Direct observation of electric charges at solid/liquid interfaces with the pressure-wave-propagation method
نویسندگان
چکیده
Development of intrinsic electric charges at solid/liquid interfaces is still not fully understood and may generate large industrial damages by electrostatic discharges due to flow electrification. The pressure-wave-propagation (PWP) method used study in flowing conditions. Experimental results are shown with aluminum, brass, copper or pressboard contact demineralized water, salted glycerol mineral oil. Salted water presents larger charge extent than expected. In conditions glycerol, gives more has the largest extent. conditions, signal decrease seems attributed physico-chemical time constant.

Direct observation of carbon nanostructure growth at liquid-solid interfaces.
Our TEM observation revealed that in a carbon-Pt3Co system, amorphous carbon first crystallized into nanoclusters at step-edges on melting Pt3Co surfaces before merging into graphene layers through a kinetic restructuring via oriented-attachment, leading to the final formation of few-layered graphene nanostructures. The result obtained from density-functional theory calculations further suggest...
متن کاملSeismic Wave-Field Propagation Modelling using the Euler Method
Wave-field extrapolation based on solving the wave equation is an important step in seismic modeling and needs a high level of accuracy. It has been implemented through a various numerical methods such as finite difference method as the most popular and conventional one. Moreover, the main drawbacks of the finite difference method are the low level of accuracy and the numerical dispersion for l...

The reflection and transmission of thermoelastic plane waves at an imperfect boundary of two dissimilar fibre-reinforced transversely isotropic thermoelastic solid half-spaces under hydrostatic initial stress has been investigated. The appropriate boundary conditions are applied at the interface to obtain the reflection and transmission coefficients of various reflected and transmitted waves wi...
متن کاملSimulation of Wave Propagation over Coastal Structures Using WCSPH Method
In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
متن کاملWave Propagation at an Interface of Elastic and Microstretch Thermoelastic Solids with Microtemperatures
In the present paper, the problem of reflection and transmission of waves at an interface of elastic and microstretch thermoelastic solids with microtemperatureshas been studied. The amplitude ratios of various reflected and transmitted waves are functions of angle of incidence and frequency of incident wave. The expressions of amplitude ratios have been computed numerically for a particular mo...
