1 Οκτ 2010 · Flow structure around a gliding flying fish. Fig. 9 shows the streamwise flow structures around a flying fish (model L 3 at four different angles of attack). At the spanwise location where pectoral and pelvic fins overlap (left column), we observed an interesting flow structure.
20 Ιουν 2022 · By taking advantage of low-pressure regions of accelerated flow behind and to the side of a cylinder, entraining fish act like drafting race cars, saving 50% of the energy that would be otherwise used during swimming in laminar flows.
11 Νοε 2007 · Fish in schools or current-swept habitats can benefit from altered flows using two distinct though not mutually exclusive mechanisms: flow refuging (exploiting regions of reduced flow relative to the earth frame of reference) and vortex capture (harnessing the energy of environmental vortices).
24 Μαρ 2016 · (a(i)) Swimming fishes minimize pressure around the head, which maximizes the ability for flow sensing. The intensity of self-generated pressures at the head (shown as a heat map) for...
Like most fish, the tilapia has a streamlined body shape reducing water resistance to movement and enabling the tilapia to cut easily through water. Its head is inflexible, which helps it maintain forward thrust. [3] Its scales overlap and point backwards, allowing water to pass over the fish without unnecessary obstruction. Water friction is ...
6 Ιαν 2015 · When a fish is pulled up, "that balloon rapidly begins to expand as the pressure from the water decreases," says Chris Lowe, a marine scientist at California State, Long Beach.
If delay lines were implemented in the fish lateral line system, flow-sensitive central units should be found, which respond exclusively to a head-to-tail flow, are tuned to a particular bulk flow velocity, and are insensitive to flow fluctuations.
