Effect of Aspect Ratio on Optimal Disturbances of Duct Flows
The linear temporal stability of the Poiseuille flow through a rectangular duct is considered. The effect of the duct aspect ratio on the transient growth of disturbances, which causes the so-called subcritical laminar–turbulent transition, is studied numerically. In particular, it is shown that an...
