Over the last three years, COMSOL Conferences have been held at numerous locations throughout the world. Each year we have produced a user presentation and proceedings CD containing material presented at that year's COMSOL Conference. In total we have published over 750 papers so far.

• Benchmarking COMSOL Multiphysics 3.4
  Darrell Pepper
  Professor of Mechanical Engineering
  Director of the Nevada Center for Advanced Computational Methods (NCACM)
  University of Nevada, Las Vegas
  Las Vegas, NV
  
  In this presentation, four benchmark problems are tested using COMSOL Multiphysics as well as other commercial software packages, comparing their performance. This is done for fluid-structure interaction, fully coupled electronic current conduction with thermal and structural analysis, electromagnetic wave propagation and electric generators. Results compared with data in the literature show go...
  
  
  
• Solidification of a Liquid Metal Droplet Impinging on a Cold Surface
  T. L. Marin
  
  A method for the solidification of a free surface liquid phase is presented and solved with COMSOL Multiphysiscs using a fixed grid. In this case, the Level set method with phase re-injection for mass conservation is used to prescribe the movement of the free surface of the liquid droplet, whereas a modified version of the method presented by Voller and Prakash is used to account for the solidi...
  
  
  
• Using Coupling Variables to Solve Compressible flow, Multiphase flow and Plasma Processing Problems
  D. Smith MKS Instruments
  
  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 accuracy of a Mass Flow Controller by measuring the rate of change of pressure in a fixed volume. In...
  
  
  
• Finite element models for the solution of underwater acoustics problems
  Mario Zampolli NATO Undersea Research Centre La Spezia, Italy
  
  Acoustic waves are used in SONAR systems for the detection and classification of objects which may be swimming in the water column, proud on the seafloor, or buried below the sediment. In some applications, such as low frequency detection and classification of structurally complex objects immersed in a fluid, signal processing techniques must be aided by a-priori model based knowledge of the targe...
  
  
  
• Modeling Remote H₂ Plasma in a Semiconductor Processing Tool
  J. Brcka TEL Technology Center, America, LLC
  
  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 H...
  
  
  
• Indoor Air Quality Modeling
  D. Pepper University of Nevada, Las Vegas
  
  In this presentation we consider the modeling of indoor air quality, and pollutant transport. Today's aspects of indoor air quality unfortunately must include the potential risk of an attack with biological weapons. In this presentation, we illustrate the effect of such an attack. In the present work, we also present numerical results for indoor air quality for a specific building, namely t...
  
  
  
• Modelling and Design of the Solid Oxide Fuel Cell Anode
  K. Tseronis[1], I. Kookos[2], and K. Theodoropoulos[1] [1] University of Manchester [2] University of Patras, Greece
  
  A multidimensional, multicomponent, isothermal and dynamic model has been developed. It simulates the mass transport phenomena taking place in the fuel/air channel, the porous electrodes and the electrolyte of a planar SOFC. It allows prediction of the species composition profiles throughout the SOFC. For the numerical solution of the model equations, the finite element based software packa...
  
  
  
• Simulation of Blood Flow through the Mitral Valve of the Heart
  D.M. Espino[1], M.A. Watkins[1], D.E.T. Shepherd[1], D.W.L. Hukins[1], and K.G. Buchan[2] [1] University of Birmingham [2] Aberdeen Royal Infirmary
  
  A two-dimensional FSI model of the mitral valve was generated, using an ALE mesh, where valve closure was simulated using contact equations. The simulation predicted a large vortex behind the anterior leaflet during inflow of blood into the left ventricle, in agreement with MRI scans available in the literature. Leaflet deformations agreed with results from experiments in the literature and wit...
  
  
  
• Theoretical Modeling of a Thermophotovoltaic System
  Mattarolo, G., Bard, J. ISET, Institut für Solare Energieversorgungstechnik, Kassel
  
  Thermophotovoltaic (TPV) is an emerging technology based on the direct conversion of thermal radiation coming from a heat source into electricity by using photovoltaic (PV) cells. The first target for the TPV research is to break the threshold of 10% of efficiency, which would allow to start the commercialization of such technology in different applications. Defining and simulating a theoretic...
  
  
  
• Modeling of an LTCC mixer/combustor
  Espinoza Vallejos, P.A.1, Furlan, R.2, Sotero-Esteva, J.2, Perez Tolentino, M.2, Wagner Simoes, E.3, Santiago-Aviles, J.J.4 1 Technology Assessment and Transfer, Millersville, MD 2 University of Puerto Rico at Humacao, Humacao, PR 3 Laboratory of Integrated Systems of the University of Sao Paulo, Brazil 4 University of Pennsylvania, Philadelphia, PA
  
  The high energy density of some fossil fuels makes them attractive to power portable devices through the use of thermoelectric conversion elements. The idea explored here is the fabrication of a ceramic combustor using Low Temperature Co-Fired Ceramics tapes. We would like to optimize through simulations the pre-mixing of the fuel (Hydrogen gas) and oxidizer (Oxygen from Air), and the temperatu...
