论文摘要
我们将熔点的操作分析为探针周围液体/实心界面的Stefan问题。我们假设液体层很薄，因此可以通过润滑理论进行分析。由此产生的Stefan问题可在封闭形式中解决。该解决方案确定探针和周围冰之间温度差的依赖性，探针的大小，形状和重量，液态水的粘度以及固体冰的热性能。
We analyze the operation of melting probes as a Stefan problem for the liquid/solid interface surrounding the probe. We assume that the liquid layer is thin and, therefore, amenable to analysis by lubrication theory. The resulting Stefan problem is solvable in closed form. The solution determines the dependence of the penetration speed on the temperature differential between the probe and the surrounding ice, the size, shape and weight of the probe, the viscosity of liquid water and the thermal properties of solid ice.
