In turbulent superfluid helium, quantum vortex lines form tangles with a characteristic mean intervortex spacing. Experiments show this spacing follows a Kolmogorov-like power law with Reynolds number, which can be explained by classical turbulence theory. https://t.co/TkEDPH5VQx

While traditional wave models often struggle to efficiently capture ocean waves nonlinearity, a new physics-informed neural network approach pushes this limit. From sparse data, it reconstructs and predicts phase-resolved, nonlinear, and dispersive waves. https://t.co/6etXwmbyzd

🚨 Don’t miss the Gallery of Fluid Motion Submission Deadline - Sept. 16 at 5:00 pm ET! DFD Members are invited to share their remarkable works as videos and posters, highlighting the captivating science and breathtaking beauty of fluid motion!

To bloom, phytoplankton must cross stratified shear layers. Simulations show that different types of instability affect scalar fluxes and mixing, accelerating phytoplankton growth, especially when physical and biological timescales match. Read more at https://t.co/NvcbEBHZNL

Why do Lagrangian particles in turbulence separate faster backward in time than forward? In a new Letter, @ronshnapp shows this irreversibility is driven by how the particles' velocities align with the separation vector, rather than their speed. https://t.co/PA00hJFAS4

The excitation of multiple modes in the shape oscillations of an air bubble in water resulting from coalescence can be probed using magnetic levitation. While the bubble shape agrees with theory, multimode coupling greatly affects its frequency response. https://t.co/zifaCN0FAO

A splitter plate on the windward side of a cylinder can amplify, rather than suppress, rotational vibrations. Simulations by @ak_pandey94 & @R_Bhardwaj_IITB at low Reynolds numbers show regimes from vortex-driven large-amplitude oscillations to chaos. 🔗 https://t.co/YYQuj2NSr5

From microalgae to mouse embryos, cilia perform vital roles: swimming, feeding, pumping, and sensing. This invited article explores how cilia generate flow, highlighting their diverse functions and the valuable insights fluid dynamics can offer to biology. https://t.co/Ryb41uVSHJ

Temporal resolution of turbulent flow fields can be enhanced with a new model-based approach: projecting the Navier-Stokes equations onto a low-dimensional POD space and integrating them in time enables reconstruction of flow dynamics from sparse PIV data. https://t.co/qLBt8SwdB5

📢 PRFluids Editors' suggestion: When coughing or sneezing, mucus forms bag-like structures that break into droplets. Experiments and simulations show that viscoelasticity makes these bags larger and thinner, which reduces the droplet size upon rupture. https://t.co/a1e9ZQTTzM

📢 PRFluids Editors' Suggestion: To navigate upwind, boats zigzag to flip the sail into its mirror shape. Simulations use a membrane and a vortex-sheet model to study which parameters cause a successful flip 🔗 https://t.co/SYdeOPLcpD Synopsis in Physics: https://t.co/BGMwBEBrID

☁️ How does turbulent mixing affect cloud entrainment? Using the Lagrangian diffuselet model to study passive scalar mixing in a cloudy air filament, with and without phase change, shows good agreement with simulations in the early stages of the process. https://t.co/3SerenfB06

🚨 The PRFluids Journal Club returns on July 29th at 12:00 PM Eastern Time! This time, Valentin Dorel and colleagues will present their recent paper “Laboratory Modeling of Moist Convection Using a Reactive Fluid”, followed by a live Q&A. Register here:

Those interested should contact the APS-DFD Chair of the Media and Science Relations Committee: Karen Mulleners (karen.mulleners@epfl.ch) or the outgoing previous social media officer: Sarah Morris (sarah.morris14@montana.edu).

This is a great opportunity to get to know - and be known by - the global Fluid Dynamics community! The selected officer(s) will take care of gathering content and posting regularly, and they will be supervised by the Media & Science Relations committee of the APS -DFD.

Seeking the next APS-DFD social media officer! 🎉 The American Physics Society (APS) Division of Fluid Dynamics (DFD) is currently looking for motivated junior APS-DFD members to become the next APS-DFD social media officer for a two-year term.

📢 PRFluids Editors' suggestion: When a beet slice sits in its own juice, a clear fringe appears. Liu et al. trace it to a surface dimple caused by wetting-induced suction at the beet’s edge, set by the balance of surface tension, gravity and viscosity. 🔗 https://t.co/QI0gU6eOJ9
