Perturbations dynamics in Keplerian flow under external stochastic forcing
D. N. Razdoburdin
We investigate the dynamics of linear perturbations in Keplerian flow under external stochastic force. To abstract from the details of flow structure and boundary conditions, we co…
Subcritical transition to turbulence in accretion disc boundary layer
V. V. Zhuravlev, D. N. Razdoburdin
Enhanced angular momentum transfer through the boundary layer near the surface of weakly magnetised accreting star is required in order to explain the observed accretion timescales…
Analytic construction of baroclinic tori by non-linear summation
D. N. Razdoburdin
In this paper analytical method for constructing baroclinic flow is presented. Presented method allows the construction of baroclinic tori with significant vertical shear, which ar…
Transient growth of perturbations on scales beyond the accretion disc thickness
D. N. Razdoburdin, V. V. Zhuravlev
Turbulent state of spectrally stable shear flows may be developed and sustained according to the bypass scenario of transition. If it works in non-magnetised boundless and homogene…
Transient dynamics of large scale vortices in Keplerian disk
D. N. Razdoburdin
The mechanism of transition from laminar state to turbulent state in Keplerian disks is still unknown. The most popular version today is generation of turbulence due to magnetorota…
Transient dynamics of perturbations in astrophysical disks
Dmitry N. Razdoburdin, Viacheslav V. Zhuravlev
This paper reviews some aspects of one of the major unsolved problems in understanding astrophysical (in particular, accretion) disks: whether the disk interiors may be effectively…
