Net Radiative Heat Exchange

How to use this tool

1. Calculate ideal radiative heat transfer between a surface and a large surrounding enclosure.
2. Set surface area, emissivity, surface temperature, surrounding temperature in the indicated units.
3. Calculate and compare net outward radiative power.

Try this example

{
  "area": 1,
  "emissivity": 0.9,
  "surface": 400,
  "ambient": 300
}

Accuracy and scope

Large isothermal surroundings and a gray surface with unit view factor; convection and conduction excluded.
