Unformatted text preview: l cylinder ε = 1 Axial surface of internal cylinder ε = 1 All other surfaces ε = 0 Analysis Assumptions and Modeling Notes The model is reduced to a 2-D axisymmetric case. The material is assumed to be isotropic, the surface is assumed to have uniform emissivity.

VM228: Radiation Between Infinite Coaxial Cylinders Overview Reference: R. Siegel, J. R. Howell, Thermal Radiation Heat Transfer, Hemisphere Publishing, 1992, p. 188. Analysis Type(s): Steady State Radiosity Element Type(s): 2-D 6-Node Triangular Thermal Solid Elements (PLANE35) Input Listing: vm228.dat Test Case Two concentric infinite cylinders are transferring heat to each other through radiation. The problem is modeled as a 2-D pair of concentric circles. The facing surfaces are given surface emissivity values, the non facing surfaces are at...
