Abstract

A two-DoF (degree of freedom) motion model was established for a mechanical pectoral fin. The secondary development of FLUENT (CFD code) software, which is based on the Reynolds-Averaged Navier-Stokes equations (RANS) was adopted. The methods of dynamic mesh and post-processing system of FLUNET were also fully used. The hydrodynamic performances of mechanical pectoral fin in viscous flows were calculated and the calculating results were compared with the latest experimental results. The influences of kinetic parameters on the pectoral fin hydrodynamics were analyzed, which was a basis for the later physical experiments.
