However, the technology is still in its early stages, with very few commercial installations operating worldwide and many turbine designs still in the prototype phase. A critical factor in transitioning from prototype to functioning installations is the ability of researchers, government agencies, and commercial entities to rapidly evaluate turbine performance in laboratory settings, as well as the capacity to assess field performance with limited data. To address this need, HKTs were experimentally tested in a racetrack flume at the Ecohydraulics and Ecomorphodynamics Laboratory (EEL) at the University of Illinois, Urbana-Champaign. Optimal locations and durations for flow measurements to characterize the mean streamwise velocity and turbulent intensities in the turbine wake were identified. Recommendations were provided on predicting wake evolution using only a single measurement in the turbine's near wake. Additionally, a Python package was created to clean, analyze, and visualize the flow around HKTs. This tool is versatile and can be used by researchers working with acoustic Doppler velocimetry (ADV) across various applications, not just HKT research. This package is now available on Github for its use by the research community. Another significant challenge in the assessment of this technology is the limited knowledge on the optimization and design of HKT arrays. Unlike the typically permanent installations of wind farms, HKT arrays often require dense packing for quicker and more convenient deployment, necessitating accurate power and wake predictions that consider the effects of neighboring turbines under depth-limited and width-limited flows. We address these issues through the analysis of a series of experiments in which the wake of a HKT with different incoming flow characteristics was measured. These findings have significant implications for the design and optimization of HKT arrays, particularly concerning turbine positioning, structural requirements, and expected power fluctuations."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Development of an experimental framework for hydrodynamic characterization of hydrokinetic turbines in laboratory facilities"]}]}],"canonical_facts":{"dc:contributor":["Tinoco, Rafael"],"dc:creator":["Drimer, Jacob Braxton"],"dc:date":["2024-07-16","2024-08"],"dc:description":["Submission original under an indefinite embargo labeled 'Open Access'.
