Abstract

It is shown that the lowest (second) order truncation of the Carleman linearization of the fluid equations (C2) recovers not only the initial transient of the time evolution but also its late stage, namely the steady-state solution. This asymptotic property is first proved analytically for the decaying logistic with external forcing and then shown to hold to a significant degree of accuracy also for the fairly more complex case of two-dimensional fluid flows at moderate Reynolds number. This time-asymptotic property opens interesting prospects for the simulation of steady-state solutions of the fluid equations on quantum computers.
