Physics Setup
Governing Equations
In the following video, we go into FLUENT and specify the governing equations that we will use.

Summary of steps in the above video:
- Fluent Launcher
- Select double precision
- Select parallel and choose the number of cores, I recommend using as many as you have but note that you need a special HPC license if you choose to use more than 4 cores.
- Models
- Edit viscous
- K-omega
- SST
- Cell zone conditions
- Edit Fluid
- Enable Frame Motion
- Specify angular velocity to be -2.22 m/s
Boundary Conditions
We now specify the boundary conditions.

Summary of steps in the above video:
- Boundary Conditions
- Inlet
- Velocity magnitude: 12m/s
- Inlet-Top
- Component (X,Y,Z): (0,0,-12m/s)
- Blade
- Default, wall
- Periodic 1 and Periodic 2
- Change to Interface
- Mesh Interface
- Click Create/edit
- Name the mesh interface periodic
- Enable Periodic Boundary Condition
- Enable matching
- Type is Rotational
- Offset angle is 120 degrees
- Choose the interface zones to be periodic 1 and periodic 2
