N2 - The utilization of recurves on vertical seawalls reduces overtopping without drastic increases in the structures’ freeboard. As part of ISOPE22 blind test challenge, an in-house developed computational fluid dynamics code is used to simulate the breaking of waves on a vertical seawall and the interaction of the violent up-rushing flow with the recurve. The code combines recent advances which speed-up the solution of Poison’s equation, with an immersed boundary method and a Large Eddy Simulation model. The comparison of the numerical results with the experimental data provided by the organisers shows a satisfactory reproduction of the wave conditions in the flume and a non-negligible underestimation for the predicted peak pressures. This, with a computational cost of approximately 2 hours per wave period.
