LAMINAR FLOW IS BETTER. Obviously the Laminar Boundary Layer section was the best part of the video. (I jest.) In all seriousness though I thought you did an amazing job with this content Derek. Discussing the transition to turbulence is very difficult and you did a masterful job of it here. Animating Reynold’s experiment on the page was masterful. Your point that laminar flow must be small was very interesting, and when I saw the images from space I had a fun time thinking about what parts were laminar and what parts were turbulent. I’ll put a link to this video on the laminar flow video. All these nice things being said....I have something up my sleeve!

As an aerospace engineer I'm so glad this video was made. I love Destin's video on laminar flow but I kept thinking "but but but the flow is so much easier to separate if the flow is laminar" But also, you can't just mention that a dead fish can swim upstream in a sentence and move on! That deserves it's own video! How does something move upstream without it expending energy! How does an object move forwards when you blow on it! The only explanation I have is there is lower pressure closer to where the vortex is shed than far downstream, so the fish is being "blown" upstream by the pressure difference...

The oscillations must be high frequency enough to propel it forward. It is like the movement of a flag mixed with the behavior of a sail powering a boat against the wind. It uses the energy available in the water flow. This probably evolved so these fish can rest behind rocks when climbing rivers during the mate season. Once I saw a guy using genetic algoritms and fluid dynamics simulation to find optimal shapes of wind mills so it would be super efficient. Truely amazing.

Loved this! It’s quite apparent that turbulent flow makes life possible, but there is one very important use for laminar flow, and that is in biosafety. Biosafety cabinets are engineered to produce laminar flow in the air, and this creates a barrier that helps to prevent biohazards and pathogens from escaping the biosafety cabinet while working on biological experiments inside the cabinet. The laminar flow can push biohazardous material that has become aerosolized through the flow and into the HEPA filter before it leaves the cabinet space.

I'm a mechanical engineer and I once did a project in my senior fluids lab studying drag coefficients of rough spheres versus smooth spheres and other objects with round cross sections. We demonstrated that 1. The rough sphere had a smaller drag coefficient in the wind tunnel due to induced turbulence at the surface, and 2. You must always remember to prop open the door so that it doesn't slam closed when you power up the tunnel and disturb the computer science students in the lab next door.

Word When they were testing the cold weather capability of the SR-71 in a refrigerated hangar at eglund AFB in florida, the Lockheed guys asked the AFB guys if the hangars could handle the SR's engines airflow. They were told it was not a problem. So when the SR started up (with the exhaust piped outside to keep the hangar cold) It entirely collapsed the HVAC ducting in the hangar. OOPS.

Transport Phenomena is my favorite subject, I’m so loving this video

I love your videos and concepts, I love turbulence as the way they are and love those materials you use to show turbulence, like some kids balls these days in Kmart or toy shops but I love laminar flow too. It’s awesome as waterfalls that are chaotic transitioning to turbulence look awesome but small ones too. Their respective sound that they produce has same effect I.e disturbing or chaotic vs calm or pleasant. But I like both. Enjoy world

The paper is about a digital, self-powered sensor array to sense aircraft aerodynamic stall by triboelectric and piezoelectric nanogenerator, in title of “Digital mapping of surface turbulence status and aerodynamic stall on wings of a flying aircraft”. DOI: 10.1038/s41467-023-38486-6. We also believe triboelectric nanogenerator is an interesting topic that we can talk about.

I've been flying kites in this lockdown period everyday and one thing i noticed was when wind blows and lifts the kite and then at a certain point when its going steadily up, at a certain angle the lift developed in it suddenly becomes zero and its shoots down itself to the ground as if it was a crashing rocket and you can't stop it, now at 10:28 i realized why it happens, this question was really stuck in my mind for a long time

It very similar but kites work different than airfoils. Kites achieve lift from drag unlike airfoils. I imagine as the kite rises you actually get a lower angle of attack which in turn reduces drag and in turn, lift. Airfoils on planes stall with a higher angle of attack.

Nice name

I really enjoyed this video thank you

As a mechanical engineer who studied fluid dynamics, this was a great video with simple explanations to the complicated topic of turbulent flow. The immediate thing that came to mind when you said you wanted to make turbulent flow seem more awesome than laminar flow was using vortices to your advantage in vehicle aerodynamics. In Formula one cars they are not allowed to seal the floor containing low pressure for downforce with physical parts. They therefore generate vortices from wing tips that travel along the sides of the car to shield the low pressure region from the surrounding higher pressure air thus preventing a loss in downforce. This energised air is also easier to manipulate to flow in directions of choice. Another thing you notice in commercial plane wing tips is at the end there is a long curved piece that raises the tip vertical and away from the surface of the wing. This keeps the turbulent vortices coming off the wing tip away from the long wing surface which would disrupt the flow over the end of the wing and cause it to separate sooner. Also, another interesting characteristic of turbulent flow is how it is used in heat transfer to maximise temperature difference and thus improve heat transfer. I will let you research more about that one and maybe you could make another video about these awesome uses and convert Destin into thinking turbulent flow is so much better!

It's spelt "psych" as in "haha I psyched you out".

I studied Hemodynamics as part of a medical course in college, and one thing I noted that wasn't mentioned in this video was the creation of turbulence when moving from a smaller tube to a larger one in a pressurized system, such as the human body. This is something that can be seen on ultrasound when observing a stenosis of an artery, turbulent flow is important in diagnosing stenosis' in the Common Carotid Artery(CCA) and up into the Internal Carotid Artery(ICA) as this is the main source of blood flow to the brain. Laminar flow is the kind of blood flow you want heading to your brain, but there are people out there with coiling, kinking and even looping carotid arteries.

Relevant, clever and interesting. Laminar flow helps in surgery, using clean filtered air to push outward from the 'open' patient, who needs to be kept sterile. Thank you

This is the best part of this video. A fishes anatomy, it's bone structure, shape and fin flexibility whip past turbulent currents and make the fish swim upstream if there is turbulent flow. It uses the whirlpools coasting past its body to wrap itself around and flick past using its fins. This pushes the fish past the eddy current and makes it swim in the direction it was hit. The cool thing about this is that it doesn't matter if the fish wants to or not - it naturally swims from where turbulent flow comes from. If there is a whirlpool it will have flow going in a spiral, so it will have current travelling upstream anyway. This means the fish only coasts in that part of the whirlpools (because of its body shape) and glides in the upstream-flowing part of a whirlpool.

It creates the patterns of art - because that is the result that creates rivers and waterfalls, waves etc. It's chaotic beauty, but with some kind of predictability.

Turbulent transition in flow is caused by disturbances in the flow, which cause U shaped vortices to form called 'hairpin vortices' these eventually elongate in the streamwise directions (that are moving with time), the hairpin vortex is eventually lifted up to higher regions of velocity, which then eventually 'bursts' the vortex, causing high rotational energy to be dissipated everywhere, which shows the first turbulent spot. Some of this rotational energy is swept back to the surface repeating the process until a full vortex breakdown is achieved and the flow becomes fully turbulent.
