摘要
本文对冬季条件下渠道基础冻结过程的非线性、非稳定水热耦合问题进行了数值模拟。
This paper deals with the two dimensional phase change temperature moisture coupling field in the base of irrigation ditch in the seasonal frozen zones under severe climate conditions.On the basis of Harlan model and Darcy principle,totally implicit difference scheme in numerical analysis is adopted by considering the moisture and temperature coupling equation.
