On Generation of magnetic field in astrophysical bodies
Mahendra K. Verma
In this letter we compute energy transfer rates from velocity field to magnetic field in MHD turbulence using field-theoretic method. The striking result of our field theoretic cal…
A new approach to study energy transfer in turbulence
Gaurav Dar, Mahendra K. Verma, V. Eswaran
The unit of nonlinear interaction in Navier-Stokes and the Magnetohydrodynamic (MHD) equations is a wavenumber triad ({\bf k,p,q}) satisfying . The expression for th…
Intermittency in the Burgers and KPZ equation with correlated noise
Mahendra K. Verma
withdrawn; Earlier versions of chao-dyn/9904020 & chao-dyn/9904021 have been combined into one paper.
Energy transfer in two-dimensional magnetohydrodynamic turbulence
Gaurav Dar, Mahendra K. Verma, V. Eswaran
In an earlier paper (physics/0006012) we had developed a method for computing the effective energy transfer between any two Fourier modes in fluid or magnetohydrodynamic (MHD) flow…
Probing Physics of Magnetohydrodynamic Turbulence Using Direct Numerical Simulation
Mahendra K. Verma, Gaurav Dar
The energy spectrum and the nolinear cascade rates of MHD turbulence is not clearly understood. We have addressed this problem using direct numerical simulation and analytical calc…
