TLDR
Radiant emission from diffuse conical cavity openings, including wall distribution of radiant emittance, heat flux, and temperature, was studied in this paper, where the authors presented a method to detect the presence of radiant emissions from conical cavities.Abstract:

Application of Monte Carlo to Heat Transfer Problems
TL;DR: This chapter presents a view of the problems that have been solved by Monte Carlo in certain areas of heat transfer, and the techniques used in their solution, using only the straightforward Monte Carlo approach.

Emissivities of diffuse cavities: Isothermal and nonisothermal cones and cylinders
R. E. Bedford,C. K. Ma +1 more
TL;DR: In this paper, local, hemispherical, effective emissivities and integrated cavity emissivity have been computed for isothermal and nonisothermal diffuse conical and cylindrical cavities having lids with circular apertures.

Two blackbody radiometers of high accuracy.
J. M. Kendall,C. M. Berdahl +1 more
TL;DR: Two cavity-type radiometers have been developed, based on first principles, having the capability of measuring an irradiance with an indicated error 0.3%, which indicates the degree of confidence that can be expected in measurements made with blackbody cavity radiometers.

Radiation heat transfer at a surface having both specular and diffuse reflectance components
Ephraim M Sparrow,S. L. Lin +1 more
TL;DR: In this paper, a method of analysis has been devised for determining the radiant interchange among surfaces, each of which may have both specular and diffuse reflectance components, and specific analytical and numerical consideration is given to radiant interchange in cylindrical and conical cavities and to radiant transport through a circular tube.

Kirchhoff’s Law of Thermal Emission: 150 Years
TL;DR: In this paper, the authors revisited Kirchhoff's law to mark its 150th anniversary and highlighted serious overreaching in its formulation, including the notion that cavity radiation must always be black, or normal: depending only on the temperature and the frequency of observation.
