Strouhal number analysis for the swimming of little penguin (Eudyptula minor): Proof of efficient underwater propulsion
Penguins are the utmost specialized wing-propelled divers as their flapping action is accountable for the entire underwater propulsion.However, numerical Scrubs/Scrapers evidence of how efficient their underwater propulsion is has not been studied to date.Literature sources suggest that propulsive efficiency peaks when the Strouhal number (St) rang
