Liquid Fuel Composition Effects on Forced, Nonpremixed Ignition

Photo-ignition of Carbon Nanotube for Ignition of Liquid Fuel Spray and Solid Fuel

We have studied the ignition of liquid fuel and certain solid fuels by the photoignition of single wall carbon nanotubes (SWCNTs). Our investigation includes the effect of solid additives such as aluminum nano-particles and solid oxidizers such as ammonium perchlorate (AP) on the photoignition characteristics. We have shown that by mixing CNT with other nanoparticles and powdered material, the ...

Ignition of Liquid Fuel Spray and Simulated Solid

We have studied the ignition of fuel sprays and simulated solid rocket fuels (SRF) by the photoignition of single wall carbon nanotubes (SWCNTs) with an ordinary camera flash. Our investigation includes the effect of solid additives such as aluminum nano-particles and solid oxidizers such as ammonium perchlorate (AP) on the photoignition characteristics. We have shown that by mixing CNT with ot...

Investigating the effects of fuel injection strategies in a dual-fuel diesel-H2 compression ignition engine

In this computational research, the separate and simultaneous impacts of diesel direct injection timing, fuel spraying cone angle, and hydrogen gas addition on combustion characteristics, output emissions, and performance in a single-cylinder direct injection diesel engine was studied. In order to conduct the simulations, valid and reliable models for combustion, break-up, and for turbulence wa...

Fuel Component Effects on Hydrocarbon Emissions from a Spark-ignition Engine

A fuel component perturbation experiment was performed in order to determine the sensitivity of the engine-out emission levels of two olefins, 2-methylpropene (2MP) and 1,3-butadiene, to selected fuel components. In this experiment, a base fuel was perturbed with the following four major fuel components: MTBE, toluene, m,p-xylene, and iso-octane. For each of these components, new fuel mixtures ...
