Passive control of backstep flow

Experimental Thermal and Fluid Science, 1998
Abstract The passive control of turbulent flow downstream of a backward-facing step using a permeable reattachment surface is described. An impermeable reattachment surface leads to the upstream convection of rotational fluid and pressure disturbances which is absent when a permeable surface is used.

Blade Design with Passive Flow Control Technologies

2020
This chapter focuses on the application of passive flow control technologies to wind turbine blades. The motivation of using these technologies is always an enhancement of the wind turbine performance (increase of power production, load reduction, noise reduction, etc.) in comparison to the standard blade.

Passive Control of Transonic Cavity Flow

Journal of Fluids Engineering, 2008
Abstract Open cavities at transonic speeds can result in acoustic resonant flow behavior with fluctuating pressure levels of sufficient intensity to cause significant damage to internal stores and surrounding structures. Extensive research in this field has produced numerous cavity flow control techniques, the more effective of which may

Flow Seperation and Passive Flow Control on E387 Airfoil

54th AIAA Aerospace Sciences Meeting, 2016
The behavior of a MVG vane at three different design angles was simulated with LES on an Eppler e387 airfoil that was suffering flow separation. The e387 airfoil was placed at an angle of attack of 12 degrees and at Reynolds number of 200,000 based on the chord length. Different parameters of the generated vortex from the MVG were analyzed to study the

Passive flow control of bileaflet mechanical heart valve leakage flow

Journal of Biomechanics, 2008
Blood damage and platelet activation are inherent problems with present day mechanical heart valve designs. We investigate the approach of passive flow control applied to bileaflet mechanical heart valve (BMHV) flows as a means of optimizing leakage flow hemodynamics at length scales relevant to blood damage and platelet activation.
