Macroscopic traffic flow modelling
Pidrová, Kateřina ; Opluštil, Zdeněk (referee) ; Kisela, Tomáš (advisor)
This bachelor thesis is focused on macroscopic traffic flow modelling. First, we present a short introduction into the topic and basic model classification. Then we derive the continuity equation for macroscopic models and outline possible constitutive relations for a flux which determine the key features of the model. The main part of this work is focused on LWR model and its solution by the method of characteristic curves, with emphasize on shockwave creation. The thesis is concluded by an example and experiment comparing of the LWR model with real traffic on highway.

Analyses Of Static Pressure In Oblique Shockwave On The Probe Tip
Jenáček, Jakub
This article deals with the debugging analyses of Ansys Fluent for supersonic flowanalyzes. It is about analyzes on which the debugging of Ansys Fluent was made for analyzes ofsupersonic flow circumfluent the tip of the probe compared with the theory of isoentropic onedimensionalflow as a basic step for further analyzes in low pressures. The results shown in this paperwill further serve as a basis for experimental measuring of given problem.

Supersonic Flow Measurement Within A Lowpressure
Area
Bayer, Robert ; Hlavatá, Pavla ; Bílek, Michal
The goal of this paper is to describe the idea of measuring a supersonic gas flow within low-pressure areas in order to describe its behavior and to compare the measurement data with the generally described supersonic gas flow behavior derived from its behavior within high-pressure areas. This data should help to make low-pressure supersonic flow simulations more accurate.

Design Of The Shape Of The Experimental Chamber For The Analysis Of The Pressure Layout In The Differential Pumped Chamber
Hájková, Věra
This article is based on a study of Dr. Danilatos, where pumping of the differential pumped chamber is solved using the Monte Carlo statistical method. Similar results were obtained using the Ansys Fluent system. Theoretical computations as Dr. Danilatos and comparative studies are performed on theoretical shape. Simulations were made to obtain the shape of an experimental chamber with complete pumping shapes so that its shaping and pumping would ensure such a flow of gas to ensure the same distribution of pressure in the experimental chamber in the area under investigation as in the theoretical shape.
