Ignition Characteristics Of Turbulent Jet Flows [PDF]
Chemical Engineering Research and Design, 2002 Releases of flammable materials from chemical plant are a hazard since their dispersion down to safe levels only occurs at some distance from their source. Within this distance, accidental ignition can give rise to fires or explosions. This paper describes the development of computational fluid dynamic models capable of predicting the ignition hazards ...

The impact of gasoline formulation on turbulent jet ignition
Fuel, 2022 Turbulent jet ignition (TJI) is a promising technology for burning ultra-lean mixtures; the process is comprised of hot reactive jets issuing from a pre-chamber (PC) and initiating combustion in the main chamber (MC). The present study employs a simplified zero-dimensional (0D) partially stirred reactor (PaSR) model to describe the complex mixing and ...

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

Anchoring of premixed jet flames in vitiated crossflow with pulsed nanosecond spark discharge
Applications in Energy and Combustion Science, 2020 This paper deals with the effect of non-equilibrium plasma on the anchoring of a premixed jet flame in hot vitiated crossflow at atmospheric pressure. The turbulent vitiated crossflow was generated by an array of 4×4 premixed turbulent jet flames burning
