Test Case
Turbulent flow with gradual separation and reattachment is modeled in an asymmetric 2-D diffuser. The lower wall of the diffuser is divergent with an angle of 10° and expands to about 4.7 times the inlet height.
Material Properties | Geometry | Boundary Conditions |
---|---|---|
Density: 1 kg/m3 Viscosity: 0.0001 kg/m-s |
Inlet height H = 2 M Outlet height = 4.7 H Angle of the divergent section = 10° Length of the straight section after divergence = 21 H |
Fully developed turbulent profile for velocity at inlet with an average velocity = 0.7041 m/s |
