Deposition of colloidal- and nano-scale particles on surfaces is critical to numerous natural and engineered environmental, health, and industrial applications ranging from drinking water treatment to semi-conductor manufacturing. Nano-scale surface roughness-induced hydrodynamic impacts on particle deposition were evaluated in the absence of an energy barrier to deposition in a parallel plate ...

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...

The fri ctional force on a Brownian motion particle can be expressed by means of the time· correlation of the fluctuating force on the particle . We show that this method, applied to a spherical particle in a vi scous incompress ible fluid , leads to Stokes ' Law. The calculation is based on the theory of hydrodynamic flu ctuations due to Landau and Lifs hitz, and on a hydrodynamic theorem due ...

– Dissipative particle dynamics (DPD) and multi-particle collision (MPC) dynamics are powerful tools to study mesoscale hydrodynamic phenomena accompanied by thermal fluctuations. To understand the advantages of these types of mesoscale simulation techniques in more detail, we propose new two methods, which are intermediate between DPD and MPC — DPD with a multibody thermostat (DPD-MT), and MPC...

We consider the hydrodynamic behavior of some conservative particle systems with degenerate jump rates without exclusive constraints. More precisely, we study the particle systems without restrictions on the total number of particles per site with nearest neighbor exchange rates which vanish for certain configurations. Due to the degeneracy of the rates, there exists blocked configurations whic...

We carried out three-dimensional simulations, with about 1.4 × 10 particles, of phase segregation in a low density binary fluid mixture, described mesoscopically by energy and momentum conserving Boltzmann-Vlasov equations. Using a combination of Direct Simulation Monte Carlo(DSMC) for the short range collisions and a version of Particle-In-Cell(PIC) evolution for the smooth long range interact...

Process of quantum tunneling of particles in various physical systems can be effectively controlled even by a weak and slow varying in time electromagnetic signal if to adapt specially its shape to a particular system. During an underbarrier motion of a particle such signal provides a “coherent” assistance of tunneling by the multi-quanta absorption resulting in a strong enhancement of the tunn...

Abstract The CLVisc (3+1)D viscous hydrodynamic model is extended to include the equation of net baryon conservation and Israel-Stewart-like equations for dissipative current. Using NEOSB state, we simulate dynamical evolution collectivity quark-gluon plasma with finite chemical potential, assuming smooth energy density distributions at initial proper time. Numerical results are shown impact ne...

A general method for computing the hydrodynamic interactions among N suspended particles, under the condition of vanishingly small particle Reynolds number, is presented. The method accounts for both near-field lubrication effects and the dominant many-body interactions. The many-body hydrodynamic interactions reproduce the screening characteristic of porous media and the ‘effective viscosity ’...
