generator and output nozzle. Pulsating is solved by the numerical calculation using transfer matrix method.
Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.
Simulation and damping of the excited pulsation
Kubis, Aleš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design math and numeric system, which simulate these features: model of threeplunger piston pump, system of piping and damping elements. This thesis also contains chapters, which describing numeric models of particular’s elements of system with charts of function dependencies from computation’s program. The last chapter contains numeric model of treeplunger piston pump without damping elements. Continuation of my diploma thesis should be a harmonized of damping elements and designed pump.
Adjustment of the pumping station and delivery pipeline of the raw water to location of JETE for considered building up of new nuclear sources.
Hejný, Radek ; Mareška, Václav (referee) ; Habán, Vladimír (advisor)
The task of the diploma thesis ‚‚Adjustment of the pumping station and delivery pipeline of the raw water to location of JETE for considered building up of new nuclear sources‘‘ is to figure out a capability of the pumping station Hněvkovice to draw a sufficient capacity of a raw water to the Temelín nuclear power plant. In case of necessity, it designs useful adjustment of a pumping station and deliver pipeline for increasing the raw water delivery rate.
Modeling of flow in ejector
Bílek, Martin ; Habán, Vladimír (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis deals with the flow modelling in the ejector using the FLUENT software. It develops a diploma thesis created in the past, where a mathematical flow model in the ejector was created and experimentally tested. The aim of this work is to analyze the ejector calculations and to model a flow in an ejector of the same shape as in the experiment and under the same conditions, too. Another objective was to assess the influence of the throat length and to examine if the pressure in the ejector mixing chamber remains constant. Finally, the disagreement between the experimental figures and the ones gained from the mathematical model of the ejector are discussed.
Experimental verification of ejector and creation of mathematical model.
Strmiska, Michal ; Štigler, Jaroslav (referee) ; Habán, Vladimír (advisor)
This diploma thesis deals with the area of ejectors. In the intoduction, an ejector is classed as an hydraulic machine. There is also an introduction of the principle and application of this machine there. The next part describes two different ways of calculation and there is a suggestion how to get characteristics, that were achieved by calculation in MS Excel, projected. The purpose of this diploma thesis is to confront this mathematical model with the experiment done in school laboratory at Kaplan department of hydraulic machines. The description of this experiment and the evaluation procedure of measured values is described in the final part of this diploma thesis.
