Methodic of vertical deflections determination of bridge construction by the radar interferometric technology
Antoš, Filip ; Talich, Milan ; Glöckner, M. ; Böhm, Ondřej ; Soukup, Lubomír ; Havrlant, Jan ; Závrská, M. ; Šolc, Jakub
The methodology provides guidance for determining the vertical deflection of bridge structures using radar interferometry technology. The vertical deflection of bridges are primarily caused by stress during transit of vehicles. The deflections are simultaneously measured by radar throughout the length of the monitored structure. The measurement is continuous with a high sampling frequency (200 Hz) and with high precision (0.01 mm). It is believed the use of interferometric radar IBIS-S Italian manufacturer IDS. General recommendations and conclusions are valid for every kind of radar.
Analysis of the Fluid Flow in Pipes Circular and Not Circular Cross-Section With Methods Using Distribution of the Vorticity Density
Soukup, Lubomír ; Kozubková, Milada (referee) ; Matas, Jakub (referee) ; Štigler, Jaroslav (advisor)
The doctoral thesis deals with the analysis of the flow in the circular and not circular cross-section pipes by methods using the distribution of the vorticity density. This analysis is particularly focused on the derivation of the new velocity profiles formulas using the above mentioned method. In this work is presented a historical overview of the derived velocity profiles. This overview of already derived velocity profiles will be a fundamental benchmark for newly derived velocity profiles. These new velocity profiles are derived for the circular and not circular cross-section pipes and the derivation is based on the analogy of electromagnetic induction by using Biot-Savart law. It is necessary to apply this analogy at first on solitary vortex filament. By taking this step is possible to get the value of the induced velocity from one solitary vortex filament. Subsequently it is possible to obtain the value of the induced velocity from the vorticity wall and afterwards from the vorticity density distribution over the cross section. This work contains also the results of the experimental measurements of the velocity profiles, and of the CFD simulations. Experimentally measured results are used besides other for the selecting of the most suitable CFD computational model. Selected CFD model will be subsequently declared as a reference model and the valid velocity profiles for this model will serve with the experimentally measured data as a benchmark for the newly derived velocity profiles.

Methodics of horizontal movements determination of height objetcs by the radar interferometric technology
Antoš, Filip ; Talich, Milan ; Glöckner, M. ; Böhm, O. ; Soukup, Lubomír ; Havrlant, Jan ; Závrská, M. ; Šolc, Jakub
The Methodics provides a user with an instruction for horizontal movements determination of height objetcs by the radar interferometric technology. The horizontal movements of height objetcs are roused by the weather conditions or by the object fundament instability or by influence of intrinsic forces caused by a mechanic component attached to the object. The movements of the height objetcs are measured simultaneously in the whole length of the monitored object. The measurement is continuous with high frequency (up to 200 Hz) and very precise (up to 0,01 mm). It is possible to measure remotely, without need of accesss to the object, when natural reflectors of radar signal are parts of the object's surface. If the body of the object, resp. attached metal parts have poor reflection, metal corner reflectors have to be attached to suitable places on the object. Interferometric radar IBIS-S of Italian production is supposed to be used. Nevertheless, the general recomendations and conclusions are valid for any other radar device of this kind.
Utilization of the greywater
Zríni, Miroslav ; Soukup, Lubomír (referee) ; Štigler, Jaroslav (advisor)
The bachelor work consists of two parts. First is the theoretical research about waste water of household. Due to the different features of the water, it is divided into greywater and rainwater. In each section are mentioned properties, quality needs, cleaning method and others. Concrete utilization of these waters is illustrated on the recycling system by company Asio. s.r.o. Last chapter deals with heat recovery of the greywater. Second, the practical part is aimed at proposal of a small recycling unit in certain location. It includes proposal of a storage tank, selection of a pump device or water station and any necessary accessories. The end is concluded with financial balance-sheet of the project.
The force of water jet on a flat surface
Kasal, Milan ; Soukup, Lubomír (referee) ; Fic, Miloslav (advisor)
This bachelor thesis discusses about the theory of fluid mechanics. In the first part of work are listed the basic hydrodynamic laws for ideal and real fluid. Further there was derived force acting on the surface. The second part is devoted to the practical use of force water jet to generate electricity and cutting of material. The objective of the last section, was practical verification of derived relations during laboratory measurements.
Pressure losses and heat output of the hydraulic blocks of a linear integrated hydraulic unit
Soukup, Lubomír ; Červinka, Martin (referee) ; Klas, Roman (advisor)
A common problem in the design of hydraulic systems is the pressure losses caused by movement of viscous liquid in individual elements of hydraulic circuits. These losses have negative effects on the overall efficiency of hydraulic systems and thus their overall operation. There is a change in temperature of working fluid and components (elements) of circuit due to the result of the mentioned losses. This master thesis is focused on the heat generation (output) in hydraulic cubes of a linear integrated hydraulic cubes (here in after LIHJ) which is the prototype of hydraulic lifting equipment. Losses, arising during the operation LIHJ in pipes and in hoses, can be determined numerically and experimentally. Most of hydrostatic transmitters and others hydraulic components are almost always supplied with the necessary documentation which contains all the necessary information such as experimental characteristics, etc. However problematic parts are the hydraulic blocks which are specific to their size and function. Of course, each manufacturer must prepare technical documentation including characteristics which are important for trouble-free operation of the hydraulic system. The main aim of this work is to determine pressure losses and the heat generation (output) in the hydraulics blocks by program which is used for creating geometry and computing using software like Ansys Fluent, which is based on the finite element method. If these calculations could be compared with experimental measurement technically, then heat generation (output) in both the cubes will be evaluated towards other hydraulic components and the whole system (device). The simulation results will be implemented in software which is used for calculation of heat generation in LIHJ at different operating modes and loads. Furthermore, these results will be the basis for the design of geometry of hydraulic blocks with low pressure losses which will reduce energy consumption of the device. At the end of this thesis, some advanced methods for the manufacturing of hydraulic blocks are briefly introduced, namely the method 3-D casting.
