Abstract

Motivated by the importance of investigating the hydrodynamic performance of Verti-cal Axis Marine Current Turbine (VAMCT) in field like to real marine environment, this work presents numerical simulation of VAMCT in both steady and unsteady current velocity. Three bladed turbine is examined in order to evaluate the performance of VAMCT in fluctuating current velocity. Turbine model is studied using a time-accurate Reynolds-Averaged Navier-Stokes (RANS). Transient rotor-stator model with sliding mesh technique was used. User-Definition Function (UDF) is created to simulate random fluctuated current velocity. The results show that, there are significant decrease in power efficiency in unsteady current compared with steady case.
