Unformatted text preview: inders Problem Sketch Material Properties ε1 = 0.7 ε2 = 0.5 Geometric Properties r1 = 1 in r2 = 2 in Loading 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 .
