DESCRIPTION:"Magnetohydrodynamic turbulence follows Kolmogorov scaling"\n\n
  \n\nPresented by Dr. Mahendra Verma\, Professor\, from the Indian Institut
 e of Technology Kanpur\, India\n\n \n\nTwo competing theories of magnetohyd
 rodynamic (MHD) turbulence are given by Iroshnikov-Kraichnan and Kolmogorov
 . The problem of scaling in isotropic magnetohydrodynamic (MHD) turbulence 
 has remained unresolved\, with competing predictions of k-5/3 (Kolmogorov) 
 and k-3/2 (Iroshnikov-Kraichnan) scalings. In this talk I will present  res
 ults of high-resolution numerical simulations on 81922 and 10243 grids. The
  computed energy spectra are closer to k-5/3 than k-3/2. More importantly\,
  our detailed analyses of structure functions\, intermittency exponents\, a
 nd energy fluxes demonstrate robust support for Kolmogorov scaling.  Our fi
 ndings firmly establish Kolmogorov scaling in MHD turbulence and significan
 tly improve the theoretical foundations for modeling astrophysical turbulen
 ce and dynamo processes.
