Verification and validation in computational fluid dynamics: application to both steady and unsteady rowing boats numerical simulations

摘要

This paper focuses on the Verification and Validation procedure (V&V) applied in the particular case of rowing boats with both steady and unsteady surge motions. The different approaches proposed in literature are applied and compared to better estimate the a posteriori error. In order to compare numerical results with towing tank experimental data and exactly make validation of the code ICARE3D, the basin geometry (width = 5 m, depth = 3 m) is taken into account. The validation procedure is applied with a set of six grids. For unsteady simulations, unsteady resistant coefficient is compared to experiments in terms of time histories and Fourier components.
