Effects of spray height and spray angle on spray deposition in tobacco plants

2011 6th IEEE Conference on Industrial Electronics and Applications, 2011
Due 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, 2003
Abstract 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, 2004
The 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

Spray coating of superhydrophobic and angle-independent coloured films

Chemical Communications, 2014
Angle-independent coloured films with superhydrophobicity were fabricated from quasi-amorphous arrays of monodispersed fluorinated silica nanoparticles via one-step spray coating. The film exhibited a high contact angle (>150°) and a low roll-off angle (~2°) and the colour could be tuned to blue, green and moccasin by varying the size of the ...

Influence of Spray Angle on Cold Spray with Al for the Repair of Aircraft Components

International Thermal Spray Conference, 2014
Abstract This study deals with the influence of spray angle on the deposition of cold-sprayed Al particles. Spray trails were conducted in parallel with finite element simulations of particle deformation and coating build-up as a function of spray angle, powder size, substrate roughness, and surface configuration.

The Influence of Spraying Angle on Robotic Trajectory Planning

Applied Mechanics and Materials, 2013
The influence of roll angle on coating uniformity is analyzed by establishing the formula between the average film thickness and it. The functional relations of coating uniformity to yaw angle and roll angle are obtained by measuring the average film thickness under the diferrent angles. The minor changes of spray angle have little influence on coating

Splat Formation in Off-Normal Angle Spray

International Thermal Spray Conference, 2000
Abstract This article examines the splat shape at off-normal angles in plasma spray and investigates the relationship between the splat elongation ratio and the spray angle on various spray materials and particle sizes. The applicability of the model to the experimental results is investigated.

Increasing efficacy of graminicides with a forward angled spray

Crop Protection, 2012
Abstract Control of annual grass species with vertically oriented leaves in agricultural crops by application of foliar acting herbicides with conventional hydraulic sprayers can be increased using forward angled nozzles. Changing the spray angle from the normally predominantly vertical spray towards an angled spray increases the potential target ...
