文摘
- •
Use of constant heat transfer coefficient for fracture analysis is not sound.
- •
On-time heat transfer coefficient should be used for thermal fracture prediction.
- •
∼90% of the actual fracture stresses were predicted with the on-time transient h.
- •
Thermal-hydraulic codes can be used to better predict brittle cladding fracture.
- •
Effects of surface oxides on thermal shock fracture should be accounted by h.
