Monte Carlo solutions for radiative heat transfer in irregular two-dimensional geometries

Several new methods of computing radiation heat transfer have emerged in recent Years, and thorough testing is often required to validate these. Monte Carlo methods can provide exact solutions within statistical limits, hence are attractive for validation purposes. Unfortunately, many Monte Carlo solutions currently available in the literature are not useful for testing new solution techniques for complex geometries, because they either treat simple cases or application-specific irregular geometries. The intent of this paper is to provide solutions of general interest for two-dimensional irregular geometries using the Monte Carlo method. The paper presents radiative heat flux solutions for three enclosures with absorbing, emitting, and anisotropically scattering medium. 8 refs., 6 figs
