  • When you google the word convection, you get images like this one, a two D diagram of what happens in a saucepan when you put it on the stove.
  • And it seems to fit with experience.
  • Like sometimes I left the lid on a pan of spaghetti and the spaghetti is gathered together into a kind of donut shape.
  • And I can imagine the strands spinning around to form that shape.
  • But is it actually what's going on?
  • Well, it turns out the truth is a lot more interesting.
  • And I found that out by building an actual two D version.
  • You know, I like building two D versions of hydrodynamic mechanisms.
  • If you're into that sort of thing, consider hitting subscribe and clicking the notification bell.
  • My first thought was that it should be made of a single piece of glass, but it needs to be resistant to thermal shock.
  • So.
  • borosilicate.
  • But that's hard to work with, and it would need to be fashioned from sheets of glass, not blown glass, which can end up cloudy.
  • You can see that here in the first iteration of my glass pop pot boat that had a flat boiler.
  • So in the end, we went with polycarbonate, which you don't want to get too hot, but it should be okay.
  • My first thought was that I should heat it from the middle only.
  • That way there'll be a very clear route for the liquid to take in its little cycle around the container.
  • So only this small section here is aluminium,
  • Like if the whole bottom part was aluminum and I heat it from the middle, eventually that heat would spread out because aluminum is a good conductor of heat.
  • I made the container quite tall because I wanted to see what kind of movement you got for different heights of liquid in the container.
  • There's also the question of how do you visualize how the water is moving?
  • And I had a few ideas for that.
  • The first was to make the liquid rheoscopic, and that's what you're seeing here.
  • That's really easy.
  • You just add mica powder to water.
  • The tiny flakes of mica tend to line up with each other locally.
  • And as the water around them twists and changes direction, these lined up flakes reflect light in different ways according to the orientation of the flakes.
  • And so that's how the flow becomes visible.
  • I haven't yet found an explanation for why the mica flakes align with each other locally.
  • which is annoying.
  • And here it is.
  • It takes a little time to get going, but I love the way it looks like the smoke from a candle flame.
  • If I speed it up, the resemblance is even more striking.
  • There's some interesting detail here that isn't really conveyed in the traditional diagrams that you get shown at school.
  • You get fast turbulent flow in a narrow channel in the center,
  • and a slow descent in wide channels either side.
  • That might be down to the fact that I'm heating it from the middle only.
  • So here's a new container where the hole of the bottom is an aluminium strip.
  • The flow still seems really chaotic
  • Sometimes it seems as though you can see different convection cycles, but then they break up.
  • At one point, the whole container is just one giant cycle, but again, it doesn't last very long.
  • Rheoscopic liquid gives you a sense of which parts of the liquid are in motion, but it doesn't necessarily give you a great sense of like the velocity of the liquid.
  • It does to a degree, but I wanted to see if I could do better.
  • My first thought was to use some kind of neutrally buoyant particle.
  • In other words, find some material that has the same density as water, which is one gram per cubic centimeter.
  • That was the original definition of a gram, by the way, one cubic centimeter of water.
  • So a lot of plastics have a density close to one gram per cubic centimeter, but no plastic nails it.
  • And then I thought, well, hold on, I only need to find a plastic that has a density somewhere between the density of water and the density of salt saturated water, which is about one point two grams per cubic centimeter.
  • ABS fits the bill nicely and just by trial and error I found the right amount of salt to get those ABS particles pretty much neutrally buoyant.
  • The problem is they stuck together and that's annoying and they seem to stick to the sides a bit so it doesn't really help to visualize the convection currents.
  • You can buy special particles that are a precise mixture of different plastics that give you one point zero zero grams per cubic centimeter of density.
  • The problem with those is
  • they're really expensive.
  • So I tried something else, water beads.
  • Water beads are made of sodium polyacrylate, which has a density of about one point two, which isn't great, except because they absorb hundreds of times their own weight in water.
  • Once they're saturated in this way, their density is extremely close to one.
  • And importantly, they don't stick to each other or the sides of the container.
  • The question then is, would the convection current created in this to deconvection current viewer be strong enough to lift the beads off the bottom?
  • And it turns out they are.
  • That's quite nice, isn't it?
  • But I really wanted to see a good flow of particles.
  • So you know what?
  • I bought the expensive beads.
  • I bought them.
  • It's about a third the cost of gold by the gram, which might be the most expensive substance I've ever bought.
  • Actually, maybe not.
  • Actually, what's nice about these beads is they're fluorescent, so they really stand out if I shine this UV lamp on them.
  • And I'm sure this is something you already know, but this convection flow we're seeing here is driven by changes in buoyancy.
  • When the water at the bottom is heated, it becomes less dense, it becomes more buoyant, and so it rises to the top.
  • At the top, when it's further away from the heat source and closer to the cool air, it cools back down again.
  • It condenses, becomes less buoyant, and sinks back down.
  • When it reaches the bottom, it heats up again, and the cycle continues.
  • And because when it reaches the top, it doesn't have anywhere to go except left and right, you end up with these two cycles.
  • Another way to view the convection current, actually, without using a marker at all, is by looking at something akin to heat haze.
  • As the water heats up, it becomes less dense, bends the light differently,
  • and that distorts this checkerboard that I put behind it.
  • There's a convection phenomenon that I really wanted to try and reproduce.
  • It happens on the surface of the sun, for example.
  • You get these convection cells.
  • So if you have a thin layer of convecting fluid, it breaks up into these smaller units.
  • I should be able to get that by just making the water in my convection viewer shallow and heating the whole of the bottom.
  • I think it's possible to discern a few different convection cells here, but they're not fully independent of the whole body of liquid.
  • Like there seems to be a general movement outwards across the top and inwards across the bottom.
  • And when I do it again with rheoscopic fluid, it seems really chaotic actually.
  • Even just in a Petri dish it doesn't seem to work either but I was aware of this working with oil instead of water.
  • So look here's that mica in just cooking oil now and look at those lovely convection cells.
  • I'm just heating the base of the Petri dish with hot water from the kettle
  • That's amazing, isn't it?
  • Quite fast spinning convection currents there.
  • And then you've got this slow movement as the cells change shape and merge and move around.
  • This is called Rayleigh Barnard convection, by the way, when you have these stable cells.
  • Apparently, if you get the conditions just right, those convection cells will spontaneously form into a regular hexagonal lattice.
  • I thought the trick would be to make the layer of oil really thin, but I can never get hexagons myself.
  • So with oil, it seems that you can get those multiple convection cells set up when you have just a shallow layer of convecting fluid.
  • So let's try the oil in the two D container.
  • And there you go, it's cool, isn't it?
  • Look at those individual convecting cells.
  • And there's hardly any turbulent flow at all.
  • And for completeness, here is a full container of oil heated evenly from the bottom.
  • And you can see that the flow is a lot less turbulent.
  • That's because oil has a higher viscosity, which means for the same flow rate, less turbulence.
  • And it seems like the convection cells are a bit more stable with oil, though it is still quite chaotic.
  • It's not just on the sun that you get these convection cells, of course.
  • They're an important part of the weather system here on Earth.
  • You get Hadley cells that take warm air from the equator and deposit it further north and additional convection cells at higher latitudes.
  • We typically think of convection being driven by differences in temperature, but it's not the only way.
  • If you take a dark colored liqueur like Tia Maria and you pour cream very carefully on top, you also get convection.
  • But this is solutal convection.
  • It's driven by changes in concentration.
  • In this case, the Tia Maria that's close to the surface loses alcohol by evaporation, becomes more dense, and then falls down to the bottom to be replaced by Tia Maria from lower down that has more alcohol in it.
  • that alcohol evaporates and the cycle continues.
  • Again, this is driven by changes in buoyancy, but buoyancy is changing for a different reason.
  • It's not obvious why the cream is important, but it does seem to be.
  • Convection can also be driven by changes in surface tension, and the cream might be influencing the system in that way, but I don't believe anyone knows for sure.
  • I'll link to one useful paper that I found though.
  • Something really weird happens when I search through my comments for the word Henson.
  • Basically, lots and lots of people banging on about how good the Henson AR thirteen safety razor is.
  • I mean, it's not that weird when you consider the fact that all of those comments are on a video that was sponsored by Henson Shaving.
  • But it is really unusual to get just that much positive feedback about a sponsor.
  • And actually, it made me realize that I made a mistake in the last sponsorship read.
  • Like, I thought I was being really clever talking about the dubious business model of cartridge razor brands.
  • It's literally called the razor and blades model and it's a massive false economy.
  • But that's not what the commenters care about.
  • They just seem to really enjoy the experience of using the Henson AR thirteen.
  • So let's look at why that might be.
  • Well, it comes down to two things, basically.
  • Precision and blade support.
  • The solid aluminium body gives incredible support to the blade, which you just don't get on cartridge razors, almost by design, actually.
  • But with all the support in the world, if the blade is in the wrong position, you're not going to have a good shave.
  • Well, Henson is a family run aerospace machine shop that pivoted to making their own products, so these razors are made using CNC machines to aerospace standards.
  • Like, once the blade is installed, it protrudes just thirty three microns from the shave plane.
  • There's not much room for error there.
  • I mean, this is all good information to know, but when it comes down to it, like, I just wouldn't shave with anything else now that I've tried the Henson AR thirteen.
  • And neither would any of these people in the comments section.
  • And just for comparison, I shaved this side of my face with the leading cartridge brand and you can really see the difference.
  • And I will just make this point again, like you could buy a cheap razor handle and get stiffed on the cartridges for the rest of your life, or you could pay a reasonable price for this precision engineered all metal handle that's going to last a lifetime and then get the blades for literal pennies.
  • If you're interested, the promo on this one is really good.
  • If you go to hensonshaving.com forward slash stevemould and use promo code stevemould at checkout, you'll get a hundred free blades with your Henson AL XIII safety razor.
  • Just make sure both of those items are in the basket when you apply the code.
  • That's equivalent to three or four years of shaving.
  • The link is also in the description.
  • So check out Henson Shaving today.
