Improvement of the numerical framework for selective catalytic reduction applications

The focus of this work is improvement and validation of the mathematical framework of commercial computational fluid dynamics code Fire for describing selective catalytic reduction processes. First step was further development of existing model for heat conduction inside the solid by enabling multilayer simulations, in order to have more accurate temperature profile and therefore more accurate heat transfer. Validation was carried out on the wellestablished experimental results from PhD thesis of Felix Birkhold. Furthermore, 3D numerical simulations of UWS injection in hot flue gases was conducted with the aim of determination of new set of parameters for urea thermolysis reaction rate.
