COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... Per saperne di più
A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... Per saperne di più
Damping is the liminting factor for the reachable maximum deflection. Thus, it is a very important issue for resonant microsystems. In this paper, we present a damping model for out-of-plane comb driven resonant micromirrors. The basic concept of this model is to attribute viscous ... Per saperne di più
We use COMSOL Multiphysics to solve time-dependent optimal control problems for partial differential equations whose optimality conditions can be formulated as a PDE. For a class of linear-quadratic model problems we summarize known analytic results on existence of solutions and first ... Per saperne di più
Hybrid laser-MIG arc welding has very interesting advantages compared to laser welding or arc welding used separately. It is known that improvement of productivity results in higher welding speeds, thicker welded materials, joint fit-up allowance, better stability of molten pool, and ... Per saperne di più
We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using ... Per saperne di più
The objective of this work has been to realize a feasibility study of a cooling device for a SQUID sensor using liquid nitrogen flowing through micro channels. The design consists of an epoxy cylindrical vacuum vessel skewed by a silicon microchannel heat sink. The SQUID sensor is ... Per saperne di più
The Levitron offers an interesting demonstration of natural magnetic levitation using permanent magnets. It is composed by a small magnetized top and a circular magnetized base with a hole on its center. The top is placed in an area where magnetic field configuration and gyroscopic ...

The frequency dependent electrical impedance of porous media is studied by modelling the charge transport in the electrolyte filled pore space using COMSOL Multiphysics. The corresponding experimental method, called Spectral Induced Polarization (or Impedance Spectroscopy), shows a ... Per saperne di più
Metal hydrides are a widely-used method for storing and releasing hydrogen chemically under moderate conditions. This paper will present how highly dynamic metal hydride storage has been simulated and optimized using COMSOL Multiphysics. It will be shown how mass, energy and momentum ... Per saperne di più
