Take a look back at some of the outstanding papers published in PR Fluids in 2024 as well highlights from our Journal Club, the APS DFD award-winning posters and videos, and Frenkiel Award winners. (Music from #Uppbeat : License code: POH6OBESMHQOEGJP)

In Leidenfrost rings, rotating and regular polygonal patterns appear spontaneously. A new model incorporating surface tension, vortices, and buoyancy-driven thermocapillary flows explains the experimental observations through cnoidal wave solutions. 🔗

Linear analysis is a powerful tool for understanding and predicting coherent structures in wall-bounded turbulence. Introducing an eddy-viscosity-based white-noise stochastic forcing improves its predictive capabilities across Reynolds numbers!.Read more @

📢 PRFluids Editors' suggestion: In light winds, windsurfing athletes pump the sail to generate propulsion and keep the board afloat. Sport-mimetic experiments study how pitching motions affect forces and performance, exploring sailing race strategies. 🔗

In acoustofluidic simulations, zero Lagrangian and zero mass transport velocity boundary conditions are not equivalent! A new solver including spatial density variations and boundary conditions offers a framework for studying acoustofluidic phenomena. 🔗

A charge-neutral drop in a uniform DC electric field doesn’t migrate in free space. But place an insulating wall nearby, parallel to the field, and the drop will be laterally attracted or repelled, as shown by Sen, Firouznia, et al. Read more at

Solute transport in porous media is often modeled with constant dispersivity, but is this valid for shear-thinning fluids? Al-Qenae et al. show that the viscosity varies across pore spaces, enhancing dispersion, and present a model that accounts for it.🔗

Marine larvae must settle in flows much faster than their swimming speed. Gysbers, @mark_levenstein & Juarez show that certain substrate topographies create recirculatory flows that favour settlement, helping larvae reach suitable habitats efficiently. 🔗

📢 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. 🔗

📢 PRFluids Editors' suggestion: In debris flows, Meng et al. study the onset of roll waves and their subsequent coarsening, explaining field measurements in Switzerland. Read the paper at ,.also featured in @PhysicsMagazine @

The breakup of a stretched fluid bridge creates satellite droplets with highly reproducible sizes. Frishman & Lecoanet show the size follows a simple formula depending only on the bridge’s volume and Weber number, tied to a universal dynamical solution. 🔗

What are the benefits for individuals or groups in fish schooling? Wälchli et al. use inverse reinforcement learning to infer goals in collective systems from motion data without specifying them a priori, opening paths for bioinspired optimization. 🔗

📢 PRFluids Editors' suggestion: A metal disk on the water surface can be kept afloat by a water jet impacting it from above. Turczynowicz et al. show that the water displaced by the jet results in an increased buoyancy force that balances gravity. 🔗

Immiscible fluid interfaces destabilize during invasion in porous media. Brodin et al. use 3D imaging to show that, depending on flow rate, the interface transitions from stable sheets to unstable fingers, bridging 2D theory with complex 3D behavior. 🔗

The next PR Fluids Journal Club will take place on Thursday June 26 at 11am Eastern Time, featuring Alex Menzer and colleagues discussing their paper on the efficient hydrodynamics of schooling fish (. Register here:

📢 PRFluids Editors' suggestion: Violent eruptions of thin boundary layers may explain the observed persistent drag at high Reynolds numbers. Eyink & Quan argue these extreme wall events could break the "weak-strong uniqueness" in the Euler equations. 🔗

In a frame moving along the turbulent-nonturbulent interface of a jet flow, Lagrangian coherent structures can be detected. Khojasteh et al. identify structures associated with advection and diffusion, and study transport at the turbulent interface. 🔗

Many-body hydrodynamic interactions affect the dynamics of fluid suspensions, but measuring them experimentally is difficult. Kim, Nagella et al. present an optical tweezer-based method to quantify translation-rotation coupling between trapped colloids. 🔗
