Interferometric techniques, which use information encoded in the Doppler burst resulting from the interaction of a particle with a two-beam interference pattern have become practical diagnostic tools for the analysis of complex, two-phase flows.

Droplet size control in liquid jet breakup
Physics of Fluids, 1996A Boundary Element Method (BEM) has been developed to investigate the nonlinear evolution of the surface of liquid jets injected from circular orifices under unsteady inflow conditions. For fixed wavelength perturbations, the model predicts the formation of main and satellite droplets. The size of the droplets is affected by changes in the perturbation

Micrometer-Sized Water Droplets Induce Spontaneous Reduction
Journal of the American Chemical Society, 2019Bulk water serves as an inert solvent for many chemical and biological reactions. Here, we report a striking exception. We observe that in micrometer-sized water droplets (microdroplets), spontaneous reduction of several organic molecules occurs, pyruvate to lactate, lipoic acid to dihydrolipoic acid, fumarate to succinate, and oxaloacetate to malate ...

Control of Droplet Size in Liquid Nanodispensing
Nano Letters, 2006In this Letter, the phenomena and parameters governing the nanoscale dispensing of liquid through an apertured atomic force microscope probe milled by focused ion beam lithography are characterized in detail. We show that the size of deposited droplets can be reproducibly defined by controlling the aperture size on the probe and the surface energies of

Applied Optics, 1995
A full-field, time-resolved interferometric method for the characterization of sparse, polydisperse spray systems is reported. The method makes use of the angular intensity oscillations in the wide-angle forward-scatter region. A pulsed laser is used to illuminate a planar sheet through the spray, which is imaged, out of focus, from the 45°direction ...

Collecting Supercooled Cloud Droplets as a Function of Droplet Size
Journal of Atmospheric and Oceanic Technology, 1992Abstract Supercooled cloud droplets were inertially impacted onto “cloud-sieves” at a mountaintop location. The large cross-sectional areas of the sieve meshes permitted grams of cloud water to be passively collected in minutes. Each sieve was constructed from specific diameter cylindrical strands and collected all cloud droplets larger than a critical

Droplet sizing with a wavelength modulated laser
Applied Optics, 2018The light scattered by spherical droplets much larger than the wavelength may be modeled with rays associated with scattering orders that follow the laws of geometrical optics. These rays travel different paths as they are reflected and refracted by the droplet.

Droplet size and shape effects in nematic droplet/polymer films
SPIE Proceedings, 1990Control over the operating voltage of nematic droplet/polymer films continues to be an important area of development in this class of devices. Our recent work in this area has included both materials modifications in order to alter the reorientation voltages of these films, as well as efforts to tie theory to experimental results.
