This animation of axial vorticity for azimuthal Fourier modes 1, 5 and 6 helps to illustrate a triadic resonance instability mechanism for flow in a precessing, rotating cylinder of fluid (Albrecht, Blackburn, Lopez, Manasseh & Meunier 2015). The animations are seen in the frame of reference of the cylinder, in which the forcing directly driven by precessional acceleration occurs in Fourier mode 1 and rotates with the precession frequency. Theory dictates that the other two modes which directly participate in the triad must differ by 1 in azimuth (6-5=1) and counter-rotate in the cylinder frame, exactly as seen here.


An illustration of the asymptotics underlying vortex-wave interaction that results in a finite-amplitude equilibrium (a.k.a. self-sustaining) state in plane Couette flow (Blackburn, Hall & Sherwin 2013). Part of the significance here is that plane Couette flow is linearly stable (i.e. stable to infinitesimal disturbances) at all Reynolds numbers; in the linearly stable state, the streak flow is a linear function of wall-normal distance (y) with no spanwise (z) variation. However, the flow supports at nonlinear equilibrium a combination of finite-amplitude disturbances that lead to a first-order change in the basic state, and these finite-amplitude disturbances have a well-defined asymptotic dependence on Reynolds number R. A two-dimensional roll flow (a), smaller than the basic state by a factor 1/R, is enough to drive the change to a new two-dimensional flow (b), with a spanwise variation producing alternating high- and low-speed streaky disturbances near each wall. The critical layer for a non-travelling wave on this streaky flow is a contour of zero velocity, which is the green isosurface in (b). The streaky flow supports standing three-dimensional wavy disturbances (c) which decay with R-7/6 at equilibrium and which, as can be seen, cluster near the streak's critical layer. Taking the streamwise (x) average of the wavy flow produces two-dimensional Reynolds stresses that are principally significant to the small-amplitude roll flow; their divergence produces a stress jump (d) that drives the roll flow, and hence preserves the whole disturbance system at a finite amplitude. The resulting solution to the Navier–Stokes equations is also called an 'exact coherent structure'. We showed that as spanwise wave lengthscales reduce, these structures become smaller, localising near the centre of the flow, and hence become relevant to arbitrary shear flows since the direct influence of the walls is lost.


An animation of the period-doubling breakdown of pulsatile flow in an axisymmetric constricted tube (Sherwin & Blackburn 2005, Blackburn & Sherwin 2007). This is an idealised representation of blood flow in a stenotic artery with 75% occlusion, Reynolds number 400, Womersley number 15.85. The vortex rings that are blown out of the constriction with each pulse tilt slightly forward, then backward, on successive periods. Under self-induction and wall interaction of the vorticity in the ring, this tilting proceeds rapidly to an energetic breakdown.

Animation of bypass transition in pulsatile stenotic pipe flow in which the pulse waveform represents typical flow in the human common carotid artery (Mao, Sherwin & Blackburn 2010). Linear transient energy growth is extremely large, of order 1×1025 within half a pulse period for suitable intial disturbances at Reynolds number Re=300. For even a tiny seeding with the optimal initial disturbance, a puff of turbulence is generated downstream of the stenosis. This washes slowly downstream and decays during subsequent pulse cycles. Mean flow is from left to right and the stenosis is to the left of the field of view.

An animation of linear transient instability in steady stenotic flow created by an optimal inflow boundary condition (as opposed to an initial) disturbance. Colour contours of azimuthal vorticity visualised in the azimuthal semi-plane, azimuthal Fourier mode m=1. (Mao, Blackburn & Sherwin 2012).

Animation of transient two-dimensional convective instability in flow over a backward-facing step at Re=500 (Blackburn, Barkley & Sherwin 2008, Barkley, Blackburn & Sherwin 2008), visualised as contours of perturbation vorticity. The optimal disturbance initial condition is a wave packet that is very tightly clustered around the step edge, and grows into an array of counter-rotating rollers that fill the downstream channel, at a location past both (upper and lower) separation zones, before eventually decaying. The maximum two-dimensional energy growth at this Reynolds number is 63.1×103.


The flow generated by a circular cylinder moving from side to side in quiescent fluid has a number of different instability modes, depending on the amplitude and period of the motion. This image of massless particles advected by a quasi-periodic instability mode shows how small puffs form up into large-scale vortices that move away from the cylinder along the axis of oscillation (Elston, Blackburn & Sheridan, 2006).

Mode A, Re=195 Mode B, Re=265 Mode TW, Re=400
Karman-street wakes of two-dimensional bodies generically have three kinds of three-dimensional instability modes; two distinct synchronous modes which at onset have the same frequency as the underlying wake, and two related quasi-periodic modes (standing and travelling waves), one of which may be stable. Here we see in top view the two synchronous modes of the circular cylinder wake (modes A and B), and the travelling wave mode, which is the third to bifurcate from the two-dimensional basic state as Reynolds numbers are increased (Blackburn, Marques & Lopez, 2005).

t=t0 t=t0+T/2
Isosurfaces of vorticity indicating a synchronous three-dimensional instability mode of a flow in a periodically driven two-dimensional rectangular cavity (Blackburn & Lopez 2003). The cavity cross-section has a height:width ratio of 2:1, and the lower floor has an imposed sinusoidal oscillation of temporal period T. The symmetry group of the base flow is identical to that of many time-periodic wakes, and the three-dimensional instability modes consequently have the same symmetry properties as e.g. those of the circular cylinder wake. There are two control parameters, a Reynolds number and a Stokes number. Here, at St=20 and Re=535, the first mode to become unstable is a short-wavelength one, with some similarity to the cylinder wake's mode B. Translucent isosurfaces are of wall-parallel vorticity, while the solid red/yellow surfaces are of the vertical vorticity component. At other parameter values, this flow also has a long-wavelength synchronous mode and a quasi-periodic modulated travelling wave mode.

Periodic axisymmetric state, Re=3000 Rotating wave with 6-fold symmetry, Re=4000

Instabilities of the flow produced by steady rotation of the lower lid of a cylindrical cavity with height/radius ratio H/R=2.5. At low Reynolds numbers the flow is axisymetric, steady, and has an axial vortex breakdown. The flow first becomes unstable to a periodic axisymmetric instability through a Hopf bifurcation at Re=2707, but at higher Reynolds numbers rotating waves also become unstable, and are modulated by the axisymmetric pulsation. Blackburn & Lopez (2000), Blackburn (2002), Blackburn & Lopez (2002).


Colour contours of spanwise- and phase-averaged spanwise component of vorticity from a three-dimensional simulation of flow past a circular cylinder in vortex-induced vibration, at Re=720, Vr=6.5 (Blackburn, Govardhan & Williamson 2001). The four frames illustrate averages for phase-points equispaced over the average vortex-shedding period. Note the clear indication of 2P-mode shedding, the first time this had been documented as a phase-averaged result in a DNS study. The average oscillation amplitude was approximately 0.45D. Download an MPEG movie from the simulation (6.4MB).


The pattern produced by tracking massless particles in two-dimensional flow past a swimming cylinder (Blackburn, Elston & Sheridan 1999). The cylinder has forced oscillations both in the vertical direction and in rotation about its axis. The time-average effect is to create a low pressure region to the left of the cylinder; if the cylinder is free to move horizontally, it 'swims' to the left, leaving behind it a sequence of puff-like structures, seen here.

As one stage in the 'dynamic' procedure for large-eddy simulation, velocity fields need explicit smoothing, or spatial low-pass filtering, to remove fine-scale fluctuations. These panels show contours of streamwise velocity component on a slice through a spectral element simulation of a turbulent channel flow, both before filtering, and after a filter was applied in the Legendre polynomial space projection of the data in each element (Blackburn & Schmidt 2003).


A perspective side-view of near-wall structures in a turbulent boundary layer, visualised with an instantaneous isosurface of a positive value of the discriminant of the velocity gradient tensor (Blackburn, Mansour & Cantwell 1996). When the discriminant is positive, the velocity gradient tensor has a pair of complex-conjugate eigenvalues and a single real eigenvalue, so the local fluid motion has a spiralling character. The isosurfaces mark a a large number of distinct structures that are nearly parallel to the wall in the buffer layer, which, further from the wall, tilt to have an orientation closer to 45o downstream, i.e. aligned with the direction of time-average maximum strain rate. The time-mean flow direction is indicated by the arrow.
