【Abstract】

<正>The instability of unsteady streaky flow in a channel under the presence of a constant uniform streamwise magnetic field is investigated with linear stability analysis.The optimal secondary perturbations and their amplifications are calculated by solving iteratively the direct and adjoint governing equations.Without magnetic field,the linear secondary perturbations evolving on
