The realm of relativistic hydrodynamics
Hydrodynamics or fluid dynamics is the study of the behaviour of fluids such as water and air - water flowing down a canal, but also, for instance, air flowing around an airplane fuselage. The term relativistic hydrodynamics (or relativistic fluid dynamics) refers to the study of flows in the arena of special or of general relativity. Special relativity will come into play when the velocities attained by certain portions of the fluid or by the fluid as a whole approach the speed of light. General relativity comes into play when there are sufficiently strong gravitational fields - either because the fluid's environment features such fields, or because the mass and energy of the fluid are sufficient to generate their own strong gravity.
