Modelling spherical flame propagation in a closed volume
… behaviour of alternative fuels. The laminar flame speed of a combustible mixture is a well defined combustion characteristic that influences the efficiency and performance of many combustion processes. An example of where flame speed has a strong impact on the performance of a combustion …

Measurement of flame propagation through step changes in mixture composition
Flame speed is a central metric in the field of combustion. While particular mixtures have characteristic flame speeds, it has also been shown that in compositionally stratified mixtures, flames exhibit a path dependency, or memory effect. The goal of the experimental work presented in this thesis …

Laser shadowgraph study of early flame propagation in swirling flows near the lean misfire limit.
… locations on the specific rate of growth of flame area, the flame speed and the convection velocity are investigated experimentally in a constant volume vessel near the lean misfire limit for an equivalence ratio of 0.645 using the shadowgraph technique. The circular and the elliptical models …

Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation
The laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. The laminar burning velocity of rich and lean hydrogen flames was studied …

Simulation of turbulent flames relevant to spark-ignition engines
… reliable, accurate and robust. In this work, the flamelet approach in the Reynolds-Averaged Navier- Stokes framework, is used to simulate flames relevant to spark-ignition IC engines. A central quantity in the current modelling approach is the scalar dissipation rate, which represents coupling …
