Phase equilibrium curve of gas mixtures
Fúdor, Vlastimil ; Habán, Vladimír (referee) ; Himr, Daniel (advisor)
This thesis is focused on the construction phase diagrams of various gas mixtures. The properties of real gas mixtures are modeled by two equations of state. The simpler one is the Peng-Robinson equation of state. The more complex and accurate equation of state is the GERG-2004. Two methods are used to construct the phase diagram namely the successive substitution method and the Newton method. The numerical procedure has been developed in Python programming language. A zip archive of the developed program is an integral part of the thesis. This program solves gas mixtures consisting of nitrogen, carbon dioxide, methane, ethane, propane, n-butane, isobutane, n-pentane, isopentane, n-hexane, n-heptane.

Physical properties and combustion characteristic of fuels
Nejezchleb, Radek ; Skryja, Pavel (referee) ; Kermes, Vít (advisor)
The subject of this bachelor’s thesis is creating an open calculation tool for determination of elementary properties of gas fuels and calculation of basic combustion characteristics. The theoretical part is focused on chemical equations by combustion, basic equations for calculation of process in gases and calculation of heating value, explosive limits and Wobe index. The most used gas fuels are described furthermore. The next part of bachelor’s thesis is focused on oxidant, especially on the calculation of composition of moist air and mixing of air and oxygen. Equations for the computing of enthalpy of gases and adiabatic heating temperature are noted at the end of the theoretical part.
