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...
And the CFD technology is a good method to simulate the movement of the particle in the emitter path;the reaction of the particles to the flow in the emitter was intense and should not be ignored in the simulation;according to the Stokes number compute results, some particles could not keep...

Under such a condition, gas bubbles ascend with a large velocity because they are accompanied by the up-flowing liquid. The large value of ub in the fluidized catalyst bed is considered to be due to a similar mechanism. Although the particle movement around a single bubble has been well ...

Mathematical Modelling of Particle Movement Ahead of the Solid—liquid Interface in Continuous Casting Whether the particle will be trapped by the solid-liquid interface or not is dependent on its moving behavior ahead of the interface, so a mathematical mod... HongLEI YongliJIN - 《材料科学技术(...
[342] use the Young-Dupré equation, for liquid droplets on a solid substrate, in the form of: (80)Γ*=γ1+γ2−γ12·cosΘc, where γ1 and γ2 are the surface energy (solids) or the surface tension (liquids) of the collision partners. The parameter γ12 is the interfacial ...
The two simulation techniques are fully coupled in both ways through interaction forces between the solid DEM particles and the fluid SPH particles. Thus this simulation method provides the possibility to simulate the individual movement of polyhedral, sharp-edged particles as well as the flow field ...
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 gases. Explain everyday effects of diffusion in terms of particles, e.g. th...
Manipulation of microscale particles and fluid liquid droplets is an important task for lab-on-a-chip devices for numerous biological researches and applications, such as cell detection and tissue engineering. Particle manipulation techniques based on surface acoustic waves (SAWs) appear effective for la...
