Unformatted text preview: c., Reading, MA, 1957, pg. 164, Article 7-8. Analysis Type(s): Thermal Analysis (ANTYPE = 0) Element Type(s): 2-D Thermal Solid Elements (PLANE55) Input Listing: vm99.dat Test Case A rectangular cooling fin with a trapezoidal cross-section dissipates heat from a wall maintained at a temperature Tw. The surrounding air temperature is Ta and the convection coefficient between the fin and the air is h. Determine the temperature distribution within the fin and the heat dissipation rate q. Figure 99.1 Trapezoidal Fin Problem Sketch Material Properties k = 18 Btu/hr-ft-°F h = 500 Btu/hr-ft2-°F Geometric Properties w = 0.96 in = 0.08 ft Loading Tw = 100°F Ta = 0°F Analysis Assumptions and Modeling Notes The finite element model is made the same as the reference's relaxation model for a direct comparison. The solution is based on a fin of unit depth (Z-direction). Only half of the fin is modeled due to symmetry. POST1 is used to extract results from the solution phase. Results Comparison Target...
