2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The governing equations are solved applying the COMSOL Multiphysics® interfaces Laminar flow, Electric Currents, ...

Selective Laser Melting (SLM) offers great potential for future manufacturing technology. In order to extend its applicability for the processing of high melting materials like molybdenum fundamental process understanding is required. This can be obtained by multiphysical simulations that allow a look into the process. In this contribution a thermo-fluiddynamical simulation model for laser beam ...

INTRODUCTION: Perfectly matched layers (PML) have been widely used for simulating wave propagation in unbounded media to effectively avoid spurious wave reflections from the computational domain boundaries. Time-domain PML formulations, especially for elastic waves, usually use a complex system of first-order equations. Compact second-order time-domain formulations are particularly desired ...

Indoor ventilation with good air quality control prevents infection with minimizing the spread of airborne respiratory and other infections in hospitals. CFD can be utilized to optimize flow pattern in clean rooms especially hospital clean rooms. More than two million people in Europe are infected due to Health-care Associated Infection (HAI) (Pittet et al., 2005). It is believed that transfer ...

Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality . PV researchers need an accessible and versatile simulation tool to optimize existing technologies and to reduce the time from concept to prototype for new technologies. This work demonstrates how ...

1. Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in  for forced convective heat transfer and in  for natural convection problems. In this work, topology optimization including density filtering and projection is applied to ...

Polymer hydrogels are commonly used as carriers or vehicles for the controlled release of drugs, primarily because of their bio-compatibility and because rates of drug release can be controlled by manipulating polymer properties like molecular weight, cross linking ratio, etc. Drugs can be released for prolonged periods of time through polymer hydrogels [1, 2]. Sustained drug release may ...

The accurate atomic potential determination is an essential task in the molecular simulations, e.g. Grand Canonical Monte Carlo (GCMC). The ab initio simulations using the quantum mechanics would of great interest in the computational physical chemistry. The numerical simulation of the adsorption phenomenon requires knowing the interactions parameters between the atoms that make up the systems ...

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper will focus on the prediction of the magnetic noise generated and radiated by a specific motor. The challenge is ...
