Magnetic Fields and Passive Scalars in Polyakov's Conformal Turbulence | G. Ferretti

3 Dec 1992 | Journal: | Europhys.Lett. 22 (1993) 639 | Subject: | hep-th | Abstract: | Polyakov has suggested that two dimensional turbulence might be described by a minimal model of conformal field theory. However, there are many minimal models satisfying the same physical inputs as Polyakov’s solution (p,q)=(2,21). Dynamical magnetic fields and passive scalars pose different physical requirements. For large magnetic Reynolds number other minimal models arise. The simplest one, (p,q)=(2,13) makes reasonable predictions that may be tested in the astrophysical context. In particular, the equipartition theorem between magnetic and kinetic energies does not hold: the magnetic one dominates at larger distances. | Source: | arXiv, hep-th/9212021 | Services: | Forum | Review | PDF | Favorites |
