Abstract: The expansion of the fireball created in Au-Au collisions at $\sqrt{s}=200$ GeV and Pb-Pb collisions at $2.76$ TeV is modelled using relativistic viscous hydrodynamics. The experimentally observed interferometry radii are well reproduced. Additional pre-equilibrium flow slightly improves the results for the lower energies studied.
