The use of the linear Boltzmann equation is proposed for transport in porous media in a column. By column experiments, we show that the breakthrough curve is reproduced by the linear Boltzmann equation. The advection–diffusion equation is derived from the linear Boltzmann equation in the asymptotic limit of large propagation distance and long time.

多孔介质柱实验中的线性Boltzmann方程

建议使用线性 Boltzmann 方程在柱中的多孔介质中进行传输。通过柱实验，我们表明突破曲线是由线性玻尔兹曼方程再现的。在大传播距离和长时间的渐近极限下，对流-扩散方程由线性玻尔兹曼方程推导出来。
