The development of marine current turbines arrays has been an active research topic for some years. However, many studies are still necessary in order to fully understand the behaviour of such arrays. One of these studies is the impact of the ambient turbulence on the behaviour of marine current turbines. Indeed recent studies have shown that ambient turbulence intensity highly modifies the behaviour of horizontal axis marine current turbines. Consequently numerical simulations have to represent the ambient turbulence or at least its effects on the performance and wake of the turbines. An other one of these studies is the assessment of interaction effect between turbines in close proximity. In order to highlight these interaction effects, experiments were carried out in the IFREMER flume tank of Boulogne-Sur-Mer. Those experiments focused on elementary interactions between three 3-bladed horizontal axis turbines. In parallel to these experiments, a threedimensional software is developed at LOMC (Université le Havre Normandie) to simulate marine current turbines in a free flow. This manuscript presents the latest numerical developments carried out at LOMC in collaboration with IFREMER in order to take into account the effects of ambient turbulence on the turbines as well as the interactions effects between turbines.
