INVESTIGATION OF FLAME STRETCH IN TURBULENT LIFTED JET FLAME [PDF]
Combustion Science and Technology, 2014 DNS data of a laboratory-scale turbulent lifted hydrogen jet flame has been analyzed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations. The mixed mode combustion is observed in instantaneous structures as in earlier studies and in averaged structure, in which the predominant mode is found to ...

Numerical analysis of lifted hydrogen flame [PDF]
MATEC Web of Conferences, 2018 A numerical analysis of a turbulent lifted H2/N2 flame is presented. As combustion mechanisms, a large spectrum is considered including single-step and two-step, as well as detailed mechanisms.

Lifted flame property and interchangeability of natural gas on partially premixed gas burners
Case Studies in Thermal Engineering, 2018 The relationship between lifted flames and burner head temperature of partially premixed gas burners supplied by various natural gas sources was investigated, and the application of AGA(American Gas Association) lifting limit for Chinese domestic gas ...

A numerical study of a lifted $$\hbox {H}_2/\hbox {N}_2$$ H 2 / N 2 flame excited by an axial and flapping forcing [PDF]
Scientific Reports, 2022 The large eddy simulation method combined with the Eulerian stochastic field approach has been used to study excited lifted hydrogen flames in a stream of hot co-flow in a configuration closely corresponding to the so-called Cabra flame.

Soot control of laminar jet-diffusion lifted flame excited by high-frequency acoustic oscillation
Journal of Thermal Science and Technology, 2017 A novel technology to reduce soot is developed utilizing a high-frequency standing wave of 20 kHz applied to a methane-air lifted jet flame base. The amount of soot was measured using the transmitted light attenuation method. A mixing profile of the fuel

LIFTED LAMINAR JET DIFFUSION FLAMES [PDF]
Combustion Science and Technology, 2005 This paper addresses the numerical description of lifted flames in axisymmetric laminar coflow jets. The analysis considers moderately large values of the Reynolds number, when the boundary-layer approximation can be used to describe the slender mixing region that extends between the jet exit and the flame, providing the profiles of velocity and ...
