Abstract
The spatial dependence of graybody radiation from a cone, the shape representative of small flames, has been computed. A comparison of the radiative heat flux from this model and experimental measurements of the total heat flux from a flame indicate that up to 74 percent of the total emitted intensity is radiative.
