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.
This model example illustrates applications of this type that would nominally be built using the following products:Heat Transfer Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
