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

Magnetic grippers are commonly used for workholding in handling and assembly of ferrous metalcasted parts. The workholding force produced by the magnetic gripper is strongly influenced by the texture and form of the workpiece in contact with its surface. This work explores the optimal ... 詳細を見る

Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have ... 詳細を見る

In this paper a thermal electric finite element method (FEM) analysis was used to investigate the thermal properties of individual electrically driven platinum micro-heaters. The geometric optimization for the micro-heater was performed by simulating a wide range of possible geometries ... 詳細を見る

Here we calculate opto-mechanically induced Surface Acoustic Waves upon a silica microresonator using COMSOL. Using conservation of momentum, we show both analytically and numerically that the photonphonon interaction within the resonator cavity causes a moving train of electrodes - a ... 詳細を見る

This paper presents the Finite Element Method technique for predicting performance of Induction motor having Electric and Magnetic asymmetry for rotor cage due to some broken rotor bars. The motor parameters like magnetic vector potential, flux density, surface currents have been ... 詳細を見る

Ferrimagnetic based, coaxial nonlinear transmission lines (NLTLs) provide a means to generate sub-nanosecond risetime pulses (from nano-second input pulses) or megawatt level high power microwave oscillations, depending on the geometry, material, and external bias fields. This ... 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

Phase gratings are used in many applications owing to their high transmission and thus higher diffraction efficiencies. COMSOL is based on finite element modeling and is chosen for 2 reasons; firstly, because it can handle complex 2-D and 3-D geometries and secondly, it can handle the ... 詳細を見る

MEMS(Microelectromechanical systems) based energy harvesting is process of extracting energy from natural resources in small amounts. Here, number of (millions) small energy harvesting modules lead to substancial energy. In this design, a piezoelectric material is used to scavenge ... 詳細を見る
