摘要：Hydrodynamical or MHD instabilities have been proposed as explanations for the quasi-periodic
oscillations observed in microquasars. One of them is the Rossby wave instability that have been
studied in the case of an accretion disc to explain accretion in a non-magnetised disc (Lovelace,
1999). So far all numerical studies regarding the non-linear behaviour of this instability have been
done using a two dimensional framework (r, q), here 3D numerical simulations of the instability
are presented .
