Résumé
A laboratory-scale Archimedes screw pump was tested in a fully transparent apparatus. Using two cameras, the free surface action of the screw buckets were quantified for the first time during experimental operation. This kind of data has been gathered using computational fluid dynamics, but never in a real Archimedes screw pump. It was observed that rotation speed impacted the amount of leakage experienced during operation, which created a variation in bucket fill height along the length of the operating screw - called the fill height gradient. Further, a sloshing action was observed in the screw buckets, which was suggested to be impacted by rotation speed and flow regime. This study demonstrated new experimental methods that used video footage and open-source annotation software to gather reliable, quantifiable data from free-surface flows. This novel experimental approach can be used to gather reliable, inexpensive data from complex geometries.
