Abstract

Safe marine operations near a wind turbine monopile are wave field dependent. The wave field around the foundation is used to assess whether the operation can be conducted by evaluating the wave field to operating limit conditions. As a first step to study the wave field around a monopile subjected to wave and current, wave run-up has been simulated with two Navier-Stokes (N-S) solvers: OpenFOAM and DualSPHysics. OpenFOAM uses a Eulerian approach to solve the N-S equations while DualSPHsyics uses a Lagrangian approach. The objective of the present study is to assess the applicability of the two numerical modelling approaches in capturing the wave field around the monopile using wave generation schemes that can be extended to wave and current generation. Existing experimental data of the wave run-up over a monopile under different wave conditions is used as a benchmark. It is found that both approaches give a good agreement for upwave run-up while the downwave run-up in DualSPHysics is slightly underestimated. The results show that both numerical models are reliable tools for studying wave runup and offer two wave generation methods that can be extended for wave-current interactions around a monopile.
