Direct power spectral density estimation from structure functions without Fourier transforms
Mark A. Bishop, Sean Oughton, Tulasi N. Parashar +1
Second-order structure functions and power spectral densities are popular tools in the study of statistical properties across scales, particularly for the analysis of turbulent flo…
Energy Flux Decomposition in Magnetohydrodynamic Turbulence
D. Capocci, P. Johnson, S. Oughton +2
In hydrodynamic (HD) turbulence an exact decomposition of the energy flux across scales has been derived that identifies the contributions associated with vortex stretching and str…
New Exact Betchov-like Relation for the Helicity Flux in Homogeneous Turbulence
Damiano Capocci, Perry L. Johnson, Sean Oughton +2
In homogeneous and isotropic turbulence, the relative contributions of different physical mechanisms to the energy cascade can be quantified by an exact decomposition of the energy…
Evolution of similarity lengths in anisotropic magnetohydrodynamic turbulence
Riddhi Bandyopadhyay, William H. Matthaeus, Sean Oughton +1
In an earlier paper (Wan et al. 2012), the authors showed that a similarity solution for anisotropic incompressible 3D magnetohydrodynamic (MHD) turbulence, in the presence of a un…
Cross-helically forced and decaying hydromagnetic turbulence
Axel Brandenburg, Sean Oughton
We study the evolution of kinetic and magnetic energy spectra in magnetohydrodynamic flows in the presence of strong cross helicity. For forced turbulence, we find weak inverse tra…
