Frozen Rotor with Initialization
The Frozen Rotor with Initialization study is used for simulations of turbulent fluid flow in rotating machinery. It generally consists of two study steps: a Wall Distance Initialization study step, solving for the distance function to the closest wall, followed by a Frozen Rotor study step solving for velocity, pressure, turbulence, and other fields. Additionally, when the Mixing Plane feature is active for The High Mach Number Flow Interfaces in 3D geometries, a Mixing Plane Initialization study step is added before the Frozen Rotor study step. In the Frozen Rotor study step, the rotating parts are kept frozen in position, and the rotation is accounted for by the inclusion of centrifugal and Coriolis forces.
The study is especially suited for flow in rotating machinery where the topology of the geometry does not change with rotation. It is also used to compute the initial conditions for time-dependent simulations of flow in rotating machinery.
Use the Frozen Rotor with Initialization study with the Rotating Machinery, Laminar Flow and Rotating Machinery, Turbulent Flow interfaces, which require the CFD Module, or the Mixer Module plus the CFD Module.
