Fig. 7. (A) Representative velocity field including vectors near the aft region of
a steadily swimming squid during jet emission, U=25 cm
s-1, t=0.3 s,
t/
tj=0.5. In (A) the aft section of the
squid is shown in white. Every other vector has been removed from the original
data for clarity. (B) The sub-region of the velocity field in A surrounding
the jet. The region was rotated so that the jet axis (x') is
horizontal and a regular grid of vectors was interpolated at the approximate
resolution of the original data. The white regions in the lower left- and
right-hand corners are regions of no data.
