Abstract

This paper examines a two-dimensional numerical model for analyzing the hydrodynamics of fish propulsion using the OpenFOAM software suite. The study proposes an oscillation method based on the deformation of a mesh rigidly attached to the body. Auxiliary modules for OpenFOAM were developed to automatically determine cruising speed and the power expended on propulsion. The proposed model is verified by comparison with known data.

Keywords

propulsive motion; Navier-Stokes equation; cruising speed; numerical simulation; OpenFOAM.
