particle movementsParticles floating in liquid metal can produce echoes of ultrasound. By evaluation of these echoes attempts are made to reconstruct the movements of the particles along the ultrasound path. That means the particle positions vertically above the ultrasonic transducer as functions of time...
This paper demonstrates particle tracking velocimetry performed for a model system wherein particle-laden liquid metal flow around a cylindrical obstacle was studied. We present the image processing methodology developed for particle detection in images with disparate and often low signal- and contrast-to...
Describe the solid, liquid and gaseous states of matter and explain their interconversion in terms of the kinetic particle theory and of the energy changes involved. Describe and explain evidence for the movement of particles in liquids and
A theoretical treatment of diffusion as function of turbulence, by working out the dispersion of small particles in turbulent fluid. The method of Kolmogoroff is used to decribe the movement in a statistical ways T Chan-Mou - Springer Netherlands 被引量: 420发表: 1947年 Simulated rain events ...
In this work, by means of extensive Molecular Dynamics simulations, we study the effects of the microscopic details and the thermodynamic state of the solvent on the movement of a single nano-colloid. In particular, we consider a two-dimensional model system in which the mass and size of the...
Movement of particles during scanning and roughness of the underlying substrate may complicate sizing. Several authors have explored the use of AFM for particle-size analysis [42–46]. The observed small differences between AFM and SEM have been interpreted to result from less-than-optimal tip ...
The colloidal particle in an electrolyte suspension is electrically charged in general. This may be of chemical nature such as the dissociation of functional groups on the particle surface when put in contact with a liquid solvent, or it may be of physical nature due to the adsorption of electr...
The particle movement is the result of the force exerted by the liquid on the surface of the particle. Therefore, hereinafter we are going to study the dependency of the hydrodynamic force on the particle size, which will allow to classify particles by their radii. In order to experimentally ...
PROBLEM TO BE SOLVED: To provide a particle movement type display device 100 in which memory property of image display can be improved without decreasing necessary properties and substantial functions of a layer such as a resistance layer 7 which is conventionally exposed to a movement space 20 of...
