Analysis of Bubble Curtains for Flow Shaping
The aim of this semester project is to analyze, evaluate and implement a bubble curtain for a vital step in plastic collection in rivers, that is horizontal and vertical plastic concentration. An ideal flow shaping device would be resistant to high-velocity rivers’ flow and reliable in wide and deep
Plastic pollution is one of the biggest challenges today and increasing every year. 5 million tons of plastic debris end up in the ocean each year exclusively through rivers. To tackle this problem the RSL Lab (together with ALPLA) have started the Autonomous River Cleanup (ARC) project recently. The student is encouraged to join and actively participate in the ARC team.
In the last decades, different installations have been adopted to counteract the macroplastic pollution directly in oceans and, more recently, in rivers.
