Determination of fired heater heat duty
Slowik, Roman ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The compilation and application of a new alternative method of calculating the heat duty of process tubular furnaces, published in the journal Chemical Engineering Research and Design, is the main objective of this work. The alternative method is processed in a suitable computational environment and the created calculation tool is subsequently applied to the given industrial cases of process tubular furnaces. An assessment of the accuracy of the new alternative method is performed on the basis of a comparison of the results obtained from the industrial cases with available results from commercial simulation software.

CFD modelling of granular flow in rotary kiln
Slowik, Roman ; Vondál, Jiří (referee) ; Juřena, Tomáš (advisor)
This work deals with modeling the flow of particulate matter in rotary kilns. For this purpose, a combined CFD and Discrete Element Method (DEM) model was used. Using Ansys Fluent software, several simulations were performed in order to determine the mean residence time and movement of the material in the rotary drum dryer. Results of the computational model were used to develop a regression model of the mean residence time and compared to the values as given by empirical equations. Furthermore, a simplified sensitivity analysis was performed for the selected input parameters of the model such as the stiffness constant, air mass flow rate and the particle size.
