Dataset for: Biomimetic models of fish gill rakers as lateral displacement arrays for particle separation

Ram suspension-feeding fish such as herring use gill rakers to separate small food particles from large water volumes while swimming forward with an open mouth. Fish gill raker function was tested using 3D-printed conical models and computational fluid dynamics (CFD) simulations over a range of slot aspect ratios. (See CFD simulation output in Dryad dataset: case and data files for ANSYS Fluent 19.1 CFD simulations.)
Our hypothesis predicting the exit of particles based on mass flow rates, dividing streamlines (i.e., stagnation streamlines) at the slots between gill rakers, and particle size was supported by the results of experiments with physical models in a recirculating flume. (See R code with embedded comments in Dryad dataset to test Hypotheses 1 and 2 for particle exit/trapping.)
Particle movement in suspension-feeding fish gill raker models was consistent with the physical principles of lateral displacement arrays (“bump arrays”) for microfluidic and mesofluidic separation of pa..., The following information is also provided as a \"README\" file.
