文摘
- •
Temperature and stress distribution on a radiant heating tube are examined numerically.
- •
The numerical model is validated with experimental results.
- •
The stress calculations conducted are based on elastic material parameters.
- •
Critical areas of the component can be identified also with elastic material parameters.
- •
Mainly responsible for the stresses occurring are temperature differences on the tube.
