Numerical simulations have been used to analyze the effect that vortices, shed from one flapping foil, have on the thrust of another flapping foil placed directly downstream. The simulations attempt to model the dorsal-tail fin interaction observed in a live bluegill sunfish by Drucker & Lauder 4-6 using Particle Image Velocimetry (PIV). The simulations have been carried out using a Cartesian grid method that allows us to simulate flows with complex moving boundaries on stationary Cartesiandoi:10.2514/6.2005-4760 fatcat:aqgdwnt3zvdmrmclwboion5apa
