Abstract

The emissivity c of cylindrical cavities with different bases (flat, perpendicular to the axis; flat, inclined to the axis; conical) is derived from measurements of the cavity reflectance ρc. A general formula for the calclation of ρc = 1 − c is given, which holds for high values of the ratio length L of the cylinder to radius R of the cylinder. For a flat base perpendicular to the axis only the value of the reflectance ρ0 of the wall material is needed; in both other cases one must refer to the measurements.
