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.

Crystallization and Motility-Induced Phase Separation in the Flow of Active Brownian Particles Around an Obstacle [PDF]

EPJ Web of Conferences
The interaction between fluid flow and obstacles is a fundamental problem in fluid dynamics, exemplified by the Kármán vortex street and its Reynolds number-dependent instabilities.

Vortex shedding from a blunt trailing edge with equal and unequal external mean velocities [PDF]

A flow visualization study showed that strong Karman vortices are developed behind the blunt trailing edge of a plate when the free stream velocities over both surfaces are equal.

A Model for the Voltage Steps in the Breakdown of the Integer Quantum Hall Effect

, 2003
In samples used to maintain the US resistance standard the breakdown of the dissipationless integer quantum Hall effect occurs as a series of dissipative voltage steps.

On the analogy between streamlined magnetic and solid obstacles

, 2009
Analogies are elaborated in the qualitative description of two systems: the magnetohydrodynamic (MHD) flow moving through a region where an external local magnetic field (magnetic obstacle) is applied, and the ordinary hydrodynamic flow around a solid ...

Effect of the Wake of the Transducer Supports on the Ultrasonic Anemometer Measurements [PDF]

, 2012
The wake produced by the structural supports of the ultrasonic anemometers (UAs)causes distortions in the velocity field in the vicinity of the sonic path.

Vortex-Breakdown Efficiency of Planar Regular Grid Structures—Towards the Development of Design Guidelines

Fluids
The work presented here aims to provide design guidelines to create vortex-damping structures. A design of experiment was developed to investigate the individual and combined effects of the geometrical properties of planar regular grid structures, i.e ...

Wall turbulence control [PDF]

A variety of wall turbulence control devices which were experimentally investigated are discussed; these include devices for burst control, alteration of outer flow structures, large eddy substitution, increased heat transfer efficiency, and reduction of

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 ...

Problems in fluid dynamics [PDF]

A scheme was developed for the parametric differentiation and integration of gas dynamics equations. A numerical integration of the gas dynamics equations is necessarily performed for a specific set of parameter values.
