The results of the study were obtained used the ARCHIE-WeST High Performance Computer based at the University of Strathclyde. a water-train, to transport more cargoes without extra fuel cost. These principles could be potentially applied to design modern freight carrying vessels, e.g. Our calculations provide new insights into the mechanisms of formation swimming. "This study is the first to reveal the reasons why the formation movement of waterfowl can preserve individuals' energy expenditure. Zhiming Yuan, senior lecturer in the Department of Naval Architecture, Ocean & Marine Engineering, who led the study, said: "Wave riding and wave passing are probably the principal reasons for the evolution of swimming formation by waterfowl. Each individual under that equilibrium acts as a wave passer, passing the waves' energy to its trailing companion without any energy losses.ĭr.

Starting from the third duckling the wave drag of individuals gradually tends towards zero, and a delicate dynamic equilibrium is achieved. Interestingly this wave-riding benefit appears to be passed down to the rest of the ducklings in the line formation. This causes the wave drag of the duckling to turn positive meaning the baby bird is actually pushed forward by the wave. Using a mathematical and numerical model, the researchers found that when a duckling swims at a 'sweet point' behind its mother a 'destructive wave interference phenomenon' occurs. In a research paper published in the Journal of Fluid Mechanics, naval architecture experts conclude that ducklings benefit from 'wave riding' and 'wave passing." But just why do they swim in that formation? Scientists at the University of Strathclyde believe they have discovered the reason-which could have applications in maritime shipping too.
