Hydraulic analysis of the Damnice water supply system
Bergerová, Marie ; Kopecký, Josef (referee) ; Ručka, Jan (advisor)
This thesis deals with hydraulic analysis of the proposed concept of connecting the Damnice group water supply systém to the Znojmo group water supply system. In firt part, the issue of drought and the related threat to the supply of drinking water are presented. The second part is focused on the basics of mathematical water supply network modelling and software program EPANET 2.2 used for modelling is described. In the practical part, the focus area is characterised and the process of building the model in EPANT 2.2 is clarified. A hydraulic analysis was processed for simulating four variants that represented the connection of different count of unicipalities to the proposed group water supply system. For individual variants, the optimal pipe dimension of the main supply pipe as well as the branching water pipes along the route were sought. In processing the results of the hydraulic analysis, pressure ratios, flow rates, water age in the water supply network and the reserve capacities of the water tanks were assessed.
Stochastic modeling of water consumption in the water supply network
Kopecký, Josef ; Tureček,, Jan (referee) ; Ručka, Jan (advisor)
This thesis deals with stochastic water demand modellling in the water supply network. In the opening section, a research is created, where two different approaches to stochastic modelling of water consumption are presented. The practical part describes the creation of a deterministic hydraulic model and its calibration. Generated stochastic water demand patterns with a small time step of 1 minute, are then inserted into this model. Each household is assigned with a unique water demand pattern. Then a hydraulic analysis was done. A comparison of deterministic and stochastic approaches is presented at the end of the thesis. The comparison shows, that small-time step modelling does not have a big impact on the pressure ratios in the water supply network, but has a huge impact on the maximum flows and speeds occurring in links of the hydraulic model.
Hydraulic analysis of the Velký Beranov water supply network
Kopecký, Josef ; Remeš,, Bronislav (referee) ; Ručka, Jan (advisor)
The thesis is focused on hydraulic analysis of water supply network of the Velký Beranov in Jihlava district. A detailed quasi-dynamic hydraulic model of the water supply network was created, and then subsequently calibrated and verified on the basis of measurement of hydraulic quantities on the water supply network. The least squares numerical method was used to calibrate the model. The simulation model illustrates behavior of the water supply network during the characteristic operating conditions of the water supply. The follow-up analyzes carried out assessment of the pressure ratios with respect to the existing and future development given by the zoning plan.
Chassis of trailer bus
Kopecký, Josef ; Černý, Jan (referee) ; Píštěk, Václav (advisor)
My diploma thesis is about project trailer bus for transportation of persons. It´s for SOR Libchavy spol. s r.o. This project work deals with four-wheel trailer bus for person transportation with independent suspension of all wheels and air axle suspension. All of the wheels are operated in dependence on turning trailer drawbar. Both of the axles are taken from front axle of bus SOR BN 12.
