Unformatted text preview: m121.dat Test Case Pressure-driven flow in a straight duct of circular cross-section with radius R. Inlet and outlet boundaries have uniform, dissimilar pressure boundary conditions. The mean fluid temperature at the inlet is Tm,i. The pipe is subjected to a uniform wall heat flux, q'', throughout its length, L. From the Velocity Field Determine VXc = centerline axial velocity VXm = mean axial velocity Re = Reynolds number = mass flow rate From the Temperature Field Determine LE,T = thermal entry length Tm,o = outlet mean temperature Tw,o = outlet wall temperature Tc,o = outlet centerline temperature τw = wall shear stress Fluid Properties Mercury (Hg) at 300K ρ = 13,529 kg/m3 µ = 1.523 x 10-3 kg/m-sec k = 8.54 W/m-K Cp = 139.3 J/kg-K Pr = 0.025 (liquid metal) Geometric Properties R = 2.5 mm L = 0.1 m Loading ∆P = 1.0 Pa Tm,i = 300 K q''= 5000 W/m2 Figure 121.1 Pipe with Uniform Heat Flux Problem Sketch ANSYS Verification Manual .
