Analysis Type(s): Thermal Analysis (ANTYPE = 0) Element Type(s): 3-D 20-Node Thermal Solid Elements (SOLID90) Input Listing: vm162.dat Test Case A circular cooling fin of rectangular profile is attached to a cylindrical surface having a temperature T1. Determine the temperature T2 at the tip of the fin if the fin is surrounded by cooling air at temperature To having a convective film coefficient h. Figure 162.1 Circular Fin Problem Sketch Material Properties h = 100 Btu/hr-ft2-°F k = 15 Btu/hr-ft-°F Geometric Properties r1 = 0.5 in = 0.04167 ft r2 = 0.75 in = 0.0625 ft t = 0.0625 in = 0.005208 ft Loading T1 = 100°F To = 0°F Analysis Assumptions and Modeling Notes An arbitrary 5° sector is used to model the axisymmetric fin.
