The ability to confine and manipulate single particles in free solution is a key enabling technology for fundamental and applied science. Methods for particle trapping based on optical, magnetic, electrokinetic, and acoustic techniques have led to major advancements in physics and biology ranging from the molecular to cellular level. In this article, we introduce a new microfluidic-based techni...

Abstract The whole process of concrete slump experiment was simulated with Particle Flow Code 3 Dimensions (PFC3D) software based on discrete element simulation. simulation results are in good agreement the macroscopic obtained from field experiments, indicating that use PFC for had feasibility have a observation speed and direction particles slump.

Sediment transport over an erodible sediment bed is studied by particle resolved simulations with a hybrid parallel approach. To overcome the challenges of load imbalance in traditional domain decomposition method when encountering highly uneven distributions particles transport, approach Darmana et al.(2006) originally developed for point modified and implemented into simulations. A novel memo...

Previous work [51] showed how to solve time-fractional diffusion equations by particle tracking. This paper extends the method to the case where the order of the fractional time derivative is greater than one. A subordination approach treats the fractional time derivative as a random time change of the corresponding Cauchy problem, with a first derivative in time. One novel feature of the time ...

In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, Wettability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray d...

The plasma flow in the scrape-off layer (SOL) plays an important role for the particle control in magnetic fusion reactors. The flow is expected to expel Helium ashes and to retain impurities in the divertor region, if it is directed towards the divertor plate. It has been experimentally observed, however, that the flow direction is sometimes opposite; from the plate side to the SOL middle side...

Particle deposition/erosion can affect mirrors used in plasma diagnostics and this is a major concern for future fusion reactors. This subject is analyzed for the first and second mirrors of the proposed Motional Stark Effect edge plasma current diagnostic for ITER. Particle fluxes to the diagnostic module aperture are given by edge-plasma/impurity-transport solutions for convective plasma flow...
