Research on the Rapid Closing Jet Mechanism of Pistol Shrimp’s Claws Based on Fluid Dynamic Grid

The predation behavior of the pistol shrimp is extremely special, and process will produce a huge popping sound, which has caused extensive research by scholars from all over world. This article carried out study on rapid closing jet mechanism shrimp’s claws. A theoretical model, based hydrodynamic characteristics seawater theory fluid-structure coupling, was proposed for interaction between claws seawater. simulation model established using finite volume software Fluent, verified fluid dynamic grid. studied influence different models results. effects claws’ angular velocity acceleration were analyzed, provides basis development new underwater kinetic energy weapons.
