As a part of FATE code improvement project, validation of models for heat-transfer and fluid dynamics was carried out. In the 3rd report of this series, heat-transfer and fluid dynamics were extracted as important phenomena for HALW boiling and drying accident. Using a single-region system and a multi-region system, heat-transfer and fluid dynamics were analyzed with existing FATE code.
