Non-locality of the Turbulent Electromotive Force

  title={Non-locality of the Turbulent Electromotive Force},
  author={Abhijit Bhausaheb Bendre and Kandaswamy Subramanian},
The generation of large-scale magnetic fields (B) in astrophysical systems is driven by the mean turbulent electromotive force (E), the cross correlation between local fluctuations of velocity and magnetic fields. This can depend non-locally on B through a convolution kernel 8 9 . In a new approach to find 8 9 , we directly fit the time series data of E versus B from a galactic dynamo simulation using singular value decomposition. We calculate the usual turbulent transport coefficients as… Expand
