In this paper, a three-dimensional model of HDPE-HIC shielded transport vessel is established. STAR-CCM software is used to numerically simulate the heat transfer characteristics of the shielded transport vessel under normal transport conditions and accident transport conditions, and the temperature distribution of the shielded transport vessel is obtained.
