Gadelho, J.F.M., Rodrigues, J.M., Lavrov, A. e Guedes Soares, C. (2015), “Determining hydrodynamic coefficients of a cylinder with Navier-Stokes equations”, Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor & Francis Group, London, UK, pp. 1001-1008
A methodology is presented to numerically determine the hydrodynamic coefficients of an oscillating 2D rigid body, using a time domain Navier-Stokes model. Results for heave and sway motions of a cylinder in deep water are presented and compared with a practical case. The simulations have been performed with the open source Computational Fluid Dynamics (CFD) OpenFOAM software. Results demonstrate a good agreement of the added mass and damping coefficients between the calculated values and the ones obtained with potential flow formulations.
