Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames
Journal of Thermal Science and Technology, 2022 In this study, we have investigated turbulent premixed flames affected by local stretch in a swirl flow, measured by the simultaneous OH-PLIF/SPIV system. Evaluating the transient of burning velocity and stretch rate, the flow and the flame dynamics in a

Measurement of turbulent flame speed of natural gas/air mixtures at elevated pressure [PDF]
, 2010 Turbulent flame speeds were measured over a range of pressures to 0.8 MPa using a jet flow apparatus fired with a synthetic mixture representing a mid-European natural gas. The equivalence ratio empty set was 0.9.
