Figure 12


Fig. 12. Unsteady fluid forces acting on the fish surface for the five segments (1-5) from head to tail. The forces on the left half are colored in blue, the ones on the right half in red, and the black line plots the cumulated force of left and right part. The total force in swimming direction C|| is plotted in green as reference. Positive values relate to thrust, negative to drag. Results for the efficient swimming case are plotted in (A) and for the fast swimming motion in (B).
