Fish-like body motions are modeled and the impact of vortices generated by the motion is analyzed. Specifically, numerical investigations of self-propelled swims of thunniform fish are performed in a low Reynolds number, viscous and nearly-incompressible regime of flow. By computing the flow around a deforming fish-like body, the formation and accumulation of large vortex structures at the anterior and their effect on the overall motion is investigated in detail. Large vortical structures whichdoi:10.2514/6.2016-3254 fatcat:4ckvcnf6mbhlloxvno3hkj3fne
