“…They drew out a correlation to predict the blocking lengths of different fluids and operating conditions. They validated their numerical modeling with Cheung and Baker [5] experimental results of blocking lengths. Also, Lu and Wang [6] completed a numerical analysis of the heat transfer associated with freezing phase change for a pipeline filled with crude oil in soil saturated with water during pipeline shutdown in winter when the exterior temperature is below the freezing point of water.…”

A numerical solution to a two-dimensional model of flow and transient heat transfer involving solidification in a pipe has been established. Where the temperature of pipe wall is below the freezing point of fluid, phase change of flowing fluid and the influence of different boundary condition, such as pipe wall temperature, initial temperature and inlet velocity has been taken into account. Also it has been investigated to elicit proper non-dimensional numbers to show the solidification proceeding results. Additionally comparing the two acceptable inlet conditions, show distinctions between velocity inlet and pressure inlet boundary condition in such problems, which affect the whole freezing process.

“…2 shows the comparison between the blocking length of numerical results from our model and experimental results from Ref. [10]. These are obtained using water on different operating conditions such as mean velocity of 0.6, 0.95 and 1.4 m/s; pipe diameters of 4.7 and 7.3 mm and wall temperature of 77 and 195 K. Also an olive oil has been simulated.…”

“…With reference to the olive oil, the errors are important, up to 40%. The authors consider that there is an important uncertainty with reference to the properties of the olive oil, which are not specified on the Cheung and Baker's work [10] and can suffer important variations from some sources to others. As it was expected, a larger blocking length, Z, is provided by a higher value of: the initial temperature of the liquid phase, T 0 ; the mean velocity flow, V ; the diameter of the pipe, D and the wall temperature, T W .…”

“…Considering the simplicity of the current approach and the possible experimental errors, the results are deemed satisfactory. The second case used to validate the model is the experimental study of Cheung and Baker regarding the transient water freezing in pipe flow [6]. A picture of the experimental setup, taken from the mentioned study, is shown in Fig.…”

Abstract. Even though molten salts have many useful characteristic, especially as coolants for nuclear reactors, they are prone to freezing due to their high melting point. The solidification of the salt inside the piping system could cause structural damage and stop the flow of coolant with possible serious problems. Modelling the freezing process is therefore of primary importance for nuclear safety. In this study a quasi-steady thermo-hydraulic model has been derived and implemented to describe the transient freezing of molten salts. The partial differential equations describing the solidification/melting of the salt are solved numerically using a combination of standard explicit and implicit methods. Validation of the model is presented based on previous experimental studies for two separate cases.
