Investigating fish suction feeding using computational fluid dynamics

Abstract: Suction feeding is one of the most common of all aquatic prey capture techniques. In suction feeding events predator fish manipulate the fluid flow around prey to draw them into the mouth. Previous models of this phenomena neglect the fluid-structure interaction between the water and the prey. Here we discuss how to use computational fluid dynamics with an overset grids methodology to investigate suction feeding strikes that captures the fluid structure interaction. Results of the forces experienced by the prey are presented and compared to existing models.
