Magnetic Field Amplification Associated with the Richtmyer-Meshkov Instability

, 2012
The amplification of a magnetic field due to the Richtmyer-Meshkov instability (RMI) is investigated by two-dimensional MHD simulations. Single-mode analysis is adopted to reveal definite relation between the nonlinear evolution of RMI and the field ...
