We present COMSOL-based analyses and design optimizations of a micromachined wind sensor. The sensor relies on eight germanium thermistors embedded in a thin silicon nitride membrane, where two orthogonally arranged ensembles, each consisting of four thermistors, are connected to form a ... 詳細を見る

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation ... 詳細を見る

The extensional flow of viscoelastic flow is encountered during fibre spinning processes. A variety of polymers such as polyesters, polyacrylonitrile, rayon, acrylic, spandex etc are manufactured using this process. In the spinning process, polymer melt/ solution is extruded in the form ... 詳細を見る

Bread is a food product which various complex physico-chemical phenomena occur during the cooking process. Thus, phenomena of heat and mass transfer are coupled to the deformation. In addition, bread is a multiphase product (solid, liquid and vapor) and composed of various components ... 詳細を見る

Anthropogenic mercury (Hg) emissions increase the risk of neurological and neonatal health effects in humans through fish consumption. There are several technological approaches to controlling mercury emissions from coal combustion, including the injection of a powdered mercury sorbent ... 詳細を見る

This talk is for intermediate-level users of COMSOL who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. Most turn-key Computational Fluid Dynamics packages, including COMSOL ... 詳細を見る

Relative permeability maps for steady-state two-phase flow in porous media, delivered by implementing the DeProF model [1] algorithm, were integrated within COMSOL Multiphysics® software [2] to resolve field-scale flows in porous media. The mechanistic model DeProF [1], predicts the ... 詳細を見る

Railgun is an electrically-powered gun that accelerates a conductive projectile along magnetic metal rails. Various factors increase the projectile velocity. Each method has its own advantages and disadvantages. While increasing the projectile velocity, one has to keep in mind the ... 詳細を見る

Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... 詳細を見る

There is limited option for non-intrusive flow measurement of liquid metals at high temperature. Liquid metal flowing in a conduit along with the transverse magnetic field induces emf in the liquid metal. The emf developed; which has linear dependency on flow velocity; can be used for ... 詳細を見る
