Unformatted text preview: erline Temperature of a Heat Generating Wire Overview Reference: W. M. Rohsenow, H. Y. Choi, Heat, Mass and Momentum Transfer, 2nd Printing, Prentice-Hall, Inc., Englewood Cliffs, NJ, 1963, pg. 106, ex. 6.5. Analysis Type(s): Thermal Analysis (ANTYPE = 0) Element Type(s): 2-D 6-Node Triangular Thermal Solid Element (PLANE35) 2-D Thermal Surface Effect Element (SURF151) Input Listing: vm58.dat Test Case Determine the centerline temperature and the surface temperature Ts of a bare steel wire generating heat at the rate q . The surface convection coefficient between the wire and the air (at temperature Ta) is h. Also, determine the heat dissipation rate q. Figure 58.1 Heat Generating Wire Problem Sketch Material Properties k = 13 Btu/hr-ft-°F h = 5 Btu/hr-ft2-°F Geometric Properties ro = 0.375 in = 0.03125 ft Loading Ta = 70°F q = 111311.7 Btu/hr-ft3 Analysis Assumptions and Modeling Notes Since the problem is axisymmetric, only a small sector is needed. An angle Θ= 30° is used for m...
