Theory of Proportional Solenoids and Magnetic Force Calculation Using COMSOL Multiphysics

O. Vogel, and J. Ulm
Heilbronn University
Campus Künzelsau
Künzelsau, Germany

Proportional solenoids are well-known and used in a wide range of applications today. This paper is about methods of influencing the characteristic force-stroke-curves of magnetic actuators by means of different pole geometries. The conical design of the stator pole which is mostly used ... Saiba Mais

Classical Models of the Interface Between an Electrode and an Electrolyte

E. Gongadze[1], S. Petersen[1], U. Beck[2], and U. van Rienen[1]
[1]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany
[2]Institute of Electronic Appliances and Circuits, University of Rostock,
Rostock, Germany

The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface ... Saiba Mais

The Design of a Multilayer Planar Transformer for DC/DC Converter with a Resonant Inverter new

M. Puskarczyk[1], R. Jez [1]
[1]ABB Corporate Research Center, Krakow, Poland

Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis ... Saiba Mais

Analysis of Burning Candle

J.S. Crompton, L.T. Gritter, S.Y. Yushanov, and K.C. Koppenhoefer
AltaSim Technologies LLC, Columbus, OH, USA

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle ... Saiba Mais

On the Simulation of Electromagnetic Forming Process of a Tube using Multiphysics Software

S. Gawade[1], P. P. Date[2], and S. B. Sharma[1]
[1]Production Engineering. Dept. SGGS IE&T, Nanded, India
[2]Mechanical Engineering. Dept, IIT, Bombay, India

Electromagnetic forming (EMF) is a typical high speed forming process using the energy density of a pulsed magnetic field to form workpieces made of metals with high electrical conductivity like e.g. aluminium. This forming process can be very advantageous as compared to conventional ... Saiba Mais

Heat Transfer and Phase Change Simulation in COMSOL Multiphysics® Software

N. Huc [1]
[1] COMSOL France, Grenoble, France

This session is devoted to phase change modeling in heat transfer simulations. The great interest in phase change comes from the outstanding thermal performance that it enables in particular for cooling or thermal protection applications. Alternatively, phase change can induce most of ... Saiba Mais
