Predicting the Combustion Properties of Hydrocarbon Fuel Mixtures

Chemical Kinetics of Hydrocarbon Ignition in Practical Combustion Systems

Chemical kinetic factors of hydrocarbon oxidation are examined in a variety of ignition problems. Ignition is related to the presence of a dominant chain branching reaction mechanism that can drive a chemical system to completion in a very short period of time. Ignitio n in laboratory environments is studied for problems including shock tubes and rapid compression machines. Modeling of the labo...

DFT studies of hydrocarbon combustion on metal surfaces

Catalytic combustion of hydrocarbons is an important technology to produce energy. Compared to conventional flame combustion, the catalyst enables this process to operate at lower temperatures; hence, reducing the energy required for efficient combustion. The reaction and activation energies of direct combustion of hydrocarbons (CH → C + H) on a series of metal surfaces were investigated using ...

Dynamic Study of Coupled Heavy Hydrocarbon Pyrolysis and Combustion

Hypersonic flight over Mach 5 should be achieved with Supersonic Combustion Ramjet. The regenerative cooling presents the advantage to use the fuel as a coolant, which results in its pyrolysis. Both cooling channel and combustion chamber are studied numerically by coupling the transient phenomena with detailed pyrolysis and combustion chemistry (360 species and 2777 reactions). A Mach 6 flight ...

A Computational Study of the Effects of Combustion Chamber Geometries on Combustion Process and Emission in a DI Diesel Engine

A computational study aiming to investigate the effect of combustion chamber geometry on combustion process and emission has been carried out in a direct injection diesel engine. The combustion process and emission of three different combustion chamber geometries were considered, and combustion process behaviors such as variation of mean pressure, velocity, heat release rate, emission productio...
