Unformatted text preview: phere Publishing Corporation, 1981, pg. 229, problem 21. Analysis Type(s): Transient Analysis (ANTYPE = 4) Element Type(s): 3-D Thermal Solid Elements (SOLID70) 3-D Thermal Surface Effect Elements (SURF152) Input Listing: vm192.dat Test Case A carbon steel billet is initially at a temperature TB and is supported in such a manner that it loses heat by radiation from all its surfaces to surroundings at temperature TE. Determine the temperature TB of the billet at the end of 3.7 hours. Figure 192.1 Cooling of a Billet by Radiation Problem Sketch Material Properties Geometric Properties C = 0.11 Btu/lb-°R a = 2 ft 3 b = 4 ft ρ = 487.5 lb/ft ε = emissivity = 1.0 Stefan-Boltzmann constant = 0.1712x10-8 Btu/hr-ft2-R4 Loading TE = 70°F (530°R) TB = 2000°R (at t = 0) ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–436 VM192 Analysis of Assumptions and Modeling Notes The billet is modeled using a single SOLID70 element overlaid with a SURF152 element on each of its faces. The surface elements have a comm...
