The surface convection coefficient between the wire and the air (at temperature Ta) is h. Also determine the heat dissipation rate q. Figure 118.1 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 ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–263 VM118 Analysis Assumptions and Modeling Notes The problem is solved first using conducting area elements (PLANE55) and then using conducting solid elements (SOLID70). Since the problem is axisymmetric, only a one-element sector is needed. A small angle Θ = 10° is used for approximating the circular boundary w...
