Unformatted text preview: Heat Transfer, 2nd Printing, Addison-Wesley Publishing Co., Inc., Reading, MA, 1957, pg. 193, article 8-8 Analysis Type(s): Thermal Analysis (ANTYPE = 0) Element Type(s): 2-D Thermal Solid Elements (PLANE55) Input Listing: vm105.dat Test Case A long hollow generator coil has its inner and outer surface temperatures maintained at temperature To while generating Joule heat at a uniform rate q . The thermal conductivity of the coil material varies with temperature according to the function k(T) = C0 + C1 T. Determine the temperature distribution in the coil. Figure 105.1 Heat Generating Coil Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–238 VM105 Material Properties C0 = 10 Btu/hr-ft-°F Geometric Properties ri = 1/4 in = 1/48 ft ro = 1 in = 1/12 ft C1 = 0.075 Btu/hr-ft-°F2 Loading To = 0°F q = 1 x 106 Btu/hr-ft3 Analysis Assumptions and Modeling Notes Since the problem is axisymmetric only a symmetry sector (one-element wide) is needed. A small angle (Θ=10°) is used fo...
