Abstract: A method of atomizing a fluid using a pair of counter-rotating rollers including a first roller having grooves, the grooves enclosed by a pair of fins extending away from the first surface and a second roller having channels, the first and second rollers aligned with each other such that the grooves of the first roller mate with the channels of the second roller forming enclosures and nips. The method includes drawing the fluid from a fluid source through the nips, the nips having an upstream side and a downstream side, stretching the fluid between the diverging surfaces of the pair of counter-rotating rollers on the downstream side of the nips to form fluid filaments, and forming fluid droplets from the stretched fluid filaments on the downstream side of the nips between the diverging surfaces of the pair of counter-rotating rollers.

Abstract: An electric motor assisted airblast injector design for gas turbines is disclosed. The electric motor assisted airblast injector assembly consists of an airblast injector, a high speed electric motor and a compressor. The electric motor assisted airblast injector is designed to improve engine light-off and starting reliability without using a fuel staging system to incorporate pressure injectors. A high speed motor is activated during starting to drive a compressor for locally producing pressurized air without sacrificing combustor performance. The pressurized air exiting the air swirler with high velocity penetrates perpendicularly into the fuel spray cone obtained by orifices in the fuel swirler. The amount of pressurized air through the compressor is controlled by motor speed to match fuel starting schedule and produce fuel/air mixture within flammability limits. After engine starting, the high speed motor may cut off as sufficient air pressure differential is available across the combustor.
