An analysis of temperature radiation interchange problems
Besides conduction and convection, heat transfer is dominated in the present problem and the temperature range of T > 500° C by thermal radiation. Temperature radiation interchange is described by Lambert's Cosine law. This leads to a Fredholm integral equation of the second kind, which is s...

by thermal radiation. Temperature radiation interchange is described by Lambert's Cosine law. This leads to a Fredholm integral equation of the second kind, which is solved numerically by a Galerkin Finite Element model. The efficiency of this approximation is verified on a simple example, the radiation interchange of two parallel plates where a semi-analytical solution exists. A complete instationary heat flow analysis with radiative transfer is performed within two further examples, the thermal calculation of a radiation cooled MPD arc thruster, as well as the thermal layout of a motor car headlight. |
