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 analysed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations.

Modelling of turbulent lifted jet flames using flamelets: a priori assessment and a posteriori validation [PDF]
, 2014 This study focuses on the modelling of turbulent lifted jet flames using flamelets and presumed PDF approach with interests on both flame lift-off height and flame brush structure.

Anchored and Lifted Diffusion Flames Supported by Symmetric and Asymmetric Edge Flames [PDF]
Symmetry, 2023 Numerous combustion applications are concerned with the stabilization of diffusion flames formed by injecting gaseous fuels into a co-flowing stream containing an oxidizer. The smooth operation of these devices depends on the attachment and lift-off characteristics of the edge flame at the base of the diffusion flame.

Journal of Fluid Science and Technology, 2008 The detailed behaviors of gaseous and spray lifted flames are studied by two- dimensional direct numerical simulations (DNS), and the characteristics of the flamelets are investigated in terms of two key variables for flamelet modeling, namely mixture ...

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 ...

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.

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.

Evaluation of the Flame Lift-off Length in Diesel Spray Combustion Based on Flame Extinction
Journal of Thermal Science and Technology, 2010 The interaction of spray and combustion processes forms a complex system of physical phenomena undergoing in IC engines. Studying this interaction is important to determine strategies for simultaneously reducing soot and NOx emissions from diesel engines.

Double coaxial pipe jet control using DBD-PA and bluff body
Journal of Fluid Science and Technology, 2023 In this study, a double-tube burner nozzle with a DBD-PA (dielectric barrier discharge plasma actuator) and flame holder was employed to regulate the lifted flame.
