RADIATIVE HEAT TRANSFER THROUGH A RANDOMLY PACKED BED OF SPHERES BY THE MONTE CARLO METHOD.

Type of article: Article

Summary

THE RANDOMLY PACKED BED IS ASSUMED TO BE AN ABSORBING-SCATTERING MEDIUM WITH EFFECTIVE ABSORPTION AND SCATTERING COEFFICIENTS. THE PACKING PATTERN IS MODELLED BY A NUMERICAL SIMULATION OF RIGID SPHERES SLOWLY SETTLING INTO A RANDOMLY PACKED ASSEMBLAGE. THE MONTE CARLO SIMULATION GENERATES THE TRANSMISSION CURVE AS A FUNCTION OF BED HEIGHT AND SPHERE EMISSIVITY. RESULTS SHOW A STRONG DEPENDENCE OF THE THERMAL RADIATIVE PROPERTIES ON THE PACKING STRUCTURE AND THE SIZE AND EMISSIVITY OF CONSTITUENT SPHERES.
