Complete eddy self-similarity in turbulent pipe flow
Leo Hellström, Tyler Van Buren, John Vaccaro +1
For wall-bounded turbulent flows, Townsend's attached eddy hypothesis proposes that the logarithmic layer is populated by a set of energetic and geometrically self-similar eddies.…
Large-amplitude oscillations of foils for efficient propulsion
Daniel Floryan, Tyler Van Buren, Alexander J. Smits
Large-amplitude oscillations of foils have been observed to yield greater propulsive efficiency than small-amplitude oscillations. Using scaling relations and experiments on foils…
Swimmers' wake structures are not reliable indicators of swimming performance
Daniel Floryan, Tyler Van Buren, Alexander J. Smits
The structure of swimmers' wakes is often assumed to be an indicator of swimming performance, that is, how momentum is produced and energy is consumed. Here, we discuss three cases…
Roughness effects in laminar pipe flow
Utku Senturk, Alexander J. Smits
The impact of wall roughness on fully developed laminar pipe flow is investigated numerically. The roughness is comprised of square bars of varying size and pitch. Results show tha…
Efficient cruising for swimming and flying animals is dictated by fluid drag
Daniel Floryan, Tyler Van Buren, Alexander J. Smits
Many swimming and flying animals are observed to cruise in a narrow range of Strouhal numbers, where the Strouhal number is a dimensionless parameter that relates st…
