Analysis of heat transfer in a lightscattering material exposed to a finite source of collimated radiation
Abstract
The problem of the effect of a beam of finite dimensions on heat transfer in a lightscattering isotropic material is investigated without a detailed analysis of effects associated with radiation propagation in a scattering medium. A simple radiation propagation model is employed, and the problem is solved numerically using a stable implicit finite difference scheme. The algorithm for calculating temperature field proposed here is verified through a comparison with results of an approximate analytical solution. The effect of beam dimensions and energy density on heat transfer is evaluated.
