Test Case

Flow over a “hill” geometry with separation and reattachment is modeled. Fully developed turbulent profile is specified at the inlet.

Figure 151: Flow Domain

Material Properties	Geometry	Boundary Conditions
Density : 1 kg/m³ Viscosity = 7.5188e-07 kg/m-s	Height of the hill = 20.5 mm	Fully developed profiles are specified at the inlet for (i) Velocity, (ii) Turbulent kinetic Energy, and (iii) Eddy dissipation rate. Average velocity at inlet = 1 m/s
