LES of Partially Premixed Combustion

2002
Numerical studies devoted to partially premixed combustion are first reviewed. Then a Large Eddy Simulation procedure is proposed for these flames when they develop in turbulent flows. The corresponding subgrid combustion modeling is tested for the case of a turbulent lifted-flame.

Incomplete combustion in nonadiabatic premixed gas flames

Physical Review E, 1996
The inward propagating spherical flame and burner stabilized Bunsen-type flame of low-Lewis-number premixtures are studied numerically. It is shown that reduction of the reaction rate induced by the flame stretch makes the flame vulnerable to the radiative heat losses which may well result in a partial or complete extinction of the flame.

Effects of fuel injection parameters on premixed charge compression ignition combustion and emission characteristics in a medium-duty compression ignition diesel engine

International Journal of Engine Research, 2019
From the different power plants, the compression ignition diesel engines are considered the best alternative to be used in the transport sector due to its high efficiency.

Combustion Noise from Non-premixed and Lean-premixed Swirl Flames

Acta Acustica united with Acustica, 2009
The development of modern gas turbines and jet engines is focused on the reduction of pollutant emissions and, increasingly, on the reduction of overall noise emission, including combustion noise. This requires the minimization of the noise sources, namely noise from the turbulent flow, combustion noise and noise caused by periodic instabilities and ...

Combustion Modeling of Diesel Combustion with Partially Premixed Conditions

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">Two turbulent combustion modeling approaches, which were large eddy simulations in conjunction with detailed kinetics (LES-CHEMKIN) and Reynolds Averaged Navier Stokes with detailed kinetics (RANS-CHEMKIN), were used to model two partially premixed engine conditions.

Modeling partially premixed turbulent combustion

2001
This paper investigates the process of partially premixed turbulent combustion in situations where the fuel is provided either as a liquid spray or a purely gaseous stream. In the former case, two-dimensional direct numerical simulations in association with a Lagrangian solver for the dispersed vaporizing phase are employed.

Combustion of partially premixed spray jets

Proceedings of the Combustion Institute, 2005
Abstract Gas turbines, liquid rocket motors, and oil-fired furnaces utilize the spray combustion of continuously injected liquid fuels. In most cases, the liquid spray is mixed with an oxidizer prior to combustion, and further oxidizer is supplied from the outside of the spray to complete diffusion combustion.

Active control of combustion oscillations for premixed combustion systems

Journal de Physique IV (Proceedings), 2002
Methane premixed flame is studied extensively using a swirl burner and a swirl combustion chamber. First the fundamental study for the flame properties is performed for the swirl burner. Flame configuration is analyzed by a high speed photography and Schlieren system. Then a control system is set up using MATLAB, Simulink, PPC Controller board, dSPACE,
