Experimental Characterisation of Swirl Stabilized Annular Stratified Flames [PDF]

, 2007
A burner for investigating lean stratified premixed flames propagating in intense isotropic turbulence has been developed. Lean pre-mixtures of methane at different equivalence ratios are divided between two concentric co-flows to obtain annular ...

Laser-induced incandescence in turbulent non-premixed flames at elevated pressure

, 2017
There is general interest in understanding sooting behavior in canonical flames at elevated pressures. In this study, a new apparatus is used to evaluate sooting turbulent non-premixed flames at 1 atm and 3 atm, with constant Reynolds number.

Mathematical modelling of premixed laminar methane-air flames [PDF]

, 1994
Two mathematical models have been developed to simulate two-dimensional, premixed, laminar, stationary, axisymmetric methane-air flames, and successfully validated with non-intrusive Coherent Anti-Stokes Raman Spectroscopy (CARS) temperature ...

Large-eddy simulation of kerosene spray combustion in a model scramjet chamber

, 2010
Large-eddy simulation (LES) of kerosene spray combustion in a model supersonic combustor with cavity flame holder is carried out. Kerosene is injected through the ceiling of the cavity.

Response mechanism of methane non-premixed diffusion flame under the influence of an applied magnetic field

Case Studies in Thermal Engineering
To explore the influence of an applied magnetic field on non-premixed diffusion flames, a methane non-premixed diffusion flame combustion system was constructed.

High-Performance Computing Optimization of the Maxwell–Stefan Diffusion Model in OpenFOAM

Applied Sciences
Multicomponent diffusion modeling based on the Maxwell–Stefan formulation is widely used in high-fidelity combustion simulations due to its superior physical accuracy compared with simplified diffusion models. However, the computational complexity of the

Experimental study of combustion and scalar mixing in swirling jet flows

Turbulent mixing of passive scalar field and combustion of gaseous fuel were studied in the context of a non-premixed isothermal and reacting swirling jets discharged from a swirl-stabilised burner, as a function of swirl number.

Lift-off of non-premixed turbulent CH4 jet flames at elevated pressures

, 2017
In this study, the lift-off behavior of non-premixed turbulent jet flames (120 kPa to 500 kPa) is explored at elevated pressures, extending the current knowledge limited to sub-atmospheric and atmospheric pressure conditions. Experiments are conducted in

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor

Applications in Energy and Combustion Science
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...
