Abstract

In the past, a lot of studies in terms of phase change phenomenon of water in a rectangular cavity, a circular tube, and around a circular tube have been carried out by experiments and numerical calculations. The present study proposes a numerical calculation method based on both finite volume and temperature recovery methods for the solution of freezing and melting behavior of water. In this paper, the numerical result computed by the numerical calculation method has been compared with experimental results by other researchers in order to verify the validity of the numerical calculation method. As a result, numerical calculation results for both the shape of ice formation and streamlines in unfrozen water were in good agreement with the experimental ones previously obtained by other researchers.
