| description | In the development of an air-turbine with self-pitch-controlled blades for wave energy conversion,
existence of hysteretic characteristics in a reciprocating flow has been examined. In
order to clarify the validity of the analysis, a numerical simulation has been made by use of
the experimental results obtained from a steady unidirectional flow condition. The comparison
between the analysis and experiment has shown that the quasi-steady analysis is
reasonable accurate for predicting the performance. The running and starting characteristics
have also been investigated analytically taking into account the blade turning process
during pitch. |
