Abstract

Exchange factor analysis has been shown to be an alternative to zonal analysis in enclosures with participating media. An experimental measurement of exchange factors for a cubic enclosure has been done, and practical problems associated with the measurements are discussed. The effects of isotropic scattering and absorption-isotropic re-emission processes are known to be the same for their contribution to energy exchange paths in systems with equal optical thickness. The measurement of these exchange factors is achieved by using an enclosure containing a near-isotropically scattering medium. The heat transfer results for the pure radiation case are demonstrated by using these experimentally determined exchange factors in the analysis, and are compared with the analytical results.
