1. Kinetic modeling of autothermal reforming of heptane for a fuel cell - auxiliary power unit
Abstract : AbstractThe transport sector contributes significantly to the increasing amounts of air pollution. The pollution from idling heavy duty vehicles can be reduced by using a fuel cell auxiliary power unit (FC-APU) that supplies the vehicle with electricity. This licentiate thesis deals with production of hydrogen, which feeds the fuel cell. READ MORE

2. Combustion Chemistry Investigation of Liquid and Solid Fuels
Abstract : The aim of this work was to study the combustion of liquid and solid fuels with the emphasis on intermediates and products. Depending on the structure and the complexity of the fuel different reactors and methods were used. Small-scale laboratory reactors were built and chemical analysis and evaluation methods were developed. Heptane. READ MORE

3. A Detailed Modeling Study for Primary Reference Fuels and Fuel Mixtures and Their Use in Engineering Applications
Abstract : The aim of this work is to generate detailed and simplified kinetic models for the oxidation of the Primary Reference Fuels (PRF) n-heptane, iso-octane and their mixtures, with low numbers of species and reactions. These mechanisms are consistent in terms of the choice of kinetic parameters for the different reaction classes. READ MORE

4. Identification of principal chemical subsets of biofuel combustion : Ants walking in renewable fire
Abstract : The work in this thesis was carried out to highlight important chemical pathways in skeletal mechanisms for the three smallest alcohol fuels (methanol, ethanol and npropanol), two representative fuel alkanes n-heptane and n-decane, and finally the biodiesel surrogates, methyl-decanoate, methyl-5-decenoate, and methyl-9-decenoate. This aim was set up to further the efforts of creating Computational Fluid Dynamics (CFD) suitable mechanisms, which in turn can be used by the industry to improve, for example, engines or gas turbines, or by academia to further understand turbulent combustion.

5. Homogeneous Ignition - Chemical Kinetic Studies for IC-Engine Applications
Abstract : Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. READ MORE
