The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface electrode in the 3D Electrostatics application mode of COMSOL Multiphysics® 3.5a. The values of the electric ...

Introduction: The use of microwave energy for thermal cracking (from thermal stress and water pore pressure) of lignite-coal briquettes increases the lignite friability  and is beneficial for later chemical treatment inside a gasifier (for methanol production for example). An adequate use of microwave energy can improve the overall efficiency of the gasification process based on lignite ...

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle wax leads to a phase change that allows mass transport via capillary flow prior to combustion in the flame. ...

Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very challenging due to the multiplicity of the CVD growth conditions. COMSOL Multiphysics® software is used to investigate ...

This paper presents the 3D model of hydrodynamic plain journal bearing using COMSOL Multiphysics®. Using 3D Model, pressure distribution in plain journal bearing is obtained by steady state analysis of plain journal bearing. Generalized Reynolds equation is used for analyzing hydrodynamic journal bearing by COMSOL Multiphysics® as well as by analytical method by applying Sommerfeld boundary ...
Exploratory FEM-Based Multiphysics Oxygen Transport and Cell Viability Models for Isolated Pancreatic Islets
Diabetes Research Institute and the Department of Molecular and Cellular Pharmacology, University of Miami, Miller School of Medicine, Miami, FL, USA
Cellular-level oxygen consumption and cell viability models incorporating physiologically realistic assumptions and fully scaled 2D/3D geometries have been implemented in COMSOL Multiphysics for isolated pancreatic islets. Oxygen consumption was assumed to follow Michaelis-Menten–type kinetics and to cease when local concentrations fell below a critical threshold. Results are in good agreement ...

The interaction of a single particle in straight rectangular channel in laminar flow is modelled explicitly using the set of Navier Stokes equation for the fluid motion and Newton momentum equation for the particle motion in Cartesian coordinate system. The evaluation of integral force acting on the particle along with the behaviour of streamlines as a function of Reynolds number ReP < 120 is ...

Radio Frequency MEMS devices have emerged to overcome the problem of high losses associated with semiconductors at high frequencies. A tunable MEMS capacitor is a micrometre-scale electronic device whose capacitance is controlled through different actuation mechanisms which govern the moving parts. It can have electrostatic or electrothermal actuators depending on the functional complexity and ...
