Abstract: SUMMARYTo understand the mechanics of fish swimming, we need to know the forces exerted by the fluid and how these forces affect the motion of the fish. To this end, we developed a 3-D computational approach that integrates hydrodynamics and body dynamics. This study quantifies the flow around a swimming zebrafish (Danio rerio) larva. We used morphological and kinematics data from actual fish larvae aged 3 and 5days post fertilization as input for a computational model that predicted free-swimming dynamics fr… Show more

“…This may be due to the high inefficiency of paddling. Larval fish swim with a propulsive efficiency of around 0.3 (Li et al, 2012), which is about threefold greater than what we have found in most water boatmen (Fig. 10B).…”

“…high circulation and 'jets'). Both vortices and accelerated velocities are hydrodynamic features associated with and directly related to zones of negative pressure in the fluid (Batchelor, 1973;Li et al, 2012), and, for the control lampreys, the gradual development of these hydrodynamic features gradually developed large negative pressure zones in the troughs of the traveling waves ( Fig. 9F; Gemmell et al, 2015).…”

“…However, we have much less of an understanding of the mechanisms through which bending kinematics interact with adjacent fluids to enhance thrust. One effect of bending is that it enhances negative pressure regions of the fluid adjacent to the inflexion point of the bending appendage (Colin et al, 2012;Li et al, 2012;Nakata and Liu, 2012). This serves to accelerate more fluid than fluid around rigid propulsors, which enhances the momentum of the surrounding fluid.…”
