Turbulent flame development in a high-pressure combustion vessel [PDF]

open access: yes, 2005
The objective of this work was to extend the range of turbulent burning velocities presented in the literature by performing new measurements at elevated pressures over a range of turbulent velocities, u' (r. m. s. deviation from the mean velocity).
