ENT333 Radiation Heat Transfer
Across
- 1. Rate at which radiation leaves a surface due to emission and reflection in all directions per unit area of the surface
- 4. Fraction of the incident radiation reflected by matter.
- 7. Direction dependent
- 9. Referring to a single-wavelength (monochromatic) component.
- 10. Fraction of the incident radiation absorbed by matter.
- 11. Electromagnetic energy emitted by matter at a non-zero temperature
- 12. Rate of radiant energy propagation in a particular direction
- 13. walls constructed out of low emissivity, high reflectivity materials to reduce the net radiation between two surfaces
Down
- 2. Independent of direction
- 3. Rate at which radiation is incident on a surface from all directions per unit area of the surface
- 5. Fraction of the incident radiation transmitted by matter.
- 6. Ratio of the radiation emitted by a surface to the radiation emitted by a blackbody at the same temperature.
- 8. The ideal emitter and absorber.
