Abstract
The transient heat transfer problem of solidification of a liquid flowing in a buried pipe is analyzed. The system is cooled from a horizontal flat top surface. The model described in the preceding two manuscripts in this series has been extended to the case when a fluid in laminar flow inside a buried pipe freezes. The cross section for flow, which changes with axial position and time, has been approximated as an ellipse. The velocity profile, which is required in the partial differential equation for the temperature inside the flowing fluid, is determined from the dimensions of the ellipse. Numerical procedures are presented for tracking the moving interface between the solid and the fluid in laminar flow. Simulation examples demonstrate the impact of the Reynolds number on the times to freezing, the temperature profiles and the thickness of the ice layers formed. The effects of pipe burial depth and of other parameters in the model are also examined.
