Hysteretic Characteristics of Wells Turbine For Wave Power Conversion
TL;DR: In this paper, an unsteady 3-dimensional Navier-Stokes numerical simulation of the Wells turbine was performed and the authors found that the hysteretic behavior was associated with a streamwise vortical flow appearing near the blade suction surface.

Performance of the Wells turbine at starting
S. Raghunathan,C. P. Tan +1 more
TL;DR: In this article, the authors investigated the Wells turbine and its difficulty in running up to operational speed when started from rest (known as "crawling") and showed that a high solidity and a low hub-to-tip ratio rotor is required to avoid crawling.
