The hydrokinetic rotor serves as a critical component in the system of hydropower utilization. Advantages of the drag-type rotor have been recognized while the disadvantages of low efficiency are appreciable. To improve the performance of the drag-type rotor, studies have been performed from multiple aspects. The present study summarized recent achievements of this rotor branch. Particular, emphasis was placed on the relation between flow characteristics and operation performance of the rotor. A systematic description of the recent achievements and methods pertinent to the drag-type rotor is expected to motivate more fruitful work, thereby extending the application of such a promising rotor.
