Amide and Ester-Functionalized Humic Acid for Fuel Combustion Enhancement
… with kerosene to identify the influence on combustion properties. Butyl-modified humic acid samples decreased the molar enthalpy of combustion. Hexyl, octyl, and decyl-modified humic acids improved the combustion values. Decyl amide-modified humic acid showed the largest improvement of these …

Investigation of combustion enhancement with biomass derived fuels blended with diesel
… no net increase of CO2 emissions from bio-fuel combustion; the plants, from which biofuels are derived, absorb CO2 from the atmosphere. As there is now bio-ethanol in gasoline, the analogous additive to diesel would be bio-butanol, another alcohol. The intermediate product in the bio-butanol …

An Investigation of Controlled Oscillations in a Plasma Torch for Combustion Enhancement
… shock and resulting control of the supersonic combustion process. This research will capitalize on previous results [Gallimore, 1998] which indicate that the plasma torch oscillations originate from the inherent oscillations of the voltage applied to the torch. The aim of this research is to …

Performance of a Plasma Torch with Hydrocarbon Feedstocks for Use in Scramjet Combustion
… of the plasma torch as an igniter in high-speed combustion environments was investigated through the use of emission spectroscopy and a NASA chemical kinetics code. All feedstocks tested; argon, methane, ethylene and propylene, were able to start. The voltage data indicated that there were two …

Operation Characteristics of a Plasma Torch for Supersonic Combustion Applications with Simulated Cracked JP-7 Feedstock
… combined with an aeroramp to assist with the combustion process. The present investigation tested the plasma torch with a feedstock mixture of gaseous hydrocarbons that simulates thermally cracked JP-7 jet fuel. This simulation of a cracked hydrocarbon fuel was studied to lay the foundation …

Investigation of Ozone Initiated Ethylene Oxidation at Room Temperature: Chemistry and Flame Dynamics
… has been proved to be efficient and effective in combustion enhancement and control. For saturated fuels, it is recognized that the O3 decomposition at elevated temperatures dominantly contributes to the improvement. However, for unsaturated fuels, the knowledge is limited, due to the much more …

Using optical techniques to measure aluminum burning in post-detonation explosive fireballs
… in the explosive fireball. Efforts in aluminum combustion have focused on aluminum monoxide (AlO) emission because it is easy to measure, and it is a combustion marker in some cases; however, the first part of the current study has indicated that explosive fireballs are optically thick. …
