We propose a generalized accretion disk viscosity prescription based on hydrodynamically driven turbulence at the critical effective Reynolds number. This approach is con- sistent with recent re-analysis by Richard & Zahn (1999) of experimental results on turbulent Couette-Taylor flows. This new -viscosity formulation is applied to both selfgravitating and non-selfgravitating disks and is shown to yield the stan- dard -disk prescription in the case of shock dissipation limited, non… 
On the prescriptions of viscosity in an accretion disk model
We have investigated a model of an accretion disk around a supermassive black hole in active galactic nuclei (AGN). Three kinds of prescription of viscosity have been examined. It is found that the
A numerical study of self-gravitating protoplanetary disks
The effect of self-gravity on protoplanetary disks is investigated. The mechanisms of angular momentum transport and energy dissipation are assumed to be the viscosity due to turbulence in the
Vertically self-gravitating ADAFs in the presence of toroidal magnetic field
Force due to the self-gravity of the disc in the vertical direction is considered to study its possible effects on the structure of a magnetized advection-dominated accretion disc. We present
Observing dust grain growth andsedimentation in circumstellar discs
In the present thesis, the observational effects of dust grain growth and sedimentation in circumstellar discs are investigated. The growth of dust grains from some nanometres in diameter as found
Gravitating discs around black holes
Fluid discs and tori around black holes are discussed within different approaches and with the emphasis on the role of disc gravity. First reviewed are the prospects of investigating the

Evolution of Protoplanetary Disks Including Detailed Chemistry and Mineralogy
The earliest phase of evolution of planetary system is determined by the intimate coupling of a number of physical and chemical processes: turbulent hydrodynamic flows under the action of gravity,
The Mid-infrared - Hard X-ray Correlation in Active Galactic Nuclei
Active Galactic Nuclei (AGN) are among the most fascinating Astronomical objects. They are the most powerful non-transient sources in the Universe and have been studied extensively for more than 40
