Outline of Final Research Achievements

Practical combustors are operated in conditions of high Reynolds numbers and high pressure, and turbulent flame structures generated by hierarchical structure of turbulent flows dominate characteristics of turbulent combustion. In this research project, structures of turbulent premixed flames in high pressure and high Reynolds number conditions are investigated by DNS with parallel GPU cloud and by multi-dimensional combined laser diagnostics. Based on the characteristics of turbulent flame structures, an SGS combustion model has been developed and LES of turbulent combustion has also been established.
