Learn about Modeling Vacuum Systems in COMSOL
Until recently, simulation had not been widely used by vacuum system designers because of an absence of commercial simulation tools. Last October, my colleague James Ransley held a webinar about how to model vacuum systems using COMSOL Multiphysics. The webinar was a great success, and it inspired us to produce a dedicated product for modeling vacuum applications: the Molecular Flow Module (new with version 4.3b). This year, on November 21st, James will be giving a webinar explaining the new features […]
Molecular Flow Module: Simulate Rarefied Gas Flows in Vacuum Systems
Vacuum technology has many important applications, from semiconductor device and MEMS fabrication, to vacuum coatings for corrosion protection, optical films, and metallization. The new Molecular Flow Module provides vacuum engineers with previously unavailable tools for modeling gas flows within vacuum systems.
The Graphene Revolution: Part 4
Graphene can be created by way of thermal decomposition at high vacuum. In order to design and optimize these high-vacuum systems engineers might look to simulation, but there are currently not many modeling tools that are up to the task. Let’s have a look at how vacuum systems are relevant to graphene production, why you should simulate them, and how.
What Is Molecular Flow?
Vacuum is naturally associated with the hostile environment of deep space. To achieve such an environment in an artificial setting here on Earth is a very challenging task, and it turns out one cannot even come close to the low pressures of an interstellar vacuum. It is at these low pressures that molecular flow occurs.
