Ignition Phenomenon of Inhomogeneously-distributed Fuel Spray.

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...

Investigation of the Ignition and Combustion Processes of a Dual Fuel Spray under Diesel-like Conditions using CFD Modeling

Recent research activities in the field of Diesel engines have shown the potential to reduce pollutant emissions and improve thermal efficiency by controlling fuel reactivity. However, understanding the impact of blending fuels with different physical and especially chemical properties on diesel-like spray mixing and combustion processes is still a challenge. Since the experimental techniques a...

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...
