Summary
We consider fluid dynamics and solutions. We define the ideal fluid and viscous fluid dynamics (governed by the Navier–Stokes equations) and their relativistic generalizations. The notion of vorticity and fluid helicity is defined, and the wave of small fluid fluctuations is found. Finally, we define fluid vortices and knotted solutions.
