Image processing technique for hydraulic application

Abstract

In this paper, we present techniques Surface Flow Image Velocimetry (SFIV) that is a practical extension of Particle Image Velocimetry method (PIV). In particular, this technique is to evaluate the behavior on the surface flow for complex flow. SFIV allows to measure complex surface velocity fields for engineering applications. The objective of this work was the application of the SFIV technique to determine the velocity fields and their hydraulic efficiency of grated inlet, making a comparison between the programs able to correlate images like Digiflow or PIVlab program.
