Abstract

AbstractNumerical methods are essential for predicting aerodynamic phenomena and developing new technologies in Fluid Mechanics. Therefore, improving computational techniques to visualize flow, determine aerodynamic coefficients, study flow phenomena, and observe wave-structure interaction is crucial for understanding phenomena related to CFD (Computational Fluid Dynamics), with utility in various industrial applications, as it is the objective of the project linked to the OTIC (Offshore Technology Innovation Center), both in the initial phases of the project and in more advanced phases (detailed project). The present work aims to understand and observe the behavior of a structure subjected to external forces from a sea wave, taking into account the geometry of the structure and the imposed conditions, through the DualSPHysics software, which uses the Lattice-Boltzmann method to solve the Boltzmann equation. With the main support of a GPU (Graphics Processing Unit) to perform the simulation and obtain the results through SPH (Smoothed Particle Hydrodynamics) method. This method, along with the coupling of MoorDyn and Project Chrono, allows the study of the behavior of floating bodies under the action of periodic or random waves. It is proposed, therefore, to evaluate the potential of the method to describe the behavior of the structure, comparing it with data already present in the literature of similar cases. Finally, after obtaining the results, simulations of the behavior of the structures to be used in the OTIC under some imposed operational conditions will be carried out.Keywords: CFD (Computational Fluid Dynamics), SPH, Smoothed Particle Hydrodynamics, wave impact, Offshore Wind Turbines, wave-structure interaction, Lattice-Boltzmann, DualSPHysics, and MoorDyn.
