چکیده
ABSTRACT The correct deposition of spray along the canopy is important for phytosanitary control in coffee plants; however, structure plant makes this distribution difficult. This study aimed to evaluate a tracer on leaves and fruits cultivation, with respect application rate type hydraulic nozzle, as well use an electrostatic spraying system. A hydropneumatic sprayer was used, nozzles empty conical jet series TVI (coarse droplets air induction) or JA (fine droplets), at rates 200 400 L ha-1. An system, SPE-2 nozzle ha-1, also evaluated. upper, middle lower thirds trees, losses ground projection, were quantified using spectrophotometry. results indicated that provides greater upper third than application, regardless rate. loss nozzle. Although ha-1 it causes ground.

Statistical Modeling for Oblique Collision of Nano and Micro Droplets in Plasma Spray Processes
Spreading and coating of nano and micro droplets on solid surfaces is important in a wide variety of applications including plasma spray coating, ink jet printing, DNA synthesis and etc. In spraying processes, most of droplets collide obliquely to the surface. The purpose of this article is to study the distribution of nano and micro droplets spreading when droplets impact at an oblique a...
متن کاملModeling Spray Pyrolysis Deposition
The deposition of a thin tin oxide film allows for the manufacture of modern gas sensors. Spray pyrolysis deposition is used to grow the required thin films, as it can be seamlessly integrated into a standard CMOS processing sequence. A model for spray pyrolysis deposition is developed and implemented within the Level Set framework. Two models for the topography modification due to spray pyroly...
متن کاملGlobal Rainbow Thermometry for Average Temperature Measurement of Spray Droplets
Global Rainbow Thermometry is presented. It is a new technique for measuring average size and temperature of spray droplets. For data inversion, a global rainbow pattern is employed, which is formed by constructive interference of laser-light scattering spherical droplets. The non-spherical droplets and liquid ligaments provide a uniform background and thus do not influence the interference pat...
