Free Convection in a Light Bulb

Application ID: 303


This model treats the free convection of argon gas within a light bulb. It shows the coupling of heat transport (conduction, radiation and convection) to momentum transport (non-isothermal flow) induced by density variations caused by temperature.

COMSOL Multiphysics model makes it possible to determine the temperature distribution on the outer surface of the bulb, as well as the temperature and pressure distributions within the bulb.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
