Time Dependent 3D Heat Radiation Calculation
In High Temperature Furnaces
Author(s)
C. Weichmann, R. Backofen & A. Voigt
Abstract
We present fully 3D calculations for time dependent processes in high temperature
furnaces. A mixed finite element approach is used for the coupled simulation of
heat conduction in the massive parts of the furnace and heat radiation between its
surfaces. The view factors are calculated by the hemicube method and the visibility
between surface patches is determined using the z-buffer of the graphics card. The
3D results are compared in an rotational symmetric setting with two-dimensional
simulations.
Keywords: heat radiation, heat conduction, high temperature furnaces, computer
simulation, hemicube algorithm, radiosity, 3D, time dependence.
