Haven't seen much here lately? That's because updates from Physical Review Fluids are now shared through @APSjournals.
Thanks for following us over the years, we hope you'll join us there!

As we celebrate #PRF10, Chief editor Beverley McKeon shares reflections from her recent visits as part of the Journal's anniversary:
> In the 10th birthday year of Phys. Rev. Fluids, I was very pleased to be able to visit India and Singapore to promote the journal.
1/3
I visited and spoke at the National University of Singapore (NUS), A-STAR (public agency), the International Center for Theoretical Sciences in Bangalore (ICTS), the Indian Institute of Science (IISc) in Bangalore and the Indian Institute of Technology Bombay (IIT-B).

New simulations in Physical Review Fluids show 4D quantum vortices reconnecting in ways 3D never allows: one mode follows the classic universal scaling law, another loses almost no energy at all, and a third type doesn’t reconnect, it just spins.

ALT Six 3D renderings of a 4D quantum vortex surface at three time points, comparing two reconnection types: planar-aligned vortices (top row) and anti-aligned vortices (bottom row). Each panel shows an intersecting or reconnected vortex surface in the x-y-z subspace, with color representing position along the fourth dimension, w. Over time, both cases show a hole opening at the point where the vortices meet.
When shock waves propagate through a flexible fiber curtain, increasing the fiber aspect ratio and reducing flexibility increase shock resistance. A scaling law predicts the curtain expansion, accounting for fiber elongation and bending deformation.

A simple droplet generation technique consists of rapidly stretching a liquid ligament from static or vibrating baths. Systematic experiments map the parameter space for ligament pinch-off into a single droplet, showing excellent reproducibility.

In a circular unheated Hele-Shaw cell, self-sustaining CH4-air flames emerge spontaneously, rotating along the edge. The stable traveling-wave pattern arises from a balance between local flame speed, flow, and wall heat loss.

Simulations of stratified flows past a vertical cylinder show that weak stratification gives a narrow turbulent wake, while in strong stratification, thermocline-spanning recirculation cells and stationary internal waves appear.
Editors' suggestion: go.aps.org/4xLeCXh
Strongly gyrotactic microswimmers in turbulence align with the vertical, weakly gyrotactic ones are nearly isotropic, and rods align with the strain direction, showing how orientation and transport are set by response time and shape.
Editors' suggestion go.aps.org/4fCt7qi
Limited spatial resolution constrains our understanding of Rayleigh-Taylor mixing, but convolutional-neural-network-based superresolution reconstructs multiscale flow fields, recovering mixedness and generalizing across unseen phases and flow parameters.

A 30-day experiment follows the flow of a high-viscosity liquid through a capillary tube, revealing persistent diffusive imbibition and testing how models that account for the dynamic contact angle perform in long-term imbibition processes.

The sound emitted by a detaching bubble is set by the amplitude of its volumetric oscillations, mainly controlled by the bubble’s initial growth velocity, as shown by experiments and captured by a simple model.
Editors' suggestion: go.aps.org/4g0YiLZ
Forcing a wind-turbine wake via slow periodic rotation-rate oscillations generates traveling waves advected with the wake, controlled by thrust and tip-speed ratio, highlighting the importance of advection for modeling and control of wind-turbine wakes.
go.aps.org/4yR18e4
A passive vector model with spatially linear advection has a Hopf equation that can be solved exactly by an ensemble of Gaussian fields, displays an intermittent energy flux from large to small scales, arising from a probabilistic mixture of sub-ensembles

A sessile soap bubble in an electric field stretches into a taller dome, but past a critical point the top sharpens into a pre-jet cone. When properly rescaled, bubbles of different sizes deform along the same curve, set by electrocapillary balance.

A new framework provides quantitative guidelines to accurately simulate turbulent two-phase flows, with a priori criteria and cost estimates based on Reynolds, Weber, and Capillary numbers, capturing key interfacial scales.
Editors' suggestion: go.aps.org/4hoTgtO
The shear rate determining the viscous-to-inertial transition of non-Brownian suspensions near jamming has a critical behavior, tied to a diverging microstructural length scale governing the emergence of inertial effects.
