Abstract
The hydrokinetic potential in rivers is proportional to the flow rate, where it crucial to find high velocities to make it viable to install hydrokinetic turbines. In some cases, due to the large scales, the velocity measuring is a problematic process and demands expensive equipment, like acoustic Doppler current profiles (ADCP). In this view, this work intends to demonstrate a low-priced methodology of Large-Scale Particle Image Velocimetry (LSPIV) with drone images for measuring the velocities on the river’s surface. The tests were carried on São Bartolomeu river in Federal District, Brazil. The presence of trace-marks also was analyzed, where some sawdust was deployed on the river to improve the LSPIV results. The measurements were compared to traditional ADCP results.
