Abstract
Wave energy has been widely studied in the field of computational modeling generating observations in several fields of research. Oscillating Water Column (OWC) devices have been studied in the search for results that can be used as a recommendation for chamber and turbine design. Main goal is to obtain the best possible performance in the transformation of wave energy into electrical energy. Wave motion and water iteration with the device are simulated with Computational Fluid Dynamics (CFD) codes. Usually, laminar models are used and just a few works include turbulence in the simulation. In this sense, present work compares laminar and turbulent simulations aiming to determine best way to simulate this type of problem. Preliminary comparisons for velocity vectors and magnitude have shown that k-ω turbulent model presents greater difference results in relation all other models studied (k-ε and Spalart Allmaras).
