To analyse the electric arcs in detail, and estimate the resulting vaporization from the increasing current, a multiphysics model which couples current flow, fluid flow, and heat transfer, based on balance equations, is established in COMSOL. The simulation results will show the electric arc ...

Transient 3D simulation performed with COMSOL Multiphysics, showing the magnetic flux density in the actuator. Image courtesy of ABB. ABB validated their simulation by checking when the holding force of the model matched the actual recloser, or by checking the coil’s current and voltage. They wer...

magnetics and electrics in COMSOL Multiphysics finite element software. Under the action of an external magnetic field, the steady-state solutions and the frequency-domain perturbation solutions related to the electric, magnetic and elastic fields of the P/T and T/P structures are obtained. The cur...
Figure 2a is the setup of the laminar flow module in COMSOL, which can simulate single-phase flow and two-phase flow in pressure drive, and the numerical simulation is performed according to Navier–Stokes equations given below: (12) (13)where indicates that the fluid in the microfluidic ...
In order to account for these factors, engineers must accurately analyze ISFET designs while taking into account the chemical reactions and electromagnetics phenomena, and more. TheCOMSOL Multiphysics® software, along with the Semiconductor Module and either the Microfluidics Module or a chemical engine...
Applied positions of equations and boundary conditions shown in Section 2.1, Section 2.2, and Section 2.3 are given in Fig. 3. FEM is adopted to solve the equations via COMSOL MULTIPHYSICS. The ‘Physics-controlled mesh’ was chosen as the sequence type with the element size of extra fine. ...
