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

Turbulent burning velocity in combustion chamber of SI engine fueled with compressed biogas
Vietnam Journal of Mechanics, 2015 Turbulent burning velocity is the most important parameter in analyzing pre-mixed combustion simulation of spark ignition engines. It depends on the laminar burning velocity and turbulence intensity in the combustion chamber.

Fluid-mechanical structure of methane-air and propane-air turbulent premixed flames
Nihon Kikai Gakkai ronbunshu, 2015 The flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic of turbulence have been closely examined by using a three-color six-beam LDV system.

Journal of Engineering and Sustainable Development, 2020 The achievement of precise measurements on the laminar diffusion flames plays a big role in the process of realizing a wide flames range. Despite most of fuel is likely burnt in the turbulent combustion, there is still data requirement for the data on ...

Turbulent burning velocity measurements: Extended to extreme levels of turbulence [PDF]
Proceedings of the Combustion Institute, 2017 Abstract Previous measurements of turbulent burning velocity ( S T ) have been reported by Gulder and colleagues for intense levels of turbulence, defined to be u ’⁄ S L values between 12 and 24, and normalized integral scales ( L x ⁄ δ L ) up to 46.

On defining the turbulent burning velocity in premixed V-shaped turbulent flames [PDF]
Combustion and Flame, 1984 Abstract Turbulent buring velocity S t is determined for six premixed V-shaped turbulent flames. In addition to defining S t with respect to the conventional flame surface, a definition based on an effective flame orientation is proposed. The results based on the flame surface increase significantly with distance from the flame stabilizer ...

Journal of Thermal Science and Technology, 2006 The laminar burning velocity of pre-mixed hydrogen-air mixtures was measured in a fan stirred combustion bomb. Unstretched laminar burning velocities and Markstein lengths were obtained at 0.10MPa for equivalence ratios of 0.4, 0.6, 0.8 and 1.0 using ...
