New paper in @JFluidMech today. Similar to work by Motoori & @goto_susumu (2019), we look at enstrophy production (black lines). However, interesting insights arise from expanding the equations into normal and non-normal terms (grey lines)

Contemplating a PhD at the interface between wind engineering and fluid mechanics? Perhaps consider applying to the AuraCDT for my project (with Yi Li in Sheffield and Jialin Su here in @LboroEng)

We have 2 new MSc programmes recruiting for 2026 @LboroABCE@WEDCUK. They should interest graduates wanting a career in sustainable water management and applied data analytics. @tmmrjrbnks is director for the former and me for the latter. Clear links to our @UNESCOchairIMRR.
Using the network proposed in https://t.co/2zVKnbL7L4, Maurizio and I looked for natural groupings of nodes for the Lagrangian dynamics of turbulence and found that including non-normality was key (see sketch of extended Q-R space). Out now in PhysicaD https://t.co/OLJlk78oiG
Over my time in Lyon, I have learnt that the French for "eigenvalues" is "valeurs propre". Unfortunately, therefore, "singular values" is the rather boring "valeurs singulieres". What nobody can then tell me is the French for "pseudoeigenvalues". Perhaps "pseudovaleurs propre"?
Only 20 minutes to go until I brutalise the French language in my seminar. I stopped studying French at 17 yrs and the last seminar in France was 16 years ago when I was 36. Hence, estimate of half-life appearing soon.
In our new paper in @PhysRevFluids Maurizio and I define a network for turbulence not using physical coordinates but in the space of the invariants. There are some cool new dynamics emphasised. Thanks to @LeverhulmeTrust & Michael Wilczek for support.

Academic rankings are all a bit silly, but possible retrospective vindication from https://t.co/39nuOUTG5K of my decision as an undergrad to head off to Canada for my MSc on avalanches:
In this new paper in @JFluidMech, Juan & George @aeroimperial study small scale dynamics over a NACA airfoil. Nice to see applications of some concept from my JFM(2018) in aeronautics:

In this paper, Rufus Dickinson develops a method for fluid-filament interaction modelling without the expense of FE modelling the filament (with @rand_vibration & @tmmrjrbnks); useful if your focus is on the flow: https://t.co/vrzDntbuLv
Excellent UKTC meeting @stjohnscam on Monday and Tuesday this week. A fascinating range of talks where UK HPC resources were used to underpin flow simulations. Thanks to Andy Wheeler for all the local organization and @LaizetSylvain for putting together such a great programme.
