The analysis of heat and water fluxes in frozen silty soil
作者：DaHu Rui,Ming Lu,Kunio Watanabe,Jun Zhang
摘要：In this paper,based on the basic equations of water flow and heat transfer,the hydrothermal coupling model is established.The numerical model was realized in COMSOL Multiphysics software,and simulation results are compared with the experimental results of Watanabe and Wake(2008)to verify the effectiveness of the model.Through the calculation,we can obtain the dynamic changes of heat and water fluxes,thermal and hydrological properties,matric potential and temperature gradient in unsaturated freezing soil;and these variables are unmeasurable in practice.
