  Dynamics of waves generated by scopes in gas centrifuges (GC) for isotope
separation is considered. The centrifugal acceleration in the GC reaches values
of the order of $10^6$g. The centrifugal and Coriolis forces modify essentially
the conventional sound waves. Three families of the waves with different
polarisation and dispersion exist in these conditions. Dynamics of the flow in
the model GC Iguasu is investigated numerically. Comparison of the results of
the numerical modelling of the wave dynamics with the analytical predictions is
performed. New phenomena of the resonances in the GC is found. The resonances
occur for the waves polarized along the rotational axis having the smallest
dumping due to the viscosity.
