There are many incentives to increase the fuel efficiency of combustion processes. This paper looks at two available options to achieve this goal. The former aims to develop an experimental method that can analyze combustion at extremely high pressures to improve the understanding of high pressure H2/air combustion. Experimental data has been lacking a suitable combustion diagnostic to visualiz...

Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...

A previously healthy 31-year-old man presented to the emergency department complaining of right foot pain and a non-pruritic rash with swelling for one day. He reported spilling jet fuel on his right lower leg at work the previous evening and had worn the fuel-soaked sock for another 10 hours. Physical examination demonstrated a coalescing erythematous macular rash with mild non-pitting edema i...

A 20-year-old male aircraft mechanic presented to our clinic with a chief complaint of hearing loss 1 day after getting sprayed with JP-8 (jet propulsion fuel). The patient reported fuel spraying on his face and ears while taking samples from an aircraft. He reported a persistent burning sensation to his face, lasting approximately 8 hours, followed by a left-sided hearing loss. The patient als...

The near-field of an azimuthally excited round jet was investigated in a combined computational/ experimental study. The reaction zones in the jet were visualized using OH Planar-LaserInduced-Fluorescence ~PLIF! diagnostics. Both axisymmetric and azimuthal modes of the jet were excited to stabilize its spatial structure. Three-dimensional flame visualization of the laboratory jet reconstructed ...

The results of experimental study of plasma-based mixing, ignition and flameholding in a supersonic model combustor are presented in the paper. The model combustor has a length of 600 mm and cross section of 72 mm width and 60 mm height. The fuel is directly injected into supersonic airflow (Mach number M=2, static pressure P(st)=160-250 Torr) through wall orifices. Two series of tests are focu...

Jet propulsion fuel 8 (JP-8) is the major jet fuel used worldwide and has been recognized as a major source of chemical exposure, both inhalation and dermal, for fuel-cell maintenance workers. We investigated the contributions of dermal and inhalation exposure to JP-8 to the total body dose of U.S. Air Force fuel-cell maintenance workers using naphthalene as a surrogate for JP-8 exposure. Derma...

The development of robust desulfurizers and new reforming catalysts is a critical path for the use of jet fuels in powering the commercial growth of fuel cell systems for air and military applications. The presence of high concentrations of sulfur-containing organic compounds leads to rapid deactivation of traditional reforming catalysts, and removal of the sulfur components from the fuel throu...
