Abstrakt

Laminar flow heat transfer in a tube with internal solidification is investigated theoretically and experimentally. Assuming a uniformly tapered flow passage contracted with the solidified layer, the numerical analysis determines the heat transfer rate, fluid velocity and solid-liquid interface profile as a function of time and position along the tube. Experiments are performed for water flowing inside a tube in vertical position. The heat transfer data for B =0−2.0, where B measures the relative cooling rate, agree well with the theory; however, the data for B > 2.0 are much above the theoretical values due to turbulent heat transfer augmented by a wavy profile of the solid-liquid interface downstream of the expanded flow section near the exit of the tube.
