This presentation summarizes three different types of modeling using COMSOL Multiphysics. It is divided into three parts: Compressible flow, Multiphase flow, and Plasma Simulations. For the first part, we perform a special case study of the Mass Flow Verifier. A Mass Flow Verifier validates...

The work presented here deals with the simulation of the cavity filling stage of the injection and micro-injection molding process for thermoplastic materials.

COMSOL Multiphysics gives us the means to take into consideration some other aspects usually neglected in commercial 3D softwares...

With the recent improvement of X-ray Computed Tomography and robust modeling tools, it is now possible to show that pore scale fluid flow modeled by the Navier-Stokes equation can be used to derive macro parameters of Darcy’s Law, such as the hydraulic conductivity.

The model allows...

Since aerogel materials are open cell, inorganic foams, the surface pores of the material must be sealed for large scale application. Here we discuss the design and development of a spout fluid bed system for producing coated aerogel particle material. Comsol Multiphysics was used in...

Structure modelling and properties evaluation require high level modelling. In this paper, we demonstrate a composite made up of E-glass reinforcement and epoxy matrix. Both materials were assumed to be isotropic.

During injection moulding of thermoplastic parts, high pressures, velocities and temperatures are experienced by the polymer in the filling phase. The numerical simulation of this phase is a complex task, especially for semi-crystalline polymers, because it involves a coupling between heat...

In this paper, a study of the electronic properties of nanocrystals is presented. During this work, COMSOL Multiphysics has been used to develop various approaches to study the evolution of the floating potential of a single nanocrystal embedded in a dielectric medium.

First of all, we...

An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low...

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...

We report numerical simulations in which a 30 µm thick polymer membrane, glued over a submilimetric polymer chamber, is subjected to a homogeneous pressure over its entire surface. The deflections are obtained as a function of the applied pressure, and are further compared to experimental...
