Looping Smoke Simulation

I came across a video that was experimenting with the design of a Toroidal Fan. In one part of the video, they demonstrated the fan's effectiveness by passing smoke through it, creating a visually very satisfying display. So i tried my best to recreate it inside Houdini with the addition of making it loop!

The File Includes :
- Model of a Toroidal Fan (Modeled outside of Houdini)

- Rest of the Fan Model

- Looping Smoke simulation

- render setup (Mantra + Karma)
