Description
Simple and exact solutions of relativistic hydrodynamics are
presented, including the first exact solution of relativistic
hydrodynamics with non-zero total angular momentum, an important
characteristics of mid-central and peripheral heavy ion collisions.
The consequences of these new solutions are explored in data
analysis. The effects of longitudinal work, acceleration and the
rotation of the fluid are taken into account in an advanced estimate
of the initial energy density, temperature, pressure and the life-time
of the reaction.
This advanced estimate of the initial energy density yield values that
are significantly larger in Pb+Pb collisions at LHC energies than the
15 GeV/fm**3 initial energy densities obtained from Bjorken's estimate.
