Heat dissipation through radiation in aircraft design involves the transfer of heat from hot components to their surroundings in the form of electromagnetic waves (infrared radiation). While there isn’t a specific formula for heat dissipation through radiation, it is governed by the Stefan-Boltzmann Law, and I can provide a definition and explanation of this process along with the SI units involved.
- Q is the rate of heat transfer through radiation (in watts, W).
- ε is the emissivity of the radiating surface (dimensionless).
- σ is the Stefan-Boltzmann constant (in W/(m²·K⁴)).
- A is the surface area through which heat is radiated (in square meters, m²).
- T₁ is the absolute temperature of the radiating surface (in kelvin, K).
- T₂ is the absolute temperature of the surroundings (in kelvin, K).
