Optimal flow rate

WebFeb 7, 2024 · The optimal flow rate is always larger than the flow rate obtained by naively discretizing a sine wave, where the phase shifts are equally spaced by 2 π / N (orange dots). The inset shows the ratio between the optimal flow rate Q ~ max (N) and the flow rate Q ~ sine (N) obtained by discretizing a sine wave, as a function of N.
