Perfect fluids are idealized models in which these possibilities are neglected.
A related concept is the perfect fluid equation of state used in cosmology.
Specifically, perfect fluids have no shear stresses, viscosity, or heat conduction.
The RHIC experiments also discovered that this matter is in fact strongly interacting and nearly a perfect fluid.
For a perfect fluid, another equation of state relating density \ rho and pressure p must be added.
For such fluids, specific heats and \ gamma are assumed to be constant and invariant with temperature ( a thermally perfect fluid ).
With the stress energy tensor for a perfect fluid, we substitute them into Einstein's field equations and the resulting equations are described below.
Perfect fluids admit a Lagrangian formulation, which allows the techniques used in field theory, in particular, quantization, to be applied to fluids.
Perfect fluids are often used in general relativity to model idealized distributions of matter, such as the interior of a star or an isotropic universe.
When the energy-momentum tensor represents a perfect fluid, every Killing vector field preserves the energy density, pressure and the fluid flow vector field.
