Abstract
A lattice Boltzmann model for unfrozen water infiltration in saturated soil undergoing progressive freezing is proposed: (1) a stochastic growth method for particle generation is used to generate the structure of the soil particles, (2) a geometric method is used to calculate the temperature distribution at phase change, (3) the multiple relaxation time lattice Boltzmann method is selected for the solution of fluid flow through the frozen soil. The contents of unfrozen water and the hydraulic conductivities for two types of soil, sand and silt loam, obtained by the model were compared with experimental results. The correlation coefficients between the estimated and the experimental values were 0.97 and 0.96, respectively, for the contents of these two types of frozen soil in unfrozen water, and were 0.96 and 0.95, respectively, for their hydraulic conductivities.
