Spray Angle and Atomization in Diesel Sprays
SAE Technical Paper Series, 1984<div class="htmlview paragraph">In this investigation, cone angles of high pressure diesel sprays emerging through plain orifices were studied. The study was conducted at constant fuel pressures by using injection system in a single pulse mode.

Effects of spray height and spray angle on spray deposition in tobacco plants
2011 6th IEEE Conference on Industrial Electronics and Applications, 2011Due to the decreasing availability of authorized plant protection products, adequate pest control becomes more difficult in tobacco. Although much attention is given to predator-pest interactions in integrated control, almost no research is available about the optimization of spray application techniques in tobacco plants.

Effect of Spray Angle on Deposition Characteristics in Cold Spraying
International Thermal Spray Conference, 2003Abstract A typical feature of cold spray process is that a deposit can be formed without change of the original structure and compositions of spray materials. Only particles which reach the velocity higher than the critical velocity can be deposited on a substrate in cold spraying.

Transient Spray Cone Angles in Pressure-Swirl Injector Sprays
SAE Technical Paper Series, 2004<div class="htmlview paragraph">The transient cone angle of pressure swirl sprays from injectors intended for use in gasoline direct injection engines was measured from 2D Mie scattering images. A variety of injectors with varying nominal cone angle and flow rate were investigated.

Effect of Spray Angle in Spray Cooling Thermal Management of Electronics
Volume 4, 2004The paper presents an experimental and numerical study of the effect of spray angle on spray cooling when applied in the thermal management of electronics. A thermal test chip provided the heated target, and was cooled by a single pressure swirl atomizer. A perfluorocarbon (PF5060) was employed as the coolant. The coolant was subcooled to a fixed level

The Influence of Spraying Angle on Properties of HVOF Sprayed Hardmetal Coatings
Journal of Thermal Spray Technology, 2010The spraying angle is one of the deposition parameters that influence the quality of thermally sprayed coatings. In theory, decreasing the spraying angle results in lower process deposition efficiency, whereas the porosity of coatings increases, becoming a cause of poorer microstructure and mechanical properties.

Measurements of the Spray Angle of Atomizing Jets
Journal of Fluids Engineering, 1983Liquid jets are considered issuing from single-hole, round nozzles into quiescent gases under conditions such that they break up into a well defined conical spray immediately at the nozzle exit plane. The initial angles of such sprays were measured at room temperature by a spark photography technique.

Effects of nozzle type and spray angle on spray deposition in ivy pot plants
Pest Management Science, 2010AbstractBACKGROUND: Fewer plant protection products are now authorised for use in ornamental growings. Frequent spraying with the same product or a suboptimal technique can lead to resistance in pests and diseases. Better application techniques could improve the sustainable use of the plant protection products still available.

Study on the characteristic of the spray angle in pressure swirl spray atomisation
Applied Mathematics and Mechanics, 1987Based on the suggested atomisation theory for the swirl spray conical film, the formula for the spray angle characteristic of pressure swirl spray atomisation,θ=tg−12·(1−Φ) is derived from the relation of acting forces in swirl spray.
