摘要: 为了研究多孔介质对气体和气溶胶的封闭能力,用数值方法模拟了气体和气溶胶在多孔介质中的迁移.考虑了渗透、吸附过滤、扩散、热传导等因素,在柱对称坐标下用双孔双渗模型进行了数值模拟,并与实验结果进行了比较.计算结果显示,多孔介质对气溶胶有较强的阻挡作用,模拟实验结果也证明了这一点.

Abstract: In order to evaluate the migration of aerosols in porous media driven by gases, a dual porosity dual permeability mathematical model is proposed in symmetric cylinder coordinates.The processes of permeation, absorption, diffusion and heat exchange are considered. Calculated results show that aerosols could be contained in porous media well. Simulating experiments confirmed the prediction.

Key words: aerosol, porous media, migration, numerical simulation, dual porosity
