Abstract

Diese Arbeit befasst sich mit der numerischen Modellierung von monolithischen Autoabgaskatalysatoren unter Berücksichtigung verschiedener Transportmodelle in Gasphase und poröser Washcoatschicht sowie heterogener Reaktionsmechanismen, die auf Elementarreaktionen aufbauen. Hierbei wird der Einfluss mehrerer Modellparameter auf die Schadstoffumsätze im Katalysator mit Hilfe des Softwarepakets zur Simulation reaktiver Strömungen DETCHEM untersucht.

Abstract

Fluid mechanical problems related to two-layer flows are of considerable interest in a variety of geophysical, atmospheric and engineering contexts. A two-layer counter-current flow system over a submerged sill is investigated. The effect of higher Reynolds numbers and of enhanced bottom roughness on the generation and development of hydrodynamic instabilities between the two layers are investigated by means of physical experiments and linear stability analysis.

Abstract

Soot formation in a laminar and a turbulent diffusion flame as well as the formation of iron oxide nanoparticles in an iron pentacarbonyl doped near stoichiometric H?/O?/Ar-premixed flame have been investigated numerically. The particular modus operandi of the simulated test cases is described. In the case of the turbulent flame the impact of the turbulent closure of the single particle source terms on particle size distribution is shown.

Abstract

The analysis of turbulent mixing in complex turbulent flows is a challenging task. The effective mixing of entrained fluids to a molecular level is a vital part of the dynamics of turbulent flows, especially when combustion is involved. The work has shown the limitations of the steady-state simulations and acknowledged the need of applying high-fidelity unsteady methods for the calculation of flows with pronounced unsteadiness promoted by large-scale coherent structures or other sources.
