the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...

The effect of geometry and material of the Micro/Nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. Hertz contact model simulation for EpH biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. Then, to val...

The sensitivity analysis of atomic force microscope (AFM) based manipulation of gold spherical nanoparticles in air medium has been carried out in previous research works. In the AFM-based manipulations conducted in various biological liquid mediums, the new environmental parameters associated with these biological fluids also affect the dynamics of the manipulation process. Therefore in this r...

Let A be a set of trivariate irreducible integral polynomials and let D be an A-invariant cylindrical algebraic decomposition (cad) of three-dimensional space. This paper presents a new algorithm for determining the interstack adjacencies in D over a given non-nullifying (for A) 0-cell, 1-cell adjacency in the cad D 0 of the plane induced by D. We show that this new adjacency algorithm for thre...

Electrophoresis of a cylindrical particle placed between two parallel walls is considered for arbitrary eccentricity. The electric field is perpendicular to the particle axis, and both the particle and walls are non-conducting. The electrical double layers adjacent to the solid surfaces are assumed to be thin with respect to the particle radius and to the particle–wall gap. A boundary-element m...

Limiting currents in planar crossedeld diodes have been studied for over 70 years [1][3] for B < BHull and more recently for B > BH [4]. Recent simulations of cylindrical crossedeld diodes for anode/cathode radius ratios of 2 and 5 indicate that the limiting current curve in cylindrical diodes follows the planar theory and simulations very closely [5]. Newer simulations for larger radius ratios...

Submitted for the DPP15 Meeting of The American Physical Society A spectral, quasi-cylindrical and dispersion-free Particle-In-Cell algorithm1 REMI LEHE, LBNL, MANUEL KIRCHEN, DESY, Germany, IGOR ANDRIYASH, LOA, France, BRENDAN GODFREY, University of Maryland, JEAN-LUC VAY, LBNL — Particle-In-Cell (PIC) codes are widely used today for laser-wakefield acceleration and other laser-plasma interact...

When particles adsorb at a fluid/fluid interface at a sufficiently high concentration, the interface loses mobility and displays solidlike characteristics, a phenomenon called "interfacial jamming". Jamming can arrest interfacial tension-driven morphological coarsening in liquid/liquid or gas/liquid systems and therefore stabilize two phase morphologies with unusual interfacial shapes, for exam...

Electrokinetic transport of cylindrical cells under dc electric fields in a straight microfluidic channel is experimentally and numerically investigated with emphasis on the dielectrophoretic (DEP) effect on their orientation variations. A two-dimensional multiphysics model, composed of the Navier-Stokes equations for the fluid flow and the Laplace equation for the electric potential defined in...
