Unformatted text preview: ons are specified at the pipe inlet and wall. Fluid properties are assumed to be the same for both species, so that computed results can be compared with analytical solution. Figure 209.1 Multiple Species Flow Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–474 VM209 Material Properties Species A ρ = 1 kg/m3 µ = 1.0 x 10-5 Pa-s DBA = 1.43 x 10-5 m2/s Species B ρ = 1 kg/m3 µ = 1.0 x 10-5 Pa-s DBA = 1.43 x 10-5 m2/s Geometric Properties Pipe length = 0.1 m Pipe radius = 0.0025 m Loading Pressure Differential between the pipe inlet and outlet, ∆P = 1.28 Pa Mass fraction of species A at pipe inlet, (YA)in = 0.5 Mass fraction of species B at pipe inlet, (YB)in = 0.5 Mass fraction of species A at pipe wall, (YA)w = 0.9 Mass fraction of species A at pipe wall, (YB)w = 0.1 Analysis Assumptions and Modeling Notes • Steady-state flow • Incompressible flow • Fully developed velocity field • Fluid properties are the same and constant for both species • No source terms • No body forces With the above assumptions, axial momentum equation for the mixture becomes: µ d dVX dρ r = r dr dr dx Applying the boundar...
