Optimizing Passenger Vehicle Design with Simulation Apps - new
Sitarameswara Sarma Akella, Mahindra, India
The fast-paced passenger vehicle design process at Mahindra, a multinational automotive manufacturer, demands efficient collaboration between manufacturing teams, design engineers, and computer-aided engineering (CAE) analysts. Validation of design changes to stabilizer bars, critical components in car suspension, and chassis involves time-consuming iterations back-and-forth between teams. To ...
Communicating from Space: The Front End of Multiscale Modeling
Jiyoun Munn, Technical Product Manager, RF Module, COMSOL
As satellites and astronauts travel further out in space, the more communication challenges they are faced with. This article discusses the variety of antennas that can be found on a spacecraft and the different simulation techniques that are best suited for each type of antenna such as helical antenna, horn antenna, dish reflector antenna, and phased array antenna.
Multiphase Flow Simulation Guides Wastewater Treatment Plant Design
Ronnie Berg, Tauw; Tony Flameling, Eindhoven Water Board, Netherlands
To improve the health of the Dommel river, an aeration unit has been added to the Eindhoven wastewater treatment plant to increase the oxygen level of the effluent before merging with the river. Before construction, a CFD model of a multiphase turbulent fluid flow was created to determine the best arrangement of aeration units and heights of sections of the adjustable dam for various river water ...
Simulation Apps Advance Tribology Research
Thomas Lohner, Gear Research Centre, Technical University of Munich, Germany
Modeling thermal elastohydrodynamically lubricated (TEHL) gear contacts quickly reveals a complex system of interconnected heat, mechanical, and fluid phenomena. Engineers at the Gear Research Centre, Technical University of Munich, enlisted multiphysics simulation to create a mathematical model that would allow them to find ways to improve the power density, efficiency, and noise-vibration ...
The Sound of Perfection Thanks to the Modeling of Acoustic Metasurfaces
Hervé Lissek, École Polytechnique Fédérale de Lausanne, Switzerland
At the École Polytechnique Fédérale de Lausanne (EPFL), engineers have designed an acoustic metasurface that could be used to enhance the acoustics of concert halls, soundproof homes, and reduce the noise of an engine during a flight. The many complex phenomena that must be considered in modeling a metasurface make the decision to use multiphysics simulation an easy choice. With simulation, the ...
ASML Advances Computing Breakthroughs with Multiphysics Modeling
Fred Huizinga, ASML, Netherlands
At ASML, the development of cutting-edge computer chips and the machinery to produce them requires a complex understanding of the many coupled physical processes involved. To design machines at this level of precision requires simulation at every step, making the availability of a comprehensive simulation toolbox invaluable. For example, engineers at ASML worked on the design of an air bearing ...
Lightweighting with Aluminum: Corrosion Apps Guide Leading Design
Danick Gallant, NRC, Canada
To achieve fuel efficiency goals, conventional materials for car structures, such as structural steel, must be combined with lighter materials, such as aluminum. Scientists at the National Research Council Canada (NRC) develop corrosion-resistant multimaterial assemblies containing both aluminums and steels as well as optimize the cost-effective processes for their mass production. NRC employed ...
Going with the Flow to Optimize Fluid Sensors
Vivek Kumar, Endress+Hauser, Switzerland
Endress+Hauser specializes in instrumentation development and produces a variety of measurement devices and sensors. One of their specialties is flow meters, devices that monitor and sense the characteristics and properties of fluids. The accuracy of these sensors must be consistently maintained and improved, and multiphysics simulation is a primary tool in doing so. Using multiphysics ...
