Effects of fuel/air mixing distances on combustion instabilities in non-premixed combustion

The Physics of Fluids
Combustion instability has been widely reported in several combustion types; however, there is limited information on different fuel/air mixing distances in non-premixed combustion.

Fuel Effect on Combustion Stratification in Partially Premixed Combustion

SAE Technical Paper Series, 2017
<div class="section abstract"><div class="htmlview paragraph">The literature study on PPC in optical engine reveals investigations on OH chemiluminescence and combustion stratification. So far, mostly PRF fuel is studied and it is worthwhile to examine the effect of fuel properties on PPC.

Combustion of Iron Particles Suspension in Laminar Premixed and Diffusion Flames

Combustion Science and Technology, 2020
In the work, the combustion regimes of iron particles (d10 = 4.7 µm) in a laminar pre-mixed flame (LPF) and in an axisymmetric laminar diffusion flame (LDF) are studied.

Premixed combustion in a vortex

Symposium (International) on Combustion, 1989
An asymptotic analysis for large Peclet numbers has been performed in order to describe the roll-up of a premixed flame by a single vortex. In this limit the process consists of two steps: o 1) The fast-time inviscid roll-up of the flame surface as a passive surface into a spiral around the vortex.

Investigation of Effects of Intake Temperature on Low Load Limitations of Methanol Partially Premixed Combustion

Energy & Fuels, 2019
Methanol has unique properties as a fuel, and partially premixed combustion has promising results with high engine efficiency and low emissions. Low load studies with methanol partially premixed combustion are scarce, and the effect of intake temperature

Apparatus for Premixed Combustion Analysis

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">The paper<span class="xref">*</span> describes the design and operation of a laboratory combustion chamber used to study the energy released during the premixed burning phase of diesel combustion. The flow apparatus operates at atmospheric pressure and has the means to provide near quiescent air at ...

Effect of Fuel Injection Pressure and Premixed Ratio on Mineral Diesel-Methanol Fueled Reactivity Controlled Compression Ignition Mode Combustion Engine

Journal of energy resources technology, 2020
Reactivity controlled compression ignition (RCCI) mode combustion has attracted significant attention because of its superior engine performance and significantly lower emissions of oxides of nitrogen (NOx) and particulate matter (PM) compared with ...

PREMIXED AMMONIA-METHANE-AIR COMBUSTION

Combustion Science and Technology, 2005
ABSTRACT The burning velocity and combustion products of premixed ammonia-methane-air flames at room temperature and pressure were measured using an adiabatic flat flame burner, and also simulated using CHEMKIN, for equivalence ratios of approximately 0.5 to 1.5 and for ammonia concentrations of 0% to 5% by volume in the fuel. Concentrations of NO, NO2

Premixed Combustion and Gasdynamics

Annual Review of Fluid Mechanics, 1994
Combustion science is a fascinating field of non equilibrium phenomena in complex systems. Although combustion processes are very diverse in nature, nevertheless, they have two fundamental characteristics: heat release by excess energy of chemical bonds and a strong temperature dependence of the chemical reaction rate.

Characterization of Partially Premixed Combustion

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">Partially Premixed Combustion (PPC) provides the potential of simultaneous reduction of NOx and soot for diesel engines. This work attempts to characterize the operating range and conditions required for PPC. The characterization is based on the evaluation of emission and in-cylinder measurement data of engine ...
