Resumo
A numerical model combining the actuator line methodology with the URANS simulations techniques (ALM) isused to compute the flow through a hydrokinetic 4-blades turbine (Re = 105), the wake and the efficiency of the machine.The ALM/URANS methodology is compared with the results obtained to the full-geometry URANS simulations to validatethe simplified methodology. The results showed that the ALM has a satisfactory approximation, especially for far-wakeszones, which make the ALM an excellent tool for turbines iterations inside farms. A performance analysis also shows thatboth methodologies can reproduce the same power coefficient curve
