Oodl.ai vs ViscousJoukowski

Oodl is a personal museum in your pocket — the effortless swipe of social media, but every page is a masterpiece. THE FEED, REIMAGINED Swipe up for the next work. Swipe sideways to change wings. Over a hundred thousand open-access artworks stream live from The Metropolitan Museum of Art, the Art Institute of Chicago, the Cleveland Museum of Art, and SMK — the National Gallery of Denmark. Full screen, no ads, no comments, no account. nOODL WHAT MOVES YOU Double-tap to nOodl (save) a work. Your saves build a private collection, teach the on-device blend your taste — more of the eras, mediums, and artists you respond to — and grow into a living map of your eye: a floating bubble portrait of your taste, stirred by the tilt of your phone. YOUR PHOTOS, ON THE SAME WALL Create private galleries from your photos and videos, or subscribe to a Photos album — including iCloud Shared Albums — and it becomes a channel that updates automatically as you add photos on any device. Videos loop full-screen like reels. Everything flows into your All feed alongside the museums. Oodl filters screenshots and near-duplicates on-device and surfaces your best shots. Double-tap your own photo to give it a title. LEARN THE STORY Tap "learn" on any piece for a personal art-magazine page: the subjects in the image (identified entirely on your iPhone), encyclopedia context on the artist, the work, and the place a photo was taken, and — on iPhones with Apple Intelligence — a short curator's note written on-device. In focus mode, pinch into the brushwork and let Apple's Visual Look Up identify what you're seeing. RIGHTS DONE RIGHT Every artwork carries its license (CC0 / Public Domain), museum credit line, and a link back to the source. Your own media is marked private and never leaves your device. FREE MEANS FREE No subscription, no ads, no tracking, no account. The world's museums opened their collections to everyone — Oodl is their home on your phone.

Are you interested in fluid dynamics? Viscous Joukowski simulates the flow around a Joukowski airfoil by solving the two-dimensional incompressible Navier–Stokes equations directly on your device. For teachers, students, and curious aerodynamicists, it provides an interactive way to explore how viscosity changes lift, drag, pressure, boundary layers, separation, and wake formation. Watch vorticity, speed, pressure, and streamlines evolve around the airfoil. Change the angle of attack, thickness, and camber by dragging directly on the flow field, or use precision controls. Adjust the Reynolds number to explore steady flow, separated wakes, starting vortices, and vortex shedding. Surface-pressure curves and aerodynamic-force estimates update as the simulation develops. The app also includes the classical analytical Joukowski potential-flow solution. Overlay it on the computed viscous pressure distribution to see where the ideal textbook model agrees with—or departs from—the Navier–Stokes result. In the potential solution, circulation is selected using the Kutta condition; in the viscous simulation, circulation and the wake develop dynamically from the no-slip flow. All calculations run locally using Apple MLX and GPU-accelerated Fourier methods. No server, account, or cloud computation is required.
