Gas sampling method for determining pollutant concentrations in the flame zone of two swirl-can combustor modules [PDF]
A gas sampling probe and traversing mechanism were developed to obtain detailed measurements of gaseous pollutant concentrations in the primary and mixing regions of combustors in order to better understand how pollutants are formed.

Performance and durability of improved air-atomizing splash-cone fuel nozzles [PDF]
An improved design of air-atomizing fuel nozzles was determined from a study of four differently shaped splash-cone fuel nozzles after 56 hr of durability testing in a combustor segment.

NASA/Pratt and Whitney experimental clean combustor program: Engine test results [PDF]
, 1977 A two-stage vorbix (vortex burning and mixing) combustor and associated fuel system components were successfully tested in an experimental JT9D engine at steady-state and transient operating conditions, using ASTM Jet-A fuel. Full-scale JT9D experimental

Mechanism of methanol and formaldehyde emissions from methanol-fueled engines
Fuel Processing TechnologyMethanol, as a low-carbon fuel, has broad application prospects in engines. The mechanism of methanol and formaldehyde was investigated respectively in a methanol premixed combustion test bench (PCTB) and a 304 stainless-steel flow reactor (SFR).

Ignition of Deflagration and Detonation Ahead of the Flame due to Radiative Preheating of Suspended Micro Particles [PDF]
, 2015 We study a flame propagating in the gaseous combustible mixture with suspended inert particles. The gas is assumed to be transparent for the radiation emitted by the combustion products, while particles absorb and re-emit the radiation. Thermal radiation

Case Studies in Thermal EngineeringOur previous study demonstrated that divergent micro-nozzles designed for H2-fueled domestic gas stoves can achieve a higher flame temperature than conventional straight micro-nozzles, but are more susceptible to flashback. To address this safety concern,
