Hydrothermal ethanol flames in Co-flow jets [PDF]
The Journal of Supercritical Fluids, 2019 Results on the autoignition and stabilization of ethanol hydrothermal fames in a Supercritical Water Oxidation (SCWO) reactor operating at constant pressure are reported. The flames are observed as luminous reaction zones occurring in supercritical water; i.e., water at conditions above its critical point (approximately 22 MPa and 374 °C).

Stability and Liftoff of a N2-in-H2 Jet Flame in a Vitiated Co-flow at Atmospheric Pressure
Eurasian Chemico-Technological Journal, 2014 The stability and liftoff characteristics of a nitrogen (N2) diluted hydrogen (H2) jet flame in a vitiated co-flow are investigated experimentally with particular attention focused on regimes where multiple stabilization mechanisms are active ...

Flame Stabilisation Mechanism for Under-Expanded Hydrogen Jets
FireA hydrogen under-expanded jet released from a high-pressure vessel or equipment into the atmosphere through a 0.53 mm diameter orifice results in a sustained lifted flame for pressures above 4 MPa and flame blow-out at pressures below 3 MPa. Knowledge of

Model constant C of turbulent NO reaction time model
Case Studies in Thermal Engineering, 2017 The NO concentration of turbulent jet flames with different fuel, jet velocity, and jet diameter are simulated with the turbulent NO reaction time model. The predicted NO profile has very good agreement with the experimental data.

Burned Gas Characteristics of Laminar Lifted Flame at the Beginning of Stream Heating
Journal of Thermal Science and Technology, 2011 This research experimentally investigates the exhaust gas characteristics of a methane-air lifted-jet flame with elevated stream temperatures up to 450 K. Emission indices of NOx and CO were measured by direct gas sampling using a gas detector tube.

Simulation of hydrogen auto-ignition in a turbulent co-flow of heated air with LES and CMC approach [PDF]
, 2011 Large-Eddy Simulations (LES) with the first order Conditional Moment Closure (CMC) approach of a nitrogen-diluted hydrogen jet, igniting in a turbulent co-flowing hot air stream, are discussed. A detailed mechanism (nine species, 19 reactions) is used to
