Test Case
Flow past an axisymmetric afterbody, representing the hull of ship. The flow separates on the rear face of the body.
| Material Properties | Geometry | Boundary Conditions |
|---|---|---|
|
Density: 1 kg/m3 Viscosity: 1 X 10–6 kg/m-s |
Length of the afterbody = 1.0 m Maximum radius of the afterbody = 0.04556 m |
Fully developed turbulent velocity profile on the inlet normal to axis Axial velocity = 5.9 m/s on the inlet parallel to axis |
Analysis Assumptions and Modeling Notes
The far-field boundary of the domain is set parallel to the axis and is modeled as velocity inlet. Fully developed profile is specified at the transverse velocity inlet.
