text: Coriolis force effects on shear flows are important in geophysical and astrophysical
contexts. We report a study on the linear stability and the transient energy growth
of the plane Couette flow with system rotation perpendicular to the shear direction.
External rotation causes linear instability. At small rotation rates, the onset
of linear instability scales inversely with the rotation rate and the optimal
transient growth in the linearly stable region is slightly enhanced ∼Re2. The
corresponding optimal initial perturbations are characterized by roll structures
inclined in the streamwise direction and are twisted under external rotation.
At large rotation rates, the transient growth is significantly inhibited and hence
linear stability analysis is a reliable indicator for instability.
