Effect of density ratios on droplet breakup for newtonian and power-law fluids

International Journal of Multiphase Flow, 2023
The study investigates the impact of the density ratio [Formula presente] on droplet breakup for non-Newtonian fluids using numerical simulations. An in-house solver based on OpenFOAM version 4.x libraries and coupled Level Set - Volume of Fluid method for interface capturing is employed.

Density measurements on levitated liquid metal droplets

International Journal of Thermophysics, 1996
Electromagnetic levitation is a useful tool for measuring thermophysical properties of high-temperature melts such as liquid metals. Due to its noncontact nature, the undercooled regime is also accessible. Density and thermal expansion of a levitated drop can be derived from volume measurements, if its mass is known.

Size and density control of In droplets at near room temperatures

Nanotechnology, 2009
We report on the ability to control the size and density of In droplets on GaAs(100) substrates at near room temperatures using solid source molecular beam epitaxy. We specifically demonstrate the height, diameter and density control of In droplets as functions of substrate temperature (T(sub)) and monolayer (ML) coverage.

A droplet-based electricity generator with high instantaneous power density

Nature, 2020
Extensive efforts have been made to harvest energy from water in the form of raindrops1-6, river and ocean waves7,8, tides9 and others10-17. However, achieving a high density of electrical power generation is challenging. Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low

Density-Functional Theory of Quantum Droplets

Chinese Physics Letters
Abstract In quantum droplets, the mean-field energy is comparable to the Lee-Huang-Yang (LHY) energy. In the Bogoliubov theory, the LHY energy of a quantum droplet has an imaginary part, which has been neglected in most studies for practical purposes.

Vapour density field of a population of cloud droplets

Journal of Atmospheric and Solar-Terrestrial Physics, 2011
The idea that a cluster of droplets evaporates in times longer than a single droplet and that the droplets near the edge of the cluster evaporate most rapidly is based on observational evidence. In this work, we use a theoretical model based on the electrostatic-image-charge method to calculate the vapour density field for a cloud of monodisperse cloud

High-Density Droplet Microarray of Individually Addressable Electrochemical Cells

Analytical Chemistry, 2017
Microarray technology has shown great potential for various types of high-throughput screening applications. The main read-out methods of most microarray platforms, however, are based on optical techniques, limiting the scope of potential applications of such powerful screening technology.

Ordering and stability in lipid droplets with applications to low-density lipoproteins

Physical Review E, 2014
In this article, we present a framework for investigating the order-disorder transition in lipid droplets using the standard Ising model. While a single lipid droplet is itself a complex system whose constituent cholesteryl esters each possesses many degrees of freedom, we present justification for using this effective approach to isolate the ...

Droplet density, droplet size, and wavelength effects in PDLC light scattering

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1995
Abstract The transmission properties of several scattering-type PDLC films are studied as a function of droplet density, droplet size, wavelength, and applied field. Experimental scattering cross sections for the nematic droplets are compared to theoretical cross sections calculated using the anomalous diffraction model for light scattering.
