Fig. 8. The influence of momentum and hydrodynamics on coasting performance. Coasts
were simulated using the mean parameter values for four ontogenetic stages.
Simulations used the momentum, p, of adults
(p=1.04x10-4 kg m s-1; purple), juveniles
(p=8.05x10-7 kg m s-1; green), large
larvae (p=8.28x10-8 kg m s-1; blue) and
small larvae (p=7.01x10-9 kg m s-1;
orange). Model coasting that included (solid line) and excluded (broken line)
the added mass is shown. (A-C) Curves show the predicted change in body
position as a function of time for coasting simulations in the viscous regime
(Eqn 4), with the body lengths of
(A) small larvae (L=4.35 mm), (B) large larvae (L=8.19 mm)
and (C) juveniles (L=13.81 mm) shown. (D) Simulations of coasting in
the inertial regime (Eqn 8) with
the wetted surface area of adults (S=660 mm2) were run at
each level of momentum.
