Body-to-Body Radiation
The transfer of heat between objects without physical interaction can be simulated in a heat transfer analysis by using the body-to-body radiation capability. Body-to-body radiation occurs when a body emits heat, typically in all directions, and a portion of the radiated heat falls on another body, which absorbs or reflects the energy, thereby changing temperature. This capability enables engineers to analyze the temperature distribution for multi-body radiation scenarios where a large temperature gradient occurs (e.g., furnace applications, a cryogenic system) or for heat transfer in a vacuum (e.g., thermos bottle, light bulb, spacecraft components, weather balloon payload components). FEMPRO, ALGOR's finite element modeling, results evaluation and presentation interface, includes options that enable the user to conveniently specify body-to-body radiation settings such as emissivity curves, surfaces, enclosures and view factor parameters. An automatic view factor calculator controls the extent to which the different bodies interact. Body-to-body radiation can be simulated for steady-state and transient heat transfer analysis, combined steady fluid flow and heat transfer analysis and transparent bodies. For more information on our body-to-body radiation capabilities, see the ALGOR User's Guide.
