Simulations of small-scale turbulent dynamo
A. A. Schekochihin, S. C. Cowley, S. F. Taylor +2
We report an extensive numerical study of the small-scale turbulent dynamo at large magnetic Prandtl numbers Pm. A Pm scan is given for the model case of low-Reynolds-number turbul…
Critical Magnetic Prandtl Number for Small-Scale Dynamo
A. A. Schekochihin, S. C. Cowley, J. L. Maron +1
We report a series of numerical simulations showing that the critical magnetic Reynolds number Rm_c for the nonhelical small-scale dynamo depends on the Reynolds number Re. Namely,…
Self-similar turbulent dynamo
A. A. Schekochihin, S. C. Cowley, J. L. Maron +1
The amplification of magnetic fields in a highly conducting fluid is studied numerically. During growth, the magnetic field is spatially intermittent: it does not uniformly fill th…
From Small-Scale Dynamo to Isotropic MHD Turbulence
A. A. Schekochihin, S. C. Cowley, S. F. Taylor +2
We consider the problem of incompressible, forced, nonhelical, homogeneous, isotropic MHD turbulence with no mean magnetic field. This problem is essentially different from the cas…
