The self-induced ion plating (SIIP) process is a new physical vapor deposition process based on the evaporation of a metallic target (i.e. tin) thanks to a magnetron sputtering system. The aim of this work is to develop a numerical simulation model of the SIIP process in order to predict the target temperature field and from it, the coating profile on the substrate. The simulation of the SIIP ...

An energetic material, subjected to an abnormal thermal environment, can undergo cookoff involving a variety of thermal, chemical and mechanical processes. The ability to predict not only the time to cookoff reaction but also the site and the degree of reaction violence that will occur in an ammunition is the principal goal in the current cookoff modelling efforts. Considering our knowledge of ...

This paper investigates the modeling of styrene free radical polymerization in two different types of microreactor for which the wall temperature is kept constant. The simulations are performed with the help of FEMLAB 3.1 to solve simultaneously partial differential equations resulting from the hydrodynamics, thermal and mass transfer (convection, diffusion and chemical reaction). The ...

The flexibility of COMSOL Multiphysics enables a variety of computational approaches to be applied towards solving electromagnetic problems across the whole spectrum. I will describe techniques for studying resonant electromagnetic interactions in a range of structures, including materials with negative electric permittivity (metals at optical frequencies), and small microwave resonators and ...

Fluid and solute transport in hemodiafilter hollow fibers occurs through a non-trivial interaction of convection and diffusion, modulated by a number of factors that include the non-Newtonian behavior of blood, the density and viscosity dependence of blood on the local hematocrit and protein concentration, the Fahraeus-Lindquist effect on hematocrit, the osmotic effects of protein and partially ...
Electric Field Distribution in Biological Tissues for Various Electrode Configurations - A FEMLAB Study

Electroporation or Electropermeabilization (EP) is a non-viral physical process of inducing and/or increasing permeability of biological membranes by the application of high intensity and short duration electrical pulses. The resulting high field strength in the membrane can lead to the formation of regions of increased permeability, often called pores that allow transmembrane transport of ...

The axon in one of the most important components in nervous impulse transmission. It is very important to understand how the electric potential changes along the axon, using the telegraph equation. In the following simulation with FEMLAB we show the transmission and diffusion along the axon in 3D when a squared voltage is applied. The simulation is used for educational purposes in ...

Multiphysics phenomena that occur when metering coating colours between paper and a composite polymeric-steel blade are simulated in this paper. The paper discusses modelling requirements for coating process technologies that have been fulfilled using the FEMLAB software, as well as requirements that still need to be modelled in order to accurately simulate the complex interdependent ...

Free convection in a vertical square cavity filled with a fluid saturated porous medium is investigated numerically by means of the software package FEMLAB 3.1i. The cavity has isothermal walls and is heated by an internal concentric circular boundary subjected to a uniform heat flux. The porous medium satisfies the Darcy law and the validity of the Boussinesq approximation is ...

The ability of an industrial mixing tank to homogenize its contents decays rapidly as the Reynolds number is decreased in the transitional regime and approaches the laminar regime. A model of a mixing tank was developed using FEMLAB and using a CFD technique known as momentum source modelling. The model predictions of velocity components agree well with LDA measurements. Decolorization ...
