Spray Characterization of Gasoline Direct Injection Sprays Under Fuel Injection Pressures up to 150 MPa with Different Nozzle Geometries

SAE technical paper series, 2019
Maximum fuel injection pressures for GDI engines is expected to increase due to positive effects on emissions and engine-efficiency. Current GDI injectors have maximum operating pressures of 35 MPa, but higher injection pressures have yielded promising ...

Nozzle Spraying Model of Combustion Thermal Spray

Advanced Materials Research, 2013
The flame used in combustion flame spraying is typical of a high-temperature free jet. The flow fields of free jets are multi-phase flows that couple the mass and heat transfer. The analytical and numerical solutions to turbulent flows are engineering approximations. This work uses Prandtle’s mixing-length theory to describe the flame spreading of free

New Atomization Nozzle for Spray Drying

Drying Technology, 2013
A new atomization nozzle based on ink jet technology is introduced for spray drying. Application areas are the food and dairy industry, in the first instance, because in these industries the quality demands on the final powders are high with respect to heat load, powder shape, and size distribution.

Plain Orifice Spray Nozzles

2010
Plain orifice, or “pressure atomizers” are the most commonly used atomizers due primarily to their simplicity and ease of manufacture. This chapter provides background on the characteristics of these devices in terms of spray production and general behavior.
