Modeling and research of combustion processes of tangentially swirled air-fuel mixture

AIP Conference Proceedings, 2021
The search and development of alternative energy sources for human life is a priority task for modern society. One of the promising directions is the use of biogas as a source of thermal energy for power plants. It is established that the main difference between biogas and natural gas is caused by the presence of more than 30% of carbon dioxide in its ...

Hot-body ignition limits for air-fuel mixtures

Combustion, Explosion and Shock Waves, 1965
1. The hot-body ignition temperatures under free convection conditions and the dependence of TS on composition were measured for air mxtures of hydrogen, acetylene, carbon disulfide, ethylene glycol ethyl ether, and diethyl ether. 2. It was established that ignition can occur at TS to 180°C which is incompatible with a thermal mechanism.

Transient plasma ignition of quiescent and flowing air/fuel mixtures

IEEE Transactions on Plasma Science, 2005
Transient plasmas that exist during the formative phase of a pulse-ignited atmospheric pressure discharge were studied for application to ignition of quiescent and flowing fuel-air mixtures. Quiescent methane-air mixture ignition was studied as a function of equivalence ratio, and flowing ethane-air mixture was studied in a pulse detonation engine (PDE)

Laser ignition in flowing air-fuel mixture

Laser Ignition Conference 2017, 2017
Influence of the flow of air-fuel mixture on laser ignition in a high-pressure environment was studied. It was found that the lean ignition limit of laser ignition was reduced by the flow.

Investigation of the Flame Stabilization Mechanism in Phase-Inhomogeneous Air—Fuel Mixtures

Russian Aeronautics, 2020
The mechanism of flame stabilization in phase-inhomogeneous air—fuel mixtures is considered. A method is proposed for refining the thermal theory of flame stabilization by taking into account the heat consumed for heating and evaporation liquid fuel in the ignition zone.

Computational Study of the Air/Fuel Mixture in a Small Spark Ignition Engine

Volume 2: 27th Computers and Information in Engineering Conference, Parts A and B, 2007
In an effort to understand the fluid dynamics in the droplet formation process, during the fuel delivery portion of operation of a small spark ignition engine, a computational study of the process was undertaken. A combination of high-speed photography and Computational Fluid Dynamics was used to investigate the droplet formation process.

Kinetics of NO Formation and Decay in Nanosecond Pulse Discharges in Air-Fuel Mixtures

53rd AIAA Aerospace Sciences Meeting, 2015
Time-resolved, absolute NO and N atom number densities are measured by NO Laser Induced Fluorescence (LIF) and N Two-photon Absorption LIF in a diffuse plasma filament, nanosecond pulse discharge in dry air, hydrogen-air, and ethylene-air mixtures at 40 Torr, over a wide range of equivalence ratios.

A Study of Air-Fuel Mixture Formation in Direct-Injection SI Engines

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">An investigation was made into two approaches to air-fuel mixture formation in direct injection SI engines in which charge stratification is controlled by swirl or tumble gas motions, respectively. Particle image velocimetry (PIV), laser-induced fluorescence (LIF) and air-fuel ratio measurement by infrared ...

Study of Air-Fuel Mixture Preparation in a Single Cylinder SI Engine

SAE Technical Paper Series, 2010
<div class="section abstract"><div class="htmlview paragraph">Engine operation at low temperatures is of considerable interest from the standpoint of exhaust gas emissions and fuel economy. A semi-empirical film model is developed to study the transient cold starting process.

Transient Plasma Ignition of Quiescent and Flowing Air/Fuel Mixtures

2022
Transient plasmas that exist during the formative phase of a pulse-ignited atmospheric pressure discharge were studied for application to ignition of quiescent and flowing fuel-air mixtures. Quiescent methane–air mixture ignition was studied as a function of equivalence ratio, and flowing ethane–air mixture was studied in a pulse detonation engine (PDE)
