Thermal Performances of Roller Shutters

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... En Savoir Plus

Gray Body

A gray body with a spherical cavity with various opening areas is simulated using the _Heat Transfer, Surface-to-Surface Radiation_ interface. The emissivity for each case is computed and compared with the classical gray body theory. The COMSOL Multiphysics® result agrees very ... En Savoir Plus
