SGER: Confined Steady Streaming Around Bodies of Complex Shape: A Hypothesis of How Fish Directionalize Sound

摘要CTS-0132695M。佐治亚理工学院尤达，佐治亚理工学院这项SGER提案的目标是研究高度受限流体几何结构中复杂形状的振荡钝体所引起的稳定流动。据推测，鱼通过利用内耳中的这种流动来确定入射声音的方向。如果这一“听觉视网膜”假说被证明是正确的，那么它可能会带来一种新的感觉生物学范式，并有可能应用于人类的听力。在工程实践中，这一假设可能导致紧凑和灵敏的水声换能器。

AbstractCTS-0132695M. Yoda, Georgia Institute of TechnologyThe objective of this SGER proposal is to study steady streaming flows due to oscillating bluff bodies of complex shape in highly confined fluid geometries. It is hypothesized that fish determine the direction of incident sound by exploiting such flows in their inner ears. If proved to be correct, this "auditory retina" hypothesis could lead to a new paradigm in sensory biology with possible application in human hearing. In engineering practice, this hypothesis could lead to compact and sensitive underwater acoustic transducers.
