Simulation of turbulent flames relevant to spark-ignition engines
… for internal combustion (IC) engines. Therefore, models used to predict such combustion have to be 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 …

Flamelet modelling of soot formation in diffusion flames
In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar …

Analyses of Bluff Body and Swirl-Stabilised Flames Using Large Eddy Simulation
… interactions require modelling. Statistical flamelet models are a subgroup of combustion models that are computationally inexpensive, but have proven to be robust in capturing the flame stabilisation mechanisms. In this work, a presumed joint Probability Density Function (PDF) with laminar …

Large eddy simulation of premixed combustion using flamelets
… eddies down to a cut-off scale are solved, with models to mimic the influences of sub-grid scales. Since the flame front is thinner than the smallest scale resolved in a typical LES, the premixed combustion is a sub-grid scale (SGS) phenomenon and involves strong interplay among small-scale …
