A 2D multiphysics model has been developed to simulate heterojunctions separating abruptly doped semiconductor layers of different dopant concentrations. Numerical results are presented for the case of nN, pN and PpN heterojunctions, and a general procedure for simulating multiple heterojunctions is described.

Center of Excellence for Communication Systems Technology Research, Texas
The motivation for this work is to explore the combination of a multiphysics COMSOL model of the wing of the Pathfinder Plus research aircraft with a wavelet-based vibration detection scheme. COMSOL Multiphysics is utilized to model the physics of the aerodynamics that produce vibration in the wing structure of the Pathfinder Plus. Next, three Daubechies wavelets are used to detect the ...

Hydrogen plasma is typically used in the semiconductor industry for materials processing, surface preparation and cleaning of silicon wafers and thin films. In this contribution, we developed a 2D/3D plasma fluid model as described by the set of the species and energy balance equations in a generic semiconductor tool chamber with remote Inductively Coupled Plasma (ICP) source. Background ...

Microwave sintering has been applied to a wide variety of, and recent experimental results have showed that for semi-metal or magnetic materials, the magnetic field (H) can have a significantly larger contribution than the electric field (E) during sintering. We have employed COMSOL Multiphysics to simulate the sintering process by adding the magnetic field contribution into the heating source. ...

We discuss the use of 3D grain continuum modeling to study grain boundary migration driven by differences in strain energy density. COMSOL Multiphysics is used to compute stresses and strain energy densities in polycrystalline structures caused by temperature changes. The grain boundary speeds are computed using a simple model that relates them to grain boundary mobility and differences ...

The combustion of lean methane in a catalytic flow reversal reactor (CFRR) is studied using COMSOL Multiphysics and a 2D continuum model. This model is based on mole and energy balance equations for the solid (the inert and catalytic sections of the reactor) and the fluid phases. The results show the impact on the methane conversion and the maximum temperature in the reactor of key ...

The dynamics of fuel cell coolant flow with charged nanoparticles were modeled using COMSOL Multiphysics. A computational fluid dynamics physicochemical model of the multi-phase coolant flow has been formulated. For nanoparticles in the fluid, electrokinetic force, hydrodynamic force, and buoyancy forces have been taken into account for the prediction of electrodeposition rate onto channel ...

A COMSOL Multiphysics 2D model of human tissue focuses on the change in dielectric properties (conductivity and permittivity) due to temperature, tissue type, blood flow, structure and other properties. These induced changes in dielectric properties result in significant changes in temperature and possible breakdown of the tissue. The result of this complex interaction is a feedback loop that ...

In this presentation we introduce the concept of Electrochemical Engineering through simulations in COMSOL Multiphysics. Our special case studies are: • a Parallel Plate Electrochemical Reactor, • a Rotating Ring Disk System, • a 3D Lithium Ion Battery, • a Portable Power System, • a Corroding Surface. These examples are all industrial ones, which shows the power of using ...
Study of the Electric Field Intensity in Bushing Integrated ZnO Surge Arresters by Means of Finite Element Analysis
Shahid Abbaspour (PWUT) University of Technology, Tehran, Iran
In this paper, the electric field in different types of ZnO surge arresters has been investigated by means of finite element modeling using COMSOL Multiphysics. Both conventional and novel built-in-bushing type arresters were studied. Electric field modeling helps designers consider important factors affecting the maximum field intensity in the arrester, avoiding damages to the arrester ...
