Analyzing Aircraft Engine Noise Through Simulation
By modeling flow duct systems in aircraft engines, it is possible to optimize the shape of certain engine duct parts and the lining properties in order to reduce the sound emission.
Introducing the Ray Optics Module
COMSOL Multiphysics version 5.0 introduced an add-on module for electromagnetics modeling: the Ray Optics Module. It can be used to perform ray tracing and geometrical optics studies.
Why Haven’t CPU Clock Speeds Increased in the Last Few Years?
Did you ever notice that around the year 2005, the top speed of high-end processors plateaued at 4 GHz? We discuss why this happened and why CPU speeds haven’t increased much since.
Rosetta and Philae: A Historic Landing on a Comet
In 2014, the spacecraft Philae, aboard the Rosetta, landed on a comet for the first time ever. We talk to 2 of the scientists involved in this project about what this means >>
The Tuning Fork Application
Do re mi fa so la ti do! Did you know that the most common standard pitch for a tuning fork is 440 Hz, which forms the note A? See a tuning fork simulation app in action here >>
Hydrocooling Analysis for Fresh Produce Safety
During the hydrocooling process for tomatoes, bacteria can seep through and contaminate the food, making it unsafe to ingest. Researchers from Cornell University used simulation to investigate.
