Magnetic Transmissions Increase Lifespan of Offshore Wind Farms
Flemming Buus Bendixen, Sintex, Denmark
Sintex is a developer and manufacturer of magnetic couplings, systems that transmit torque and power with significantly increased reliability compared to mechanical transmissions. Because of their noncontact operation and media separation, these couplings are finding crucial roles in cooling offshore wind turbines and chemical pumping applications. Sintex uses simulation apps created in the ...
Multiphysics Modeling in the Biopharma Industry
Pablo Rolandi, Amgen, USA
Amgen, a leading multinational biopharmaceutical company, produces various drug products that have treated serious illnesses in millions of people around the world. Behind every product is a plethora of processes, and a diverse portfolio of simulation tools is needed to ensure drug safety and efficacy. Engineers at Amgen use the COMSOL Multiphysics® software as a platform modeling tool for their ...
Peeling Away Memory Chips
Stefan Behler, Besi, Switzerland
As memory chips become smaller and smaller, designers must ensure that the chips stay intact during the manufacturing process. Besi develops equipment and assembly processes for substrate and wafer packaging production in markets such as consumer electronics, automotive, industrial, and solar energy. Stefan Behler, a senior expert process engineer, used multiphysics simulation to explore and ...
Innovative Motor Designs for Electric Cars Come to Life
Omar Laldin, Faraday Future, USA
If electric vehicles are to ultimately transcend from niche to mainstream, their motor designs must continually progress. Modern improvements in electric vehicle motors, known as power magnetic devices (PMDs), come in the form of simultaneous increases in power capability and manufacturability and decreases in size and cost. Faraday Future, a company that develops intelligent electric vehicles, ...
Analyzing the LHC Magnet Quenches
Lorenzo Bortot, CERN, Switzerland
Engineers and physicists at CERN go to great lengths to ensure that the high-power superconducting magnets that maintain the circular trajectory of particles inside the Large Hadron Collider (LHC) do not revert to a resistive state, an event known as a quench. To understand and prevent quench events, Lorenzo Bortot, an electrical engineer and research fellow at CERN, used numerical simulation to ...
Fuel Cells Poised to Replace India’s Diesel Generators
Ashish Lele, National Chemical Laboratory, India
Inefficient and potentially harmful diesel generators are still the prevailing method of decentralized power generation for telecommunications in urban and rural India. Researchers at the National Chemical Laboratory are investigating proton exchange membrane (PEM) fuel cells, which are strong candidates for this industry because of their cleanliness, compatibility, and efficiency exceeding 30% ...
Simulation Apps Bring STEM to Life
Ivana Milanovic, University of Hartford, USA
While covering the required fundamental material in undergraduate academic programs is the top priority, students require an extra set of knowledge and skills to flourish in the workforce. This is especially true in science, technology, engineering, and mathematics (STEM) fields, where there is rarely an abundance of time for inquiry-based learning and the development of field-specific skills. ...
A New Route to High Sensitivity Pressure Sensors
Jonas Osório, Cristiano Cordeiro, Unicamp; Marcos Franco, Valdir Serrão, Instituto de Estudos Avançados, Brazil
The environments in which sensors are most integral are often the most harsh and unforgiving, such as vacuum chambers, the ocean floor, and petroleum reservoirs. Traditional sensing techniques are not ideal in these applications, whereas optical fiber sensors can provide a versatile pressure sensing solution, as they are sensitive and electromagnetically immune. Researchers at Universidade ...
MTC Develops Simulation App to Revolutionize Design for Additively Manufactured Parts
Borja Lazaro Toralles, Manufacturing Technology Centre, UK
Tolerances and precision in the aerospace industry are astoundingly tight. Because of the high degree of regulation and safety required, errors and deformation from thermal cycling that occur on the micron scale during manufacturing processes can render a part unusable. Manufacturing Technology Centre (MTC), a company that researches and employs additive manufacturing, is working to optimize the ...
Invisible Connections Will Unveil our 5G Future
Eric Gebhard, Bill Rosas, Signal Microwave, USA
The impending evolution of ultrafast 5G networks from concept to reality will entail significant effort into the complex maintenance of impedance and the precision of individual components at high data transfer rates. Connectors, parts that join electrical transmission lines and transfer electromagnetic energy, must remain electrically neutral and have their impedance matched to the transmission ...
