Hydrodynamic

I've been watching saba stream and I couldn't find... a usable line for the Senko-Saba Animation so im just making this meme to save my sanityshow more

So apparently this shondo model is too high quality... and made me pc so laggy Thought it was over but all I have to do is turn on the simplify yayshow more

even though I was busy, I still manage to... find some spare time to learn more about toon shading for blender I found 3 of kind so farshow more

Anyways here's what I was talking about - Recently... I got myself a rebocap which can be use as mocap as well - I tried sourceio and import senko into blender - then I do a little of this and that to see if it worked And this is the result Do you see the VISION?????show more

"But where's the flash?" Watch this CNN demonstration of... 6g of PETN being ignited by open flame. What happens? The PETN burns with a visible flame for several seconds. Then it detonates. The detonation happens so fast there is no visible flash — the camera goes straight from fire to debris field. And here's the key: the fire that WAS there is blown OUT by the blast wave. This is not a shaped charge. This is unconfined PETN in open air. No flash. No fireball. The blast wave actually extinguishes the existing flame. Why? Three reasons: PETN's reaction zone is measured in microns and completes in nanoseconds (Anderson et al., Propellants Explosives Pyrotechnics, 2022). At gram scale, the entire detonation event is over in single-digit microseconds. A 30fps camera captures 33,000 μs per frame. The event occupies <0.03% of one frame. The visible "flash" people expect from explosions comes from compression-heating of surrounding air — not the explosive itself. At gram scale there simply isn't enough gas volume being heated to produce visible light that registers on a standard camera. In a shaped charge, it's even less visible because the energy is directed INTO the target as a hydrodynamic metal jet (Munroe effect), not radiated outward as heat and light. The Hezbollah pager attacks (Sept 2024) used 3-6g PETN per device. Watch the CCTV footage — no fireballs. Just a pop and casualties. Sandia National Labs detonates ~32mg PETN and researchers stand next to the chamber in safety glasses. No flash. No fire. "No flash = no explosive" is a Hollywood education, not a physics one.

This looks like a simple transparent shock absorber filled... with oil. But what you are seeing is one of the most destructive phenomena in fluid engineering. This is cavitation in its true form. The white cloud forming beneath the piston is not foam and it is not air. The oil is literally changing from liquid to vapour at room temperature. When the piston moves rapidly, the oil is forced through tiny passages inside the damper. The fluid velocity increases, the local pressure drops, and if it falls below the oil's vapour pressure, the liquid begins to boil without any increase in temperature. The moment the pressure recovers, those microscopic vapour bubbles collapse almost instantly. And that is where the real damage begins. The destructive forces of cavitation is really not understood well by most. A collapsing cavitation bubble creates shockwaves and high-speed microjets that strike nearby surfaces with enormous local forces. Repeated millions of times, these tiny implosions can slowly eat away hardened metals, destroy precision components and reduce the lifespan of expensive machinery across industries. This same invisible phenomenon is one of the biggest challenges in naval engineering. Ship propellers operating under enormous loads can suffer cavitation erosion, losing efficiency while creating underwater noise. For advanced stealth submarines, that noise can become a major problem because cavitation can reveal their position. Decades of research have gone into specialised propeller designs, pump-jets, surface finishes and hydrodynamic optimisation to delay its formation. The same issues affects hydroelectric turbines that convert the energy of entire rivers into electricity, and industrial pumps that move oil, chemicals and water through critical infrastructure around the world. Perhaps the most remarkable part is that after 4-5 decades of advances in metallurgy, coatings and manufacturing, engineers still cannot simply build a material that is immune to cavitation. The solution is not to make stronger metals forever. It is to understand the fluid dynamics so precisely that cavitation is prevented before in those destructive bubbles ever form.show more

I see the protests in France are trending. Since... I just spent 10 days there during the heart of them, I figured I'd chime in with what's actually going on. The news and clickbait accounts on X will show you the outlier events: burning buildings, raging violence and everything that triggers you. I was in the heart of Aix en Provence during the biggest protest day and filmed the center where it was happening. (See below) This is right the University, across from the church, dead center of town. The students are dancing, singing, kicking soccer balls and have comically barricaded the entrance doors to force the school to close. I visited many cities in France during the protest period, and saw zero violence or malpractice of any kind. More broadly, I spent more than a month this year in France across 3 trips and 10+ cities, including Paris, Bordeaux, Aix en Provence, Nice, Antibes, Biarritz, and others, and it's incredibly safe, charming, peaceful and beautiful. Every city I visited is nicer than almost every American city, and there's zero comparison. So much that it wouldn't even be insulting to France to try, because nobody who has spent significant time in both countries would take this comparison seriously. I spoke with the students at length about their views. I also spoke with waiters, drivers, merchants, staff and whoever. They were all civil, well articulated and genuinely wanted to see change. We can disagree about their reasoning, logic or whatever, and it's true that France has fiscal problems, but to chalk up the France protests to raging extremist violence from "pick your favorite group to blame", is a laughable misrepresentation of what's actually going on. If you exclusively watch the news and believe the top 1% extreme situations, you have likely been psyoped.show more
