Investigation of Smoke Emission Factors and Combustion Improvement Using Multi-hole Diffusion Nozzle (Staggered Nozzle)

Numerical Investigation in the Effect of Number of Nozzle Hole on Performance and Emission in Dual Fuel Engine

Air pollution is one of the major issues about the diesel engines in todays' world. It is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. Natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilot ...

Investigation of Carbon Nanotube Growth Using a Nozzle CVD Method

Numerical Investigation of Supersonic Nozzle Flow Separation

S EPARATION of supersonic flow in a convergent–divergent nozzle is a fundamental fluid phenomenon that affects a large variety of applications, from fuel systems to aircraft engine nozzles. When a supersonic nozzle is operated at pressure ratioswell below its design point, a shock forms inside the nozzle andflowdownstreamof the shock separates from the nozzle walls. Even though flow separation ...

Investigation of Hypersonic Nozzle Flow Uniformity Using NO Fluorescence

Planar laser-induced fluorescence visualisation isused to investigate nonuniformities in the flow of a hyper-sonic conical nozzle. Possible causes for the nonuniformityare outlined and investigated, and the problem is shown to bedue to a small step at the nozzle throat. Entrainment of coldboundary layer gas is postulated as the cause of the signalnonuniformity.
