Wide Speed Range
*Sub-headline: * White sharks and extinct giant megalodons may swim at
similar speeds
*(Tokyo, August 6) *New findings on how sharks achieve drag reduction could
inspire the design of riblets for more efficient aircraft and boats. In
their investigation of great white shark denticles, researchers from Tokyo
Tech found that ridge height and spacing play crucial roles in drag
reduction at different swimming speeds. Higher middle ridges aid sharks in
efficient cruising at slower speeds, while the lower side ridges become
more critical for drag reduction during high-speed hunting bursts. The
analysis also suggests that the speeds of an extinct giant shark,
megalodon, may not much differ from those of the white shark.
