Unformatted text preview: 251 VM113: Transient Temperature Distribution in an Orthotropic Metal Bar Overview Reference: P. J. Schneider, Conduction Heat Transfer, 2nd Printing, Addison-Wesley Publishing Co., Inc., Reading, MA, 1957, pg. 261, ex. 10-7. Analysis Type(s): Thermal Analysis (ANTYPE = 4) Element Type(s): 2-D Thermal Solid Elements (PLANE55) Input Listing: vm113.dat Test Case A long metal bar of rectangular cross-section is initially at a temperature To and is then suddenly quenched in a large volume of fluid at temperature Tf. The material conductivity is orthotropic, having different X and Y directional properties. If the surface convection coefficient is h, determine the temperature distribution in the slab after 3 seconds in the following locations of the bar: • center • corner edge • face centers of the bar Figure 113.1 Orthotropic Metal Bar Problem Sketch Material Properties kx = 20 Btu/hr-ft-°F ky = 3.6036 Btu/hr-ft-°F γ = 400 lb/ft3 c = 0.009009 Btu/lb-°F h = 240 Btu/hr-ft2-°F Geometric Properties a = 2 in = (2/12) ft b =...
