快速冷冻成型（Rapid Freeze Prototyping，RFP）是通过逐层沉积和冻结水来制造冰件的一种方法。推导了冰层凝固过程中冰壁温度的解析解，可用于估算凝固时间。本文还研究了冰层凝固后冰墙的自然冷却。冰墙的加热和冷却的解析解与数值计算和实验结果吻合良好。
Rapid Freeze Prototyping (RFP) builds ice parts by depositing and freezing water in a layer-by-layer manner This paper presents a one-dimensional transient heat transfer model for a thin ice wall built by the RFP process. Closed-form solutions for temperatures of the ice wall during solidification of a layer of water are derived, which can be used to estimate the solidification time. Natural cooling of the ice wall after solidification of a water layer is also studied. The analytical solutions of heating and cooling of the ice wall agree well with both numerical and experimental results.
