Abstract
We use a connection between relativistic hydrodynamics
and scalar field theory to generate exact analytic solutions
describing
nonstationary inhomogeneous flows of the perfect fluid
with oneparametric equation of state (EOS) p = p(ε).
For linear EOS p = κε we obtain selfsimilar
solutions in the case of plane, cylindrical and spherical
symmetries. In the case of extremely stiff EOS (κ = 1) we
obtain ''monopole + dipole'' and ''monopole + quadrupole''
axially symmetric solutions. We also found some nonlinear EOSs
that admit analytic solutions.
Key words:
relativistic hydrodynamics; exact solutions.
