a novel computational fluid dynamics and molecular kinetic theory (cfd-mk) method was developed to simulate the impingement of a nanodroplet onto a solid surface. a numerical solution of the navier–stokes equation using a volume-of-fluid (vof) technique was used to model nanodroplet deformation. dynamic contact angle during droplet impact was obtained by molecular kinetic theory. this dynamic c...

this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

In chemical systems formed by living cells, the small numbers of molecules of a few reactant species can result in dynamical behavior that is discrete and stochastic, rather than continuous and deterministic (McAdams & Arkin, 1999; McAdams & Arkin, 1997; Arkin et al., 1998; Elowitz et al., 2002; Fedoroff & Fontana, 2002). By “discrete”, we mean the integer-valued nature of small molecular popul...

Abstract. This chapter is a review of the research of the authors from the last decade and focuses on the mathematical analysis of the Schrödinger model for nano–scale semiconductor devices. We discuss transparent boundary conditions (TBCs) for the time–dependent Schrödinger equation on a two dimensional domain. First we derive the two dimensional discrete TBCs in conjunction with a conservativ...

Focussing on those areas of simulation which dominate the large-scale computational requirements within the automotive industry, the initial aim of the paper is to give an insight into typical applications and algorithms being used. Beyond this, the main emphasis will be on the more recent developments related to the take-up of HPC technology in the form of the distributed-memory, message-passi...

Utility engineers and consultants use relay models to select the relay types suited for a particular application, and to analyze the performance of relays that appear to either operate incorrectly or fail to operate on the occurrence of a fault. Instead of using actual prototypes, manufacturers use relay model designing to expedite and economize the process of developing new relays. Electric po...

• Numerial simulation of spreading drops on a wettable surface. • We discuss the effect of the main parameters (density, viscosity, surface tension, drop radius and wettability). • Power law evolutions observed in experiments (t/2, t/10) are recovered and discussed. • The combined effect of viscosity and wettability has a significant effect on the spreading.

We present numerical simulations, obtained with the Versatile Advection Code, of the oscillations of an inverse polarity prominence. The internal prominence equilibrium, the surrounding corona and the inert photosphere are well represented. Gravity and thermodynamics are not taken into account, but it is argued that these are not crucial. The oscillations can be understood in terms of a solid b...

We present an effective numerical approach to simulate electrochemically mediated desalination of seawater. This new membraneless, energy efficient desalination method relies on the oxidation of chloride ions, which generates an ion depletion zone and local electric field gradient near the junction of a microchannel branch to redirect sea salt into the brine stream, consequently producing desal...
