Optimal sensing for fish school identification
, 2019 Fish schooling implies an awareness of the swimmers for their companions. In flow mediated environments, in addition to visual cues, pressure and shear sensors on the fish body are critical for providing quantitative information that assists the ...

Cylinders with Square Cross Section: Paths to Turbulence with Various Angles of Incidence [PDF]
, 2007 The path to turbulence in the wake of cylinders with square crosssection is investigated by means of direct numerical simulation, employing a two-dimensional spectral element method and Floquet linear stability analysis.

SWIMMING AGAINST THE FLOW: A ROBOTICS SIMULATION FRAMEWORK
Investigación & Desarrollo, 2016 Fish in nature take advantage of some types of turbulence and even generate it to swim with a minimum expenditure of energy. This is the case observed in rainbow trout swimming against the flow in well patterned turbulence phenomenon called Karman Street.

Vortex Dynamics Effects on the Development of a Confined Turbulent Wake
FluidsIn the present work, the turbulent wake of a circular cylinder in a confined flow environment at a blockage ratio of 14% is experimentally investigated in a wind tunnel consisting of a parallel test section followed by a constant-area distorting duct ...

Secondary flows and heat transfer in shallow flow around a cylinder: LES, PIV
EPJ Web of Conferences, 2019 We report on Large-eddy simulations (LES) of flow around a short cylinder mounted in a narrow plane channel in a range of Reynolds numbers 1000, 2000, 3750 based on the bulk velocity of the flow and diameter of the cylinder supplemented with Particle ...
