Rans-based model for simulating hydrodynamic variations around a rigid ship hull

The hydrodynamic variations around floating structures in the naval ship applications are crucial to study its stability and hull optimization. The choice of the hull shape is capital to reduce the dispenses associated with energy. We address one-way fluid–structure interaction for a rigid (fixed) hull under a fluid dynamics model. Structural dynamics are not solved. The developed model is based on the coupling between Reynolds Averaged Navier-Stokes (RANS) equations and a k −e turbulence model. This model extends naturally several models available in the literature including classical RANS models (steady and unsteady) and several RANS based models that neglect the turbulence phenomena (including transport and diffusion). The coupled RANS-based model is implemented numerically using finite element methods. We have chosen a two-dimensional ship hull 2D model to show how modelling can address turbulent flows around fixed structure. The numerical results obtained are encouraging and can allow us to study their optimization for the preliminary phase with a certain precision.
