THE ANALYSIS OF FLOW OF RAREFIED GASES THROUGH PACKED BEDS BY MONTE CARLO METHOD

Abstract

The flow of rarefied gases through sphere packed beds under free molecular region was analyzed statistically by the Monte Carlo method. In analysis, the random packed beds were considered as a collective of regular packed units, and the permeability of this unit was calculated by the Monte Carlo method.
For extension to the packed bed, Oatley''s method was used for the direction of flow and proportional allotment with the ratio of unit area to beds was adopted for the direction of cross section. The calculated results were in good agreement with observed values, suggesting that this analytical method affords easy calculation of conductance of packed beds.
