Numerical model for two-phase solidification problem in a pipe

A two-dimensional model of heat transfer and solidification of a laminar flow inside a tube has been completed using the commercial fluid dynamics code, Fluent®. The non-equilibrium balance of heat flux on the interface fluid/solid provides the blockage of the pipe. The model is validated with experimental results of blocking lengths. In addition a correlation is obtained to predict the blocking lengths of different fluids and operating conditions such as pipe diameter, mean velocity, wall and liquid temperatures.
