Pressure rise due to freezing of water enclosed in a circular tube has been studied in this paper. A theoretical model is established by considering the heat transfer conditions on the outer surface of the tubes, elastic deformations of the tube walls, and change in the freezing temperature of water due to the increase in pressure. Numerical calculations were performed to integrate the theoretical equations. The calculated results showed a good agreement with the experimental results. The new dimensionless parameters have been introduced, by combining the results thus obtained for various different conditions, to correlate the pressure in tubes to heat transfer conditions on the surface and physical properties and the dimensions of tubes.
