T1 = 1000°R
T2 = 460°R Analysis Assumptions and Modeling Notes
The cylinders are assumed to be sufficiently long enough to neglect end losses. A 2-D model is used to determine
the heat transfer rate per unit depth. The thermal conductivity and cross-sectional areas of the conducting bars
are arbitrarily set equal to 1. The Stefan-Boltzmann constant defaults to 0.119 x 10-10 Btu/hr-in2-°R4 (value given
in reference). ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–282 VM125 Results Comparison
