摘要
Abstract
In order to simplify the numerical simulation for gas permeation in a hollow masswe compared the physical mechanism of gas motion in porous medium with that in voidsand discussed the possibility of using general permeation model for porous medium to simulate the fluid permeation in porous medium containing voids by regarding the void as the porous medium.The method for evaluating the equivalent permeability of void is proposed and veri-fied.It is shown that when the porosity of the void is 1and the equivalent permeability of the void is no less than the permeability divided by the porosity of the porous mediumthe simulation results from the simplified modelwhich takes the area containing voids as the one with porous mediumare approximately the same as those from the general model for porous medium.关键词
