.... The zonal method is used to establish the governing radiation transfer model. Direct exchange areas are calculated by the flux planes approximation. The thin layer approximation (TLA) is then introduced for increasing CPU efficiency. Three different numerical integration schemes made possible by the TLA...

...Yu Yan Jiang Exchange-area-based methods (EAMs), such as the zonal method, the combined Monte-Carlo and zonal method, etc., are widely used in the numerical computation of thermal radiative transfer. In view of their inefficiency in treating with the anisotropy of radiation, researchers have been...

.... The thermal and momentum transport in both glass layers and gas are coupled at the interface boundaries. The neck-down profile is generated using an iterative numerical scheme. The zonal method is applied to model the radiation transfer in the glass preform. The gas is taken as nonparticipating. Coordinate...

... on radiative transport. The zonal method is applied to calculate the radiative heat transfer within the neck-down region of the preform. The radiative heat transfer between the preform and the furnace is computed by an enclosure analysis. A parallel computational scheme for determining the direct exchange...
