Modeling Radiation in Semitransparent Media with COMSOL®
Durée: 58:46
Radiation must be accounted for in various applications, like glass at high temperatures, in-depth absorption of lasers, and gas in combustion chambers. Watch this archived webinar to learn how to model radiation in semitransparent media in COMSOL Multiphysics®, as well as the different approaches for doing so, including the Rosseland approximation, P1 approximation, discrete ordinates method, and Beer–Lambert law.
