Silvestri, S. (author)Radiative heat transfer has a large influence in engineering systems, especially when the temperature involved is elevated. For this reason a correct assessment of heat transfer in presence of radiation is of great importance in high temperature and pressure equipment such as combustion chambers, heat exchangers as well as reentry vehicles and...doctoral thesis 2021

Huang, X. (author)The technique called "flameless combustion", also denoted as "MILD" combustion, was developed to reduce the nitrogen oxides (NOx) emission in the combustion process. The term "flameless" refers to the low visibility of the flame. The technique is particularly of interest when hot exhaust gas is used to preheat inlet air to high temperature. The...doctoral thesis 2018

Ma, L. (author)The objective of the research presented in this thesis is development and validation of predictive models or modeling approaches of liquid fuel combustion (spray combustion) in hot-diluted environments, known as flameless combustion or MILD combustion. The goal is to combine good physical insight, appropriate numerical methods and good software...doctoral thesis 2016

Correia Rodrigues, H.R. (author)Nitric oxides (NOx) are formed as a byproduct of combustion and contribute to ground-level ozone formation and the creation of conditions harmful for human health. In response to air pollutant emissions regulations, technologies for controlling NOx formation for a entire spectrum of fuels ranging from gaseous, liquid, coals, biomass and residue...doctoral thesis 2015

Xie, M. (author)The risk of explosion due to rupture of a tank filled with pressurized liquefied gas (PLG) is one of the risks to be considered in the context of studies on tunnel safety. When a vessel containing liquid well above its boiling point at normal atmospheric pressure fails catastrophically a Boiling Liquid Expanding Vapour Explosion (BLEVE) can...doctoral thesis 2013

Oldenhof, E. (author)This dissertation examines stabilisation processes in turbulent non-premixed jet flames, created by injecting gaseous fuel into a co-flowing stream of hot, low-oxygen combustion products. Being able to predict whether and how a flame achieves stable and reliable combustion is a matter of great practical relevance, and a challenging scientific...doctoral thesis 2012

Danon, B. (author)In this thesis three different combustion systems, equipped with either a single or multiple ?ameless combustion burner(s), are discussed. All these setups were investigated both experimentally and numerically, i.e., using Computational Fluid Dynamics (CFD) simulations. Flameless combustion is a combustion technology capable of accomplishing the...doctoral thesis 2011

High Frequency Combustion Instabilities of LOx/CH4 Spray Flames in Rocket Engine Combustion ChambersSliphorst, M. (author)Ever since the early stages of space transportation in the 1940’s, and the related liquid propellant rocket engine development, combustion instability has been a major issue. High frequency combustion instability (HFCI) is the interaction between combustion and the acoustic field in the combustion chamber. It destroys the thermal boundary layer...doctoral thesis 2011

Knobbe, E.M. (author)The aim of this treatise is to present a harmonious mathematical formulation of an explicit moving mesh method that can be used as a basis for many numerical techniques. In most cases a moving mesh is only used to include arbitrary motions and deformations of a geometry into the simulation of a physical problem. The innovative part of this...doctoral thesis 2010

Losurdo, M. (author)In the present dissertation the mathematical modelling of particle deposition is studied and the solution algorithms for particle tracking, deposition and deposit growth are developed. Particle deposition is modelled according to mechanical impact and contact mechanics taking into account the dependency on time, temperature and particle-deposit...doctoral thesis 2009

Paravento, F. (author)In this work the modeling of the interaction of a premixed flame with one ore more obstacles of different shape is considered. The challenge of this work was to design a fast numerical tool suitable for a standard personal computer. A tool able to use a simplified chemical model that removes the need to solve a large system of conservation...doctoral thesis 2009

Beishuizen, N.A. (author)Turbulent spray flames can be found in many applications, such as Diesel engines, rocket engines and power plants. The many practical applications are a motivation to investigate the physical phenomena occurring in turbulent spray flames in detail in order to be able to understand, predict and optimise them. Turbulent spray flames are a two...doctoral thesis 2008
