Larger wavelengths suit hydrodynamics of carangiform swimmers

We examine the connection between physiology and wavy kinematics of carangiform swimmers, such as Jack, Tuna, Sunfish. Using high-fidelity numerical simulations for flows over Jack Fish models obtained through reconstruction high-speed images real natural it was revealed that undulation with larger wavelengths improves hydrodynamic performance swimmer in terms better thrust production by caudal fin, lower drag on trunk, reduced power consumption trunk.
