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:

1. Fluent Launcher
   1. Select double precision
   2. 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.
2. Models
   1. Edit viscous
      1. K-omega
      2. SST
3. Cell zone conditions
   1. Edit Fluid
      1. Enable Frame Motion
      2. Specify angular velocity to be -2.22 m/s

Boundary Conditions

We now specify the boundary conditions. 

Summary of steps in the above video:

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