| 中文摘要 | The water duct freezing in a soil of finite depth is performed using finite difference method. The freezing interface is eliminated from consider the Stefan number (St ) is used. The Stefan number is included the effects of both specific and latent heat. The problem is made equivalent to a nonlinear conduction problem with fixed grad for phase change of problem. Both soil freezing and interface condition between soil and duct are included in the analysis. It is found that critical burial depth can be clearly defined when the soil property and earth surface temperature is defined. |
