The current study presents flow measurements around a hydrokinetic turbine using a Horizontal Acoustic Doppler Current Profiler (HADCP). HADCPs are often used to estimate the water discharge rate and flow velocity however, they can also be used to characterize the near-surface flows; this includes the wake generated by a surface mounted hydrokinetic turbine. Tests are conducted around a 22-kW cross flow hydrokinetic turbine at the Canadian Hydrokinetic Turbine Test Centre located on the Winnipeg River. The goal of the study is to verify the utility of the HADCP for turbine characterization but also to examine the flow around a turbine, especially the inflow and wake regions.
Evaluation of the wake around a 22-kW hydrokinetic turbine is located in Canada.
