We present our theoretical investigations on the local behavior of vorticity formations in
accreting flow of binary stars. The vortices are considered as non-single patterns that are
moving along with the flow, interacting with the matter there – maintained by gas - dynamical
laws. The vortex - flow density relation factor is suggested. Then we study of how much its
values are relative to the stability of the vortices themselves and to the entire accretion disc
structure. Further dynamics of the disc matter could result in the situation when a single vortex
meets other vortical formations. According to the physical conditions and parameters, these
vortices could merge forming a new bigger tick composition with properties rather close to that
of the density wave. In the second case, they could stay as individual vortices, which are held in
a cluster and moving as a whole wave configuration.
