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) doi.org/10.1017/jfm.20…

Well done Finn: scoring on debut

@Saracens Well done Finny!

I never in my wildest dreams imagined Russell Crowe explaining test cricket to an American who has no idea about the game. Absolutely priceless!

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) auracdt.hull.ac.uk/research-proje…

Stage 20 #TDF2026 looks like one where all the riders can sit back and relax.

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 dx.doi.org/10.1103/PhysRe…, 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 doi.org/10.1016/j.phys…

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"?

@icelandcricket Great to see the Islensk Premier League just name-checked in the @guerillacricket coverage of the England-WIndies ODI.

The points table after day 1 of 15 in the ÍPL 2025.

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. doi.org/10.1103/PhysRe…

@goto_fmlab Your forthcoming paper in PRF on the Lagrangian inertial regime looks really interesting. Please let me know when it is out.

後藤先生も「乱流中の液滴分裂」に関する発表をしました。 研究員の渡邊さんも「回転容器内における界面を伴う流れ」に関する発表を金曜日に行います。

Academic rankings are all a bit silly, but possible retrospective vindication from scholargps.com 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: dx.doi.org/10.1017/jfm.20…

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: doi.org/10.1016/j.jflu…

@AbbasKhayyer Wow, amazing you have that photo! It was a great presentation - really interesting and provoked a lot of ideas.

Thank you so much Chris. Takafumi will be certainly happy to meet you. We will be delighted and honoured to discuss research ideas with you. I still remember your precise and insightful comment during my seminar at Sheffield in 2017 regarding projection-based SPH (below is a picture of that moment).

Congratulations to my former PhD student and current colleague, Dr Takafumi Gotoh, for being awarded a PhD degree from Kyoto University. Takafumi will pursue his academic journey as a postdoctoral research fellow at the University of Cambridge continuing to develop advanced multi-physics computational methods in the context of SPH. Takafumi first-authored and co-authored four international journal articles during his three-year-PhD study and received several awards including the Best Paper Award of SPHERIC Zhuhai 2024 for a paper, the extended version of which has been published in Computational Mechanics recently link.springer.com/article/10.100… . I wish Takafumi continued success and even greater achievements.

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.
