SYSTEMS DESIGN REVIEW Team Bass

BACKGROUND Suction Feeding is a method used by telost fish to force food and water in their mouths. To do this, the fish must create a pressure drop between the inside of the mouth and the outside water by expanding the buccal cavity prior to opening the mouth. This causes a fluid flow into the fish. Particle Image Velocimetry (PIV) and Doppler Ultrasound technology are widely used to visualize flow of fluid internally and externally. PIV is most useful for external fluid flow since the internal fluid must be optically accessible. In the scenario when that is not the case, Doppler Ultrasound is used to see through various membranes to visualize internal fluid flow. The drawbacks of these technologies include inaccessibility to internal fluid for optimal visualization and inaccuracies in ultrasound equipment.

PROBLEM STATEMENT Currently, the understanding of fluid flow during suction feeding inside the mouths of fish is relatively nonexistent. Up to this point in time, there has only been one test rig employed to collect data on this subject (using Particle Image Velocimetry (PIV) technology to observe fluid flow outside of fish). The goal of this project is to design and build a test rig that utilizes both PIV and Doppler Ultrasound (DUS) technologies; the device will have the ability to output streamlines of fluid flow in and around the mouth of a largemouth bass, as well as capture live video/images of how this unique method occurs. To do this, the two selected technologies must work synchronously both as data acquisition tools and as verification checks on one another. The resulting design and prototype will adhere to safety and size constraints while including all specialized concepts required for specific research. The data collected by this test rig will be of key importance in fully understanding the entire physics behind suction feeding in fish.
