Droplet size from Venturi air induction spray nozzles

چکیده

Abstract Sprays are of great importance for many applications, with drop size being a crucial parameter. Especially in agriculture simple flat fan spray nozzles often supplemented by Venturi component to achieve larger sizes and hence, prevent unwanted drift the smallest droplets. The general believe is that these drops usually attributed fact liquid sheet produced nozzle breaks up more easily due pre-existing ’holes’ formed induced air bubbles. Here, we extend descriptions how fluid parameters determine droplet distributions from nozzles. We show mean determined nozzle’s orifice area as case ordinary nozzles, but additional pressure over chamber needs be taken into account. Using this parameter, relations were derived can re-used. This allows increase compared conventional chamber, not change breakup mechanism presence bubbles sheet.

Measuring Spray Droplet Size from Agricultural Nozzles Using Laser Diffraction

When making an application of any crop protection material such as an herbicide or pesticide, the applicator uses a variety of skills and information to make an application so that the material reaches the target site (i.e., plant). Information critical in this process is the droplet size that a particular spray nozzle, spray pressure, and spray solution combination generates, as droplet size g...

Venturi easy ambient sonic-spray ionization.

The development and illustrative applications of an ambient ionization technique termed Venturi easy ambient sonic-spray ionization (V-EASI) is described. Its dual mode of operation with Venturi self-pumping makes V-EASI applicable to the direct mass spectrometric analysis of both liquid (V(L)-EASI) and solid (V(S)-EASI) samples. V-EASI is simple and easy to assemble, operating solely via the a...
