Mechanics of Undulatory Swimming in a Frictional Fluid
Figure 7
Comparison of head drag and net force on the model sandfish from the simulation and empirical force relations.
A: Head drag ( on the head) as a function of time for
(green represents the empirical force relations and black represents simulation) and
(cyan represents the empirical force relations and blue represents simulation). The forward speed for
is re-plotted from Fig. 3B as the gray line to show relative phasing. B: The net force on the body (including head) in the forward direction as a function of time for
(magenta) and
(red). Bars between (A) & (B): The average values of the net forces and the head drag are given in corresponding colors. Uniform bodies were used in the simulations.
