AN INCOHERENT a-) DYNAMO IN ACCRETION DISKS
We use the mean-Ðeld dynamo equations to show that spatially and temporally incoherent Ñuctuations in the helicity in mirror-symmetric turbulence in a shearing Ñow can generate a large-scale, coherent magnetic Ðeld. We illustrate this e†ect with simulations of a few simple systems. For statistically homogeneous turbulence, we Ðnd that the dynamo growth rate is roughly qeddy ~1@3qshear ~2@3Neddy...
متن کاملAn Incoherent Dynamo in Accretion Disks
We use the mean-eld dynamo equations to show that spatially and temporally incoherent uctuations in the helicity in mirror-symmetric turbulence in a shearing ow can generate a large scale, coherent magnetic eld. We illustrate this eeect with simulations of a few simple systems. For statistically homogeneous turbulence we nd that the dynamo growth rate is roughly ?2=3 eddy ?1=3 shear N ?1=3 eddy...
متن کاملOn the dynamo driven accretion disks
We add the α− effect in the dynamo driven accretion disk model proposed by Tout & Pringle (1992), i. e., a dynamo model depends on the physical processes such as Parker instability, Balbus-Hawley instability, magnetic field reconnection and α − ω mean field dynamo as well. The α− effect in the dynamo mechanism is determined by the strength of turbulence of the accretion flow. When the turbulent...
متن کاملThe Role of Thermal Conduction in Accretion Disks with Outflows
In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...
متن کاملAn Incoherent � Dynamo in Accretion
We use the mean-eld dynamo equations to show that an incoherent alpha eeect in mirror-symmetric turbulence in a shearing ow can generate a large scale, coherent magnetic eld. We illustrate this eeect with simulations of a few simple systems. In accretion disks, this process can lead to axisymmetric magnetic domains whose radial and vertical dimensions will be comparable to the disk height. This...
