KEYNOTE TALKS AT THE
COMSOL CONFERENCE 2020 NORTH AMERICA
Want to see firsthand how industry experts are using multiphysics modeling to innovate? Join us for the virtual keynote talks during the COMSOL Conference 2020 North America. After each talk, you have the opportunity to ask questions to the speakers about their presentations. The online Keynote session also features a sneak preview of the latest version of COMSOL Multiphysics®.
In this presentation, Svante Littmarck, CEO of the COMSOL Group, will introduce COMSOL Multiphysics® version 5.6.
About the Speaker
Svante Littmarck is the president and CEO of COMSOL, Inc. He cofounded the COMSOL Group in 1986. In 2004, Littmarck received an honorary doctoral degree from the Royal Institute of Technology (KTH) in Stockholm, Sweden, for the development and international reach of high-quality software for scientific computations through his company COMSOL.
Food Equipment Development Using Multiphysics Simulation
Recent advances in solid-state RF technology have led to exciting new applications in the food equipment industry. Solid-state generators allow for closed-loop heating, where feedback from the food-cavity system can be used to respond to thermophysical changes during cooking. Utilizing the RF and Heat Transfer modules with COMSOL Multiphysics®, LiveLink™ for MATLAB®, and COMSOL Compiler™ enables ITW Food Equipment Group engineers and chefs alike to explore how microwaves interact with food while optimizing their individual workflows.About the Speaker
Christopher Hopper is a senior RF engineer for the IBEX group at Illinois Tool Works. He received his PhD in physics, specializing in superconducting RF structures for particle accelerators. He has extensive experience with simulation tools and numerical computation software. His primary responsibilities include modeling and training RF systems, hardware/software testing and validation, and algorithm development.
Utilizing COMSOL® for Rapid Prototyping
COMSOL® can be utilized for rapid design cycle phases using modeling in conjunction with prototype test data. The design and modeling process, along with the benefits of this approach, are demonstrated for use in acoustic design for sonar systems. The rapid design cycle approach has been proven to be beneficial in determining unknown material properties and has even been used to determine manufacturing defects in production. Made possible by the rapid design cycle method, a review of the Northrop Grumman’s µSAS™ SONAR system will also be discussed.About the Speaker
Lauren Lagua is an acoustics engineer for Northrop Grumman Corporation (NGC) in their Undersea Systems Division. She received her MS from the University of Maryland, Department of Mechanical Engineering, with a focus on nonlinear, viscoelastic material analysis. At NGC, her role focuses on sonar transducer design, manufacturing, and acoustic testing.
Diagnosing Process Problems Using Multiphysics and Multiscale Simulation
Simulation is often used in Saint-Gobain to diagnose problems we are having with products or processes. Compared to other FEA or CFD software, COMSOL Multiphysics® is helpful for problems that are multiphysics and multiscale. For example, you can include heat diffusion, mass diffusion, chemical reaction, and flow equations, and, with regards to multiscale, there is the flexibility to model in 1D, 2D, 3D, and with extra dimensions. A generalized example related to reactions in porous media in industrial reactors will be shown in this talk. The example can be related to drying, sintering, debinding, purifying, vapor deposition, and similar processes.About the Speaker
David E. Woolley, PhD, PE, is a senior principal scientist at Saint-Gobain. He is a graduate of MIT (SB math, SB materials science & engineering, PhD materials engineering). He is a professional engineer (mechanical engineering) in Pennsylvania. He joined Saint-Gobain in 2000. He has done testing and modeling for several topics of interest to Saint-Gobain, generally in the areas of ceramics, plastics, abrasives, and building materials. Some example projects include the following: diesel particulate filter (DPF), crystal growth (sapphire), solid oxide fuel cell stacks, electrochromic windows, ceramic catalyst supports, fused cast refractories, ceramic sintering, nickel electroplating, fixed diamond wire, polymer extrusion, polymer mixing, and drying.
Modeling Flow of Exhaled Droplets between Two Runners
Modeling particulate flow in air is important for the mitigation of airborne pathogen transmission. I will highlight models developed at Veryst Engineering for this application using COMSOL Multiphysics®. I will focus on an example involving two runners in an open space running six feet apart and droplets emanating from the mouth of the front runner. I will show the predicted airflow around the runners and motion of the droplets and their interaction with the second runner. The particle tracing simulations account for variations in particle size, gravity, drag force, turbulent dispersion, and particle evaporation.About the Speaker
