Gregor Schwarz: A Flexible Cartesian Grid Data Structure for Coupled Simulations

In computational fluid dynamics it is sometimes beneficial to couple different solvers within the same simulation. In this bachelor's thesis a parallel data structure based on Cartesian grids is developed that allows such a coupling. The focus of the data structure lies on its flexibility: the solvers can operate on different resolved Cartesian grids that are positioned arbitrarily in the computational domain and are scattered on different processors. In addition to that, solvers are allowed to have an arbitrary cell format. Due to the flexibility of the developed Cartesian grid data structure, the coupling of different solvers can be performed easily without the need for major adaptions to the code.

Markus Auer: Improvement of kinetic model for steam cracking furnaces

Steam Cracking is an important process for the petrochemical industry transforming saturated hydrocarbons at elevated temperature in the presence of steam into smaller unsaturated hydrocarbons, mainly for production of lighter alkenes such as ethylene and propylene, as well as butadiene and aromatics. In this master's thesis, simulation and optimization techniques of the open source CasADi framework shall be applied. The capabilities and applicability are to be demonstrated for steam cracking simulation. An adequate simulation model of the tubular reactor coil with a reduced set of chemical reactions shall be implemented. Simulation results shall be compared to measurement data. Additionally, mathematical parameter estimation techniques shall be applied for adaptation of the kinetic model to measured data.
