Abstract

Among the various renewable energy sources that can be explored, there is the energy contained in sea waves. The WaveMIMO methodology is used for the numerical generation of irregular waves based on realistic sea states and consists of processing spectral data to obtain orbital velocity profiles of wave propagation, which are imposed as a boundary condition (BC) in a numerical wave channel. In this sense, this study evaluates parameters for the application of this methodology, investigating the discretization of the prescribed velocity BC imposition region, the mesh sensitivity in the free surface region, the time step used and, finally, the location of the velocity vector in each segment of the prescribed velocity BC imposition region. Therefore, realistic data were considered from a point close to the coast of the municipality of Mostardas, in the state of Rio Grande do Sul, obtained from the spectral model TOMAWAC. Results indicated that, comparing the best and worst case evaluated, improvements of 6.58% and 7.60% were obtained in the metrics considered when evaluating the results.
