The Filament Extension Atomization Process for Powder Production of Elastic Fluids

open access: yesChemie Ingenieur Technik, EarlyView.
Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.

Rayleigh-wave frequency discriminator

open access: yesElectronics Letters, 1972
A frequency discriminator using two Rayleigh-wave filters and two rectifying networks is described. For each filter, one of the transducers has a finger length varying according to a (sin x/x)2 law, so that the frequency response is almost triangular. The central frequencies of the two filters are different.

Short-Time Existence for Scale-Invariant Hamiltonian Waves

open access: yes, 2005
We prove short-time existence of smooth solutions for a class of nonlinear, and in general spatially nonlocal, Hamiltonian evolution equations that describe the self-interaction of weakly nonlinear scale-invariant waves. These equations include ones that

The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Attenuated leaky Rayleigh waves [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1993
The propagation of leaky Rayleigh waves under the influence of viscous damping and heat conduction in boundary layers is studied using the matched asymptotic method. Viscosity of the fluid is considered unimportant except in a thin viscous boundary layer at the interface.

Nanoparticles in microdroplets: Recent advances in microfluidic generators for producing functional microbeads

open access: yesDroplet, EarlyView.
Functional hybrid microbeads with electrical, magnetic, and/or optical responsiveness have emerged as versatile platforms for biotechnology. This review highlights recent advances in microfluidic technologies for producing such microbeads, with a focus on incorporating functional nanoparticles in microdroplet systems.

Subcritical scattering from buried elastic sphere based on subsonic Rayleigh waves

open access: yesJournal of Ocean Engineering and Science
This study investigates the scattering characteristics of a buried elastic sphere under plane wave subcritical incidence at low-frequency. As the penetrating wave in sediment at subcritical angles transitions to an evanescent wave, it decays along the ...

Formulas for the H/V ratio of Rayleigh waves in incompressible pre-stressed half-spaces

open access: yesArchives of Mechanics, 2018
In this paper, the propagation of a Rayleigh wave in an incompressible pre-stressed elastic half-space is considered. The main aim is to derive exact formulas for the H/V ratio, the ratio of the amplitude of the horizontal displacement to the amplitude ...

Ambient noise multimode Rayleigh and Love wave tomography to determine the shear velocity structure above the Groningen gas field

open access: yesSEG technical program expanded abstracts, 2019
The Groningen gas field is one of the largest gas fields in Europe. The continuous gas extraction led to an induced seismic activity in the area. In order to monitor the seismic activity and study the gas field many permanent and temporary seismic ...
