Heat transfer solution of solidifying steel system with phase change with moving edge conditions
Fedorko, Tomáš ; Mauder, Tomáš (oponent) ; Štětina, Josef (vedoucí práce)
The master's thesis aim is to develop a 2D numerical slice model with moving boundary conditions of real geometry of caster in MATLAB environment. The model deals with a high non-linearity of the thermo-physical properties of steel during solidification and cooling. Not only the non-linearity of thermo-physical properties, but also the non-linearity during phase change is handled and simulated. Phase change is modeled by enthalpy method, effective heat capacity method and temperature recovery method. In the end, comparison of different approaches from the perspective of accuracy, speed of the computation and suitability of time discretization for non-stationary problems and parallelization is derived.

Optimalizace pro inženýrský návrh
Fedorko, Tomáš ; Mauder, Tomáš (oponent) ; Popela, Pavel (vedoucí práce)
Táto bakalárska práca sa zaoberá problematikou optimálneho chladenia tyče vzhľadom k nákladom spojeným s chladením. Popisuje problém vedenia tepla, jeho analytické riešenie, numerické riešenie okrajového problému a jeho implementáciu vo výpočtovom softvéri MATLAB funkciou FMINCON, kde jednotlivé výsledky sú graficky i výpočtovo zhrnuté a interpretované.
