Linear feedback control of bluff body wakes
In this project, linear feedback control is used to modify the dynamics of fluid flows. We focus on two system identification and controller design strategies that target separated wakes behind bluff bodies. In particular, we aim to reduce the form drag and suppress the large fluctuations that typically develop in such wakes and are detrimental to efficiency and safety in a large number of indu...
متن کاملEffect of shear-layer thickness on the Strouhal–Reynolds number relationship for bluff-body wakes
In a previous paper, we provided a rationale for the empirically observed St–Re number relationship for vortex shedding in bluff-body wakes. This rationale derives from a mechanism of vortex formation observed in numerical simulations coupled with an estimate of the terms in the vorticity transport equation based on this mechanism. Adopting the typical size of the body D as the characteristic l...
متن کاملTime-mean description of turbulent bluff-body separation in the high-Reynolds-number limit
A most reliable prediction of the position of time-mean gross separation of in-compressible turbulent boundary layer (BL) flow from the smooth impervious surface of a rigid and more-or-less blunt body not only still defies theoreti-cians but, needless to say, is also of great interest from an engineering point of view. The undeniable vital progress in computational techniques made in the recent...
متن کاملReynolds number effects in stratified turbulent wakes
We report large-eddy simulations of the turbulent wake of a towed-sphere of diameter D at speed U in a linearly stratified Boussinesq fluid with buoyancy frequency N . These simulations are performed using a spectral-multidomain-penalty-method-based incompressible Navier-Stokes solver for Re ≡ UD/ν ∈ {5 × 10, 10, 4 × 10} and Fr ≡ 2U/(ND) ∈ {4, 16, 64}. Increasingly richer turbulent fine structu...
متن کاملSuboptimal feedback control of vortex shedding at low Reynolds numbers
The objective of this study is to develop a method of controlling vortex shedding behind a bluff body using control theory. A suboptimal feedback control procedure for local sensing and local actuation is developed and applied to the flow behind a circular cylinder. The location of sensors for feedback is limited to the cylinder surface and the control input from actuators is the blowing and su...
