Heat Conduction Analysis Examples Using a Realistic Model¶
Analysis Models¶
For heat conduction analysis, a spent nuclear fuel transport cask is used as a realistic model. Three verification examples with different mesh resolutions are defined for this realistic model. These examples are listed in Table 9.5.1. The model geometries are also shown in Figures 9.5.1 through 9.5.4.
