Schneider, Conduction Heat Transfer, 2nd Printing, Addison-Wesley Publishing Co., Inc., Reading, MA, 1957, pg. 283, article 11-4, eq. (11-21) and pg. 309, article 12-8. Analysis Type(s): Thermal Analysis (ANTYPE = 4) Element Type(s): 2-D Conduction Bar Elements (LINK32) Input Listing: vm115.dat Test Case An infinite plate of thickness , initially at a uniform temperature To, is subjected to a sudden uniformly distributed heat generation rate q and a surface temperature Ts. Determine the temperature distribution in the plate after 12 minutes. Figure 115.1 Heat-Generating Slab Problem Sketch Material Properties k = 20 Btu/hr-ft-°F γ = 500 lb/ft3 c= 0.2 Btu/lb-°F Geometric Properties = 1 ft Loading To = 60°F Ts = 32°F (t>0) q = 4 x 104 Btu/hr-ft3 ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–256 VM115 Analysis Assumptions and Modeling Notes A 1 ft2 area is used for the conduction elements. Due to symmetry only half of the plate is modeled. Automatic time stepping is use...
