Simulations for Modelling the Carrier Press Distribution of Artificial Lateral Line Based on the Computational Fluid Dynamics

Abstract

Artificial lateral line (ALL) can detect underwater hydrodynamic stimuli by means of sensing the press with sensors. The computer simulation can break the restrictions of sensor accuracy and obtain the press distribution of ALL carrier. In this paper, the simulation is first conducted in uniform flow to establish the relations among the press, flow velocity and geometry. Then the fields behind the circle and square obstacles are simulated to get the transient flow feature between press, geometry and time. The first peak frequency of press curve is close to the vortex shedding frequency. At last, the recognition of different field and obstacles are obtained. The frequency and waveform could be the evidence to distinguish flow field.
