In agricultural spray application of pesticides, the volumetric droplet size distribution (VDSD) critically influences the efficacy of the application as well as the risk of off-target spray deposition. It is critical to have accurate predictions of

A method for obtaining the elasticity, surface tension, and viscosity of ultrasonically levitated gel drops is presented. The drops examined were made of agarose, a hydrogel. In contrast to previous studies where fluid properties are obtained using u

This study concerns the effects of pressure, spatial location, and application of oil emulsions on the resulting droplet size, eccentricity, as well as velocity distributions, all of which are crucial information in determining the dispersion dynamic

Herein, we experimentally study the role of boom height in the downwind deposition of agricultural sprays using a boom-scale, low speed, recirculating wind tunnel. A section of a John Deere spray boom fitted with 4 nozzles was mounted at 0.5 m and 1

The measurements of size distribution of small particles (e.g. dusts, droplets, bubbles, etc) are critical for a broad range of applications in environmental science, public health, industrial manufacturing, etc. Laser diffraction (LD), a widely used

We report experimental observations of surface oscillations in an ultrasoft agarose gel drop. Ultrasonic levitation is used to excite shape oscillations in the gel drop and we report the natural frequency of the drop as it depends upon a nondimension

During the spray process, many factors control the disintegration of the liquid sheet at the exit of a nozzle operating in an ambient atmosphere. Understanding the role of these parameters has significant implications on the spray quality. In particu
