1. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass
Abstract : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. READ MORE

2. The HCCI Fuel Number - Measuring and Describing Auto-ignition for HCCI Combustion Engines
Abstract : HCCI is an advanced combustion concept, using premixed fuel and air with a diluted charge. This is thermodynamically favorable, leading to high efficiency and therefore lower CO2 emissions. READ MORE

3. Modelling of Multicomponent Fuel Sprays
Abstract : The use of fuel blends (conventional fuels blended with renewable ones) has gained importance in the automotive industry as an option to reduce emissions and dependence on fossil fuels. In order to make the fuel blends commercially viable, computational fluid dynamics (CFD) is used to complement the experiments (done on engines or spray chambers) by providing fundamental insight into spray formation.

4. Spray and Spray Combustion Characteristics of Diesel-Ethanol Fuel Blends
Abstract : In Diesel engines, the quality of fuel atomization and fuel-air mixing inside the cylinder have important effects on the combustion process, and therefore strongly related to the fuel efficiency and emission formation. To understand how the injected fuel mixes with air and combustion processes in a Diesel engine, fundamental spray experiments can be carried out in a constant chamber under different engine-like conditions.

5. 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
