A new model is presented for treating transient freezing in laminar tube‐flow. The liquid motion is constrained by requiring head‐loss versus flow‐rate to match that of a linear pump‐characteristic curve. This feature enables the model to describe freezing conditions which may lead to occlusion of the tube with solid‐phase material. The results demonstrate the sensitivity of tube occlusion both to temperature and liquid‐pumping capability. Both steady‐state and transient results obtained compare favorably with those found in the literature, which include an exact steady‐state solution. Maximum error is estimated at 15%.
