摘要：Transient energy growths of two- and three-dimensional optimal linear perturbations to two-dimensional flow in a rectangular backward-facing-step geometry with expansion ratio two are prented. Reynolds numbers bad on the step height and peak inflow speed are considered in the range 0–500, which is below the value for the ont of three-dimensional asymptotic instability. As is w

The critical Reynolds number below which there is no growth over any time interval is determined to beRe= 57.7 in the two-dimensional ca. The centroidal location of the energy distribution for maximum transient growth is typically downstream of all the stagnation/reattachment points of
