在许多应用中，有一种情况是将物质冻结在冷却剂输送管外。由于冷却剂从冷冻物质中吸收热量时，其温度会向轴向升高，因此冻结层虽然是轴对称的，但其厚度会向轴向变化。相当多的论文讨论了这个问题[1 -6]。有些人做了限制性的假设，所有这些都涉及数值计算来获得解。其中，斯派洛和许b[6]的论文分析最为透彻。然而，这与其他早期论文的结果没有可比性。
A SITUAWIN~ O~~ O~ to many applicationsis the freezing ofa substance outside a coolant carrying tube. Owing to the axial increase in the temperature of the coolant as it picks up heat from the freezing substance, the frozen layer, while being axisymmetric, varies in thickness axially. Quite a few papers have addressed this problem [l-6]. Some made restrictive assumptions, and all involved numerical calculations to obtain the solution. Among these, the most thorough analysis is made in the paper by Sparrow and Hsu [6]. However, this presented no comparison with the results of the other, earlier, papers.
