APS Division of Fluid Dynamics

📢 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 🔗 go.aps.org/4eW4bbj Synopsis in Physics: go.aps.org/4lYaE7E

☁️ 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. go.aps.org/4nK8D0G

🚨 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: go.aps.org/3IzBnsS

🗓️ From the June issue (1) go.aps.org/4lyNTqX (2) go.aps.org/3I96mMj (3) go.aps.org/44HMFE3 (4) go.aps.org/4lznPfo Find these and all other papers published in Phys. Rev. Fluids over the past month at go.aps.org/4lBifcs #fluiddynamics

📢 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. 🔗 go.aps.org/4nkPSAR

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 (go.aps.org/4iAJwJQ). Register here: go.aps.org/440qvLQ

Submit your abstract for one of the world’s largest conferences in #FluidDynamics and share your research with 3,500 colleagues at the annual meeting of the Division of Fluid Dynamics. Abstracts close July 25. 🔗 go.aps.org/3FBYWjL

🗓️✏️ 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_motter and colleagues show that fluid inertia drives the responsible mechanism, expanding on-chip flow control design. 🔗 go.aps.org/4iQkeYx

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

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 @PhysRevFluids 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

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: 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

📢 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
