Deeltjes modellen voor de simulatie van transportprocessen: Particle models for the simulation of transport processes

Dubbele bachelor TECHNISCHE WISKUNDE en TECHNISCHE NATUURKUNDE - Het gebeurt regelmatig: ongelukken met schepen waarbij grote hoeveelheden olie vrijkomen. De gevolgen voor het milieu bij dit soort rampen zijn immens. Het is van groot belang dat er goede methoden zijn die kunnen voorspellen hoe deze olievlekken zich verspreiden. Een veel...

Prediction of emissions from combustion systems using 0D and 1D reacting flow models

Emission prediction is a complex problem involving the coupling between the flow field and chemistry. Most of the time CFD is the preferred modeling approach, yielding predictions with varying degrees of accuracy. But because of a high computational cost, CFD investigations are often limited to the use of reduced chemical mechanisms. In this...

Computational Modeling of Turbulent Ethanol Spray Flames in a Hot Diluted Coflow using OpenFOAM

Spray combustion finds a wide range of application in gas turbines, internal combustion engines, industrial furnaces, etc. In turbulent spray combustion, liquid fuel is injected into the combustion chamber in the form of droplets. In order to improve the combustion efficiency and to reduce the thermal NOx emissions released during combustion,...
