Inner geometry optimization of flat-panel photobioreactor
Hlaváč, Ivan ; Babička Fialová, Dominika (referee) ; Rebej, Miroslav (advisor)
This master thesis focus on optimatization of flat-panel photobioreactor. The optimatization was performed using CFD models and Design of experiement. The CFD model used for the optimatizaion was before performing the experiment validated with real experiment data. Hydrodynamic parameters affecting microalgae yield were monitored during CFD calculations. They were: gas holdup, gas velocity, turbulent kinetic energy, dead zone ratio. interfacial area and shear stress.The photobioreactor with a stirrer and with vertical baffles, which were selected based on research, were compared. The higher values of hydrodynamic parameters were reached with a stirrer. Baffels were evaluated as more suitable for microalgae, which are more sensitive to shear stress.

Combined heat and power generation
Hlaváč, Ivan ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
The bachelor thesis deals with the power generation by means of a combined gas-steam cycle. In the first part of the work, an overview and description of the combined cycle as well as of the Brayton cycle and the Rankine cycle are provided. The second part of the work focuses in the thermal analysis of the cycles. As a part of the work, a computer program was created, which allows for such thermal analysis of the combined cycle.
