Unformatted text preview: r from a black body of unit area A at a temperature T, when ambient temperature is Ta. Figure 106.1 Radiant Energy Emission Problem Sketch Material Properties ε = emissivity = 1.0 Geometric Properties A = 1 ft2 F = form factor = 1.0 Loading T = 3000°F Ta = 0°F Analysis Assumptions and Modeling Notes A conversion factor of 144 in2/ft2 is included in the area input to convert the default Stefan-Boltzmann constant to feet units. The temperature offset of 460°F is required to convert the input Fahrenheit temperature to an absolute (Rankine) temperature. The node locations are arbitrarily selected as coincident.
