Zooming in on a Compact Camera Module Design with Simulation
Lights, camera, simulation: Read about factors that help define the performance of compact camera modules (CCMs) as well as how optical ray tracing can be used to analyze their design.
Fine-Tuning an HVAC System Design with Simulation
Do you find your office too hot, too cold, or just right? Using simulation, HVAC system engineers can assess indoor climate conditions and ensure maximum comfort among a building’s occupants.
Happy Birthday, John Sealy Townsend
From fluorescent light bulbs and Geiger counters to plasma televisions and semiconductor manufacturing, Townsend discharge has many important applications. Who discovered this phenomenon?
The Quest for Clarity: Tracing Rays in 3 Telescope Designs
The Keck telescope includes a parabolic reflective surface made up of 36 separate interlocking mirrors. Learn more about this and 2 other popular telescope designs via ray tracing simulation.
Modeling Two-Phase Flow in a PEM Electrolyzer
From transportation to industrial applications, hydrogen-based energy storage has shown promise in many fields. Well-designed electrolyzers help make these applications possible.
Building a Solid Foundation for Understanding Seismic Waves
In 1906, there was the California earthquake. In 1908, there was the Lawson Report. In 1910, Harry Fielding Reid proposed the elastic rebound theory. Continue on a deep dive into seismology…
A Quiet Revolution: Analyzing Electric Motor Noise via Simulation
The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.
Happy Birthday, Claude-Louis Navier
When you hear the name Navier, you probably think of fluid flow or the Navier–Stokes equations. But did you know that Claude-Louis Navier worked as a bridge designer and civil engineer?
