摘　　要：Indonesia’s vast maritime territory offers a unique opportunity for harnessing the potential Energy of seawater currents.This study explores the effectiveness of a combined Savonius and propeller-type turbine system.The Savonius turbine,known for its efficiency in capturing ocean currents due to its large sweep area,is combined with a propeller-type turbine to enhance rotational speed and power generation.A novel approach is employed to induce turbulence and optimize energy extraction,first channeling water through the propeller turbine and then into the Savonius turbine.A comprehensive investigation is conducted through simulations and experimental tests within a controlled tunnel environment.The study explores the performance of two-bladed and three-bladed Propeller-Savonius configurations at varying inlet water velocities(0.1,0.3,0.6 and 1.0 m/s).The simulation incorporates a turbulence model with 5%intensity and a hydraulic diameter of 0.216 m.Results indicate that the proposed configuration achieves a maximum power output of 2.0293 W with an impressive efficiency of 63.339%in simulation.Concurrently,experimental testing yields a peak efficiency of 61.335%and turbine power of 0.3951 W.The findings demonstrate the feasibility of the combined turbine system and highlight the importance of turbulence in optimizing energy extraction from seawater currents.This research contributes valuable insights into the design and performance of hybrid turbines for harnessing oceanic Energy,emphasizing the potential for sustainable power generation in maritime regions.The methodology and results presented herein offer a foundation for further exploration and refinement of seawater current energy conversion technologies.
