Abstract

In this paper a RANS (Reynolds-averaged Navier–Stokes) model is developed to determine the floating solar platform response in random wave regimes. The model takes advantage of the finite volume solver and the Volume of Fluid method (VoF) to solve the two-phase fluid flow which is enhanced by the k-ω SST model. Initially the model emerged for simulation of a floating solar platform in regular waves and mesh convergence and stability analysis were carried out to assess the accuracy of the model. The numerical model is fostered currently for irregular waves and the performance of the numerical model is investigated for frequency ranges of the JONSWAP spectrum. A set of experimental data is compared with the numerical results for verification and the range of validity of the model is outlined. The responses show the presence of higher order harmonics, and, with further adjustments, the model can be utilized to study steeper non-linear waves. Thus, a useful approach in studying the responses of the solar platform and its sensitivity for irregular waves can be achieved which could be crucial to identify resonance and design of solar platforms along with mooring lines.
