海水直接驱动式Wells透平的设计与分析OA

Focusing on the Wells turbine in oscillating water column devices,the study aims to address the issues of low wave energy conversion efficiency,narrow operating range and poor self-starting performance.Using kinetic simulation and analysis methods,a seawater direct-drive Wells turbine power generation device composed of float,connecting rod,impeller and motor was designed and evaluated.Through simnlating the impeller's torque and power output under different water depths,It revealed that both torque and power significantly increased with depth.Within the 3 m to 15 m depth range,the average torque increased from 28.6N·m to 239.2N·m,and the power increased from 198.1W to 4969.5W,demonstrating good energy absorption performance.The research also indicated an optimal water depth beyond which energy production no longer increases.There fore,system design should balance cost,complexity,and energy capture efficiency to determine the most reasonable configuration.
