The main aim of this project is to develop a mathematical model to simulate coupled heat and water flow through layered soils. The coupling of the two processes will allow us to examine the interaction between heat and water flow. The project also aims to extend the heat component of the flow model to granulated heterogeneous soils by developing a model that encapsulates heat effects at the microscopic and macroscopic level. The model will be applied to two problems 1) hydraulic barriers in cover liner designs for landfills and 2) assessing the ability of heat sensors to measure various soil properties under field conditions.

该项目的主要目的是开发一个数学模型来模拟通过层状土壤的耦合热和水流动。这两个过程的耦合将使我们能够研究热量和水流之间的相互作用。该项目还旨在通过开发一个包含微观和宏观层面热效应的模型，将流动模型的热分量扩展到颗粒状异质土壤。 该模型将被应用于两个问题1）填埋场的覆盖衬垫设计中的水力屏障和2）评估热传感器在现场条件下测量各种土壤特性的能力。
