Evaluating the capabilities and uncertainties of droplet measurements for the fog droplet spectrometer (FM-100) [PDF]

Atmospheric Measurement Techniques, 2012
Droplet size spectra measurements are crucial to obtain a quantitative microphysical description of clouds and fog. However, cloud droplet size measurements are subject to various uncertainties.

Size‐Dependent Phase Separation in Emulsion Droplets [PDF]

ChemPhysChem, 2018
AbstractPhase separation occurs in emulsion droplets containing poly (ethylene glycol) diacrylate (PEGDA), glycerol, and ethanol to form a glycerol‐in‐PEGDA structure, and the phase separation process is found to depend on the droplet size. The mechanism of this size‐dependent phase separation is dependent on the droplet sizes changing the phase ...

Effect of Frequency on Droplet Characteristics in Ultrasonic Atomization Process [PDF]

E3S Web of Conferences, 2019
The study of ultrasonic atomization is one of the important factors for fuel spray process in the diesel engine combustion chamber. The droplet characteristics are influenced by liquid properties and vibration frequency.

Metastable lifetimes in a kinetic Ising model: Dependence on field and system size

, 1994
The lifetimes of metastable states in kinetic Ising ferromagnets are studied by droplet theory and Monte Carlo simulation, in order to determine their dependences on applied field and system size. For a wide range of fields, the dominant field dependence

SNEDDS Containing Poorly Water Soluble Cinnarizine; Development and in Vitro Characterization of Dispersion, Digestion and Solubilization

Pharmaceutics, 2012
Self-Nanoemulsifying Drug Delivery Systems (SNEDDSs) were developed using well-defined excipients with the objective of mimicking digested SNEDDSs without the use of enzymes and in vitro lipolysis models and thereby enabling studies of the morphology and

Using an Arbitrary Moment Predictor to Investigate the Optimal Choice of Prognostic Moments in Bulk Cloud Microphysics Schemes [PDF]

, 2019
Most bulk cloud microphysics schemes predict up to three standard properties of hydrometeor size distributions, namely, the mass mixing ratio, number concentration, and reflectivity factor in order of increasing scheme complexity.
