Ion-selective membranes can be used in lab-on-a-chip devices for various portable applications in this field. These devices can be used as concentrators for analytical chemistry and for micro-scale filtration. Here, a binary aqueous electrolyte solution in a microchannel has a potential ... Read More

AC electrothermal (ACET) micropumps are based on the temperature gradient caused by Joule heating or an external heat source in the bulk of an electrolyte. In this paper, a 2D simulation was performed to study the effect of substrate thickness and material (glass and silicon) for an ACET ... Read More

Syntactic foams are hollow particle filled composites that have recently emerged as attractive materials for use in advanced structural applications in aerospace and defence industry. Ultrasonic characterization of these foams is performed extensively in order to understand the effect ... Read More

This paper presents the multiphase 2D axisymmetric simulation of a three-dimensional flow-focusing microfluidic droplet generator using the laminar two phase flow, phase field interface in COMSOL Multiphysics®. The performance of the device is characterized at different flow conditions. ... Read More

Electrochemically-active conducting polymers (ECP) swell or shrink in response to ion and solvent incorporation or ejection as a result of electrochemical reaction of the polymer. When anodic potential is applied to an electrode attached to one end of ECP strip, the oxidation process ... Read More

An Ion Mobility Spectrometer is a device to analyze different components of a gas mixture. A feature of this technology is the ultra-low detection limit which can be obtained for most trace gases. Due to a limited resolution which is needed to differ between different components an ... Read More

This work describes a model for plasma formation in the keyhole and above the EBW zone. The parameters of the plasma are closely connected to the characteristics of the thermal action of the electron beam on the welded metal, which allows operational control and study of EBW. The ... Read More

Introduction The COMSOL Multiphysics® software and its CFD Module have a physics interface for solving Laminar Two-Phase Flow problems using the Level Set method (1). This paper discusses how the tool may be used with more than two phases when the flow is laminar. It then introduces a ... Read More

At present, no 3D transient magnetic and electric fields formulation with strong eddy currents and high electric fields is available in the physical applications with COMSOL Multiphysics® software. However, some industrial products need such a tool, as it is the case for induction coils ... Read More

Atherosclerosis in arteries is caused by the formation of stenosis : fatty depositions, on the artery wall. In current medicine, the practice is to observe the maximum percentage occlusion at any arbitrary cross-section and diagnose the patient on that basis, which might not always ... Read More
