The present study proposes a reservoir computing reduced-order model (RCROM) of the
post-stall flow around the National Advisory Committee for Aeronautics 0015 airfoil based on
the time series velocity field, and the estimation accuracy of the RCROM is evaluated
compared to that of a linear reduced-order model (LROM). The data were experimentally
obtained by particle image velocimetry at a chord Reynolds number of 6.4× 10 4 and an
angle of attack of 18. The low-dimensional description of the velocity field can be obtained …
