Dipole-source localization using biomimetic flow-sensor arrays positioned as lateral-line system

摘要

Flow-sensor arrays can be used to extract spatio-temporal flow signatures rather than average or local flow quantities. In this paper, we focus on the equivalent of a fish lateral-line sensor array in air and assess the ability of our artificial flow-sensor arrays to detect flow-velocity distributions generated by a vibrating sphere. The effect of various source parameters on the source-distance determination is investigated. The measured flow patterns along a virtual lateral-line are found to be in excellent agreement with theory and are used successfully to demonstrate source-distance determination.
