In our @BMFTR_Bund funded project #iCFD4NS we evaluate the performance of advanced mixed LES models for polydisperse two-phase flows. Combining functional & structural models improves flow statistics, such as the gas volume distribution. #OpenAccess paper: doi.org/10.1016/j.ijmu…

Lower water pressure over the surface of a propellor enough and it will boil, creating a bubble cloud: Cavitation. The bubbles then implode with a vengeance, at a speed & ferocity that erodes metal, creates light and kills. I've made a paywalled article free for you today...
🌀Just out in @NatMachIntell: Can generative AI enhance fluid simulations? We explore how diffusion models enable fast, interpretable, stochastic flow modelling, reshaping the simulation pipeline. 📝 With Luca Guastoni 🔗 nature.com/articles/s4225… #FluidMech #AI #DiffusionModels
Airfoil Digitizer is a software that I wrote a few years ago. It can selectively turn any picture into a double valued function, aka, airfoil coordinates 😀 It's not #AI. It's mathematics, as is any respectable #airfoil shape. Learn more 👉 hanleyinnovations.com/airfoildigitiz…
🆕 Paper accepted in Int. J. Heat Fluid Flow! We use DRL to control flow separation in a NACA0012 airfoil, achieving: ✅ 44% drag reduction ✅ 58.6% efficiency boost DRL outperforms periodic & fixed strategies! With @BSC_CNS ! 👉arxiv.org/abs/2502.16993 #CFD #DRL #AI #FlowControl
📢 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. 🔗 go.aps.org/3ZvCBev
Today, I plan to enjoy talking about how fun it is to hyperbolize diffusion and viscous terms. I hope the audience will enjoy it, too. --- It's going to be similar to the 64th NIA CFD seminar, which you can find at researchgate.net/publication/35….
A thrust reverser is a mechanical system used in aircraft engines to help slow down the aircraft after landing. It temporarily redirects the engine’s thrust forward, instead of backward, to reduce the plane’s speed more quickly and relieve stress on the wheel brakes. How It…
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. 🔗 go.aps.org/4ekidTX
There's an interesting paper about flapping wing ornithopter: "Kinematic and Aerodynamic Modelling of Flapping Wing Ornithopter" researchgate.net/publication/25…. I've seen their paper at an AIAA conference.

New Directions in Race Car Aerodynamics, designing for speed by Joseph Katz.
Looks like I have an account at GitHub, and used it just for once in the past. --- BTW, that's an illustration of my family name, 西川 (Nishikawa).
