Our Institute at the West Hungarian University is dealing with modelling of heat physical treatments in agricultural (biological) materials. The essential key in order to gain accurate results is to know the driving forces during heat and mass transfers. In case of mass transfer ... 詳細を見る

Within the field of hot metal bulk forming the demand arises for fully three-dimensionally tailored properties at the microstructural level, nevertheless, reaching a predefined geometry with such tailored properties puts high requirements on the control mechanisms utilized in the process ... 詳細を見る

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 ... 詳細を見る

A number of visualization experiments are carried out at the laboratory temperature with oil, brine and bacteria suspension for evaluating the performance of MIOR in a glass micromodel. The observations show the effects of bacteria on remaining oil saturation. The interfacial tension ... 詳細を見る

The aim of the study is to predict the formation of porosities in the case of spot laser welding of tantalum. During the interaction, a deep and narrow cavity, called the keyhole, is generated. At the end of the interaction, surface tension provokes the collapse of the keyhole. Gas ... 詳細を見る

We present examples of the use of COMSOL Multiphysics for the solution of electrical conduction in varistors coupled to the solution of long-term heat-transport through conduction and convection. We fit measured power-loss and impedance data with analytic functions in order to simulate ... 詳細を見る

This paper describes a numerical solution method for the simulation of a cold crucible induction melting (CCIM) process involving the coupling of electromagnetic, temperature and turbulent velocity fields. During the CCIM process, the metal charge is contained on a water cooled ... 詳細を見る

A simple magnetic circuit consisting of ferromagnetic core material, air gap, permanent magnets and current coils can be used to form magnetic actuators, motors etc. devices. In this work the current coils are not used to generate working magnetic field, but just to switch magnetic flux ... 詳細を見る

This work presents a different use of COMSOL as an integrated component of a computational tool framework used to automate designs creation. CNS-Burst is a computational synthesis method that has been implemented with the aim of automatically generating solutions to an assigned design ... 詳細を見る

3D FEM simulation of millimeter-scale, complex electro-optically induced waveguide based devices demands the use of grids with more than several million nodes. Hence the simulation could take substantial time and require large amounts of available memory. This paper presents a ... 詳細を見る
