The aerial atomizer is the most essential component of plant protection UAV (unmanned vehicle). However, structural optimization existing atomizers lacks comprehensive consideration spray parameters and parameters, there a shortage available models, resulting in unstable effect application. In our previous work, an dual-atomization centrifugal was developed. order to obtain with good atomizatio...

A temporal stability analysis was carried out to model the atomization of a swirling viscous annular liquid sheet emanating from an air-blast atomizer subject to inner and outer inviscid swirling air streams. The dimensionless dispersion equation that governs the instability of a viscous annular liquid sheet under swirling air streams was obtained. Numerical solutions to the dispersion equation...

In this work, tungsten coil (W-Coil) devices are used as atomizers for electrothermal atomization atomic absorption spectrometry (ETAAS), electrothermal atomization laser excited atomic fluorescence spectrometry (ETA-LEAFS), and electrothermal vaporization inductively coupled plasma atomic emission spectrometry (ETV-ICP-AES). For most cases in ETAAS and ETA-LEAFS, limits of detection (LODs) usi...

The in uence of fuel chemical composition on  ame structure and sooting trends in a swirling spray  ame was investigated semiquantitatively using a light-scattering/dissymmetry ratio technique. Binary mixtures of toluene and methanol were examined under Ž xed aerodynamic and burner inlet  ow conditions to show the effect of liquid composition. The sprays were generated using an air-assist a...

A new atomizer based on atmospheric pressure dielectric barrier discharge (DBD) plasma was specially designed for atomic fluorescence spectrometry (AFS) in order to be applied to the measurement of arsenic. The characteristics of the DBD atomizer and the effects of different parameters (power, discharge gas, gas flow rate, and KBH(4) concentration) were discussed in the paper. The DBD atomizer ...
