Turbulent burning velocity measurements: Extended to extreme levels of turbulence [PDF]
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.

The turbulent burning velocity of iso-octane/air mixtures [PDF]
Turbulent burning velocities of iso-octane air mixtures have been measured for expanding flame kernels within a turbulent combustion bomb. High speed schlieren images were used to derive turbulent burning velocity. Turbulent velocity measurements were made at u’ = 0.5, 1.0, 2.0, 4.0, 6.0 m/s, equivalence ratios of 0.8, 1.0, 1.2, 1.4 and pressures of P =

Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames
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
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.

Transient combustion responses of homogeneous propellants to acoustic oscillations in axisymmetric rocket motors [PDF]
A numerical analysis of unsteady motions in solid rocket motors has been conducted. The formulation considers a 2-D axisymmetric combustion chamber and a choke nozzle, and treats the complete conservation equations accounting for turbulence closure ...

Fluid-mechanical structure of methane-air and propane-air turbulent premixed flames
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.

The Thermonuclear Explosion Of Chandrasekhar Mass White Dwarfs [PDF]
The flame born in the deep interior of a white dwarf that becomes a Type Ia supernova is subject to several instabilities. We briefly review these instabilities and the corresponding flame acceleration. We discuss the conditions necessary for each of the
