[Verse]
The tangential velocity
(Of the vorticity)
It’s in the whirl
(It’s in the swirl)
[Chorus]
I am…
Caught up in the angular momentum
(I am)
Spinning round (and round again)
[Bridge]
Rotational vortex
(Chaos is complex)
[Instrumental, Guitar Solo]
[Verse]
The tenacity…
(Of the vorticity)
Grip on the whirl
(Giving it a twirl)
[Chorus]
I am…
Caught up in the angular momentum
(I am)
Spinning round (and round again)
[Bridge]
Rotational vortex
(Yes, this chaos is complex)
[Outro]
Rotational vortex
(Yes, this chaos is complex)
A SCIENCE NOTE
Key Characteristics
- Vorticity and Rotation:
- Vorticity measures how much and in what direction a small fluid element rotates about its own center.
- It does not directly indicate the speed (magnitude of velocity) of the flow but reflects the circulation and rotational nature of the motion.
- In a Vortex:
- High vorticity indicates strong rotational motion.
- Zero vorticity corresponds to irrotational flow (e.g., laminar flow without rotation).
- Units:
- Vorticity is measured in radians per second (rad/s) in SI units, representing angular velocity per unit area.
The velocity typically increases as matter spirals inward in a vortex, due to the conservation of angular momentum. This principle applies to various types of vortices, whether in fluids, air, or astrophysical systems like accretion disks around black holes.
