📢 PRFluids Editors' suggestion: Inspired by swimming animals that undulate to propel themselves in water, Fu et al. use a biomimetic robotic swimmer to find optimal control strategies for maximizing underwater thrust via reinforcement learning Read more @ go.aps.org/42Hk9kS

📢PRFluids Editors’ suggestion: Using simulations and stability analysis, Hildebrand et al. study the effect of a forward-facing step on disturbance amplification in a flat-plate boundary layer, relevant for reducing aviation's environmental impact. 🔗go.aps.org/3EmIK5e

The first SCOAP3 assessment of open science practices gave our journals high marks. A review of @PhysRevLetters, Physical Review C, and Physical Review D earned nearly double the total score of the next-highest publisher, showing our commitment to #OpenScience. Learn more:

Grandoni et al adapt an interferometric laser imaging method to measure droplet size and velocity simultaneously, with application to droplets produced by speaking and coughing. Their work appears as an Editors Suggestion: go.aps.org/4jjuNnY

Shrimp swim by paddling 5 pairs of appendages. Using simulations, Lou et al show how they move to minimize drag. Check out their recently published paper here: go.aps.org/4jF8F79 #FluidDynamics #Biofluids

Stefan Domino will present the results of his recently accepted paper on fire-engulfed objects in a crosswind during the upcoming PR Fluids Journal Club on May 1 (8am PDT, 11am EDT, 4pm GMT+1). Register at go.aps.org/4jKPOHV to hear about his state-of-the-art LES approach.

📢 PRFluids Editors' suggestion: In a vertical diamond formation, fish schools can exploit complex hydrodynamic interactions to boost swimming performance 🐠 Read the full paper by Menzer et al. @ go.aps.org/4iAJwJQ, also featured in Physics Magazine go.aps.org/3YhYbT6

Extreme events in turbulence are more universal than expected! In their new Letter, Buaria & Pumir combine simulations and experiments across turbulent flows to show that the extreme velocity gradients behave universally—key for theory and modeling 🔗 go.aps.org/3YhxQ7J

🗓️✏️ From the April issue (1) go.aps.org/4314L21 (2) go.aps.org/3RJMb9i (3) go.aps.org/3EJryXY (4) go.aps.org/4cXPtiN Have a look at the full issue from the last month here go.aps.org/4jSpj3m #fluiddynamics

In microfluidic networks, flow oscillations and chaos can emerge even without external modulation or deformable structures. Adilson E. Motter and colleagues show that fluid inertia drives the responsible mechanism, expanding on-chip flow control design. 🔗 go.aps.org/4iQkeYx

📢 PRFluids Editors' suggestion: How does oil get trapped in microscale pores during water invasion? McBride et al. show that higher oil viscosity and water speed cause more trapping, due to a transition from meniscus displacement to viscous fingering. 🔗 go.aps.org/4lXHp61

In offshore wind farms, wind-wave interactions significantly affect performance. Santoni et al. use large-eddy simulations and compare two boundary conditions, highlighting the need for realistic sea surface interactions in accurate wind farm modeling. 🔗 go.aps.org/4m2byBf

📢PRFluids Editors' suggestion: How do water droplets form and evolve after vapor condenses on a surface? Using asymptotic matching, Bouillant et al. show that after nucleation, drop count stabilizes due to collective effects mediated by vapor diffusion 🔗 go.aps.org/43hcf0T

Did you know heavy rainfall can spread disease among plant leaves — turning them into catapults that launch spore-filled water droplets into the leaves above. 🌧️ 🦠 A new study in Physical Review Fluids details the #physics behind the spread: go.aps.org/4jWDmoy

Evaporating Leidenfrost droplets can spontaneously bounce like on a trampoline. Agrawal et al. show this intermittent behavior stems from a resonance driven by vapor-layer oscillations and droplet vibrations, regardless of liquid and surface conditions. 🔗 go.aps.org/4kejvBp

Is ice always covered by a thin water layer? Demmenie et al. show that near melting, the contact angle of a water droplet on ice plateaus at 12°. The result is explained by surface energy, not crystallization, indicating that ice is never fully wetted. 🔗 go.aps.org/4kiNVlU

How does small-scale bottom topography affect transport in the oceanic boundary layer? Using Large Eddy Simulations, Cuadras et al. show that small seabed features can enhance transport by up to 30%, highlighting the importance of flow separation. 🔗 go.aps.org/4mezYY6

📢 PRFluids Editors' suggestion: in vortical flows at high magnetic Reynolds numbers, weak magnetic fields can affect flow dynamics. Via 2D incompressible MHD simulations, Tessier et al. vary the magnetic field strength and identify 4 dynamical regimes 🔗 go.aps.org/3SeGiBe

📢 PRFluids Editors' suggestion: Convection driven by buoyancy released during moisture condensation is common in the atmosphere. Dorel et al. present a lab experiment replicating key features of moist convection and study the instabilities that develop 🔗 go.aps.org/3Fm5XVS
