what causes the vacuum in the boiler is actually really neat. basically as the water cools it condenses which creates a negative pressure (vacuum) inside the boiler which also in this game is simulated that it sucks the water into the boiler faster. pretty fascinating stuff and its also really neat

@@stormworksgamer922 Good, then we have another game to have him pick apart from Hyce's point of view. I feel like this will be at least interesting to him. Especially that the sounds are made because of things happening in the model and not as pre recorded sound files.

Ange is really good programmer, he made engine simulator (not steam one) and is able to reproduce many engine configurations and making software for generating engine sounds for games. BeamNG developers are even supporting him. :)

There's another mode. If you click on the A icon in the lower-right corner a few times, it unlocks "hell mode". It's possible to get the engine up to several thousand RPM.

Look next to the water valve, it says water at 50psi. It's a low pressure source, not a high pressure injector. You had more than 50psi of boiler pressure which is why you couldn't add water. In theory, unless there's a one way valve that's not displayed, you should have had water leave until boiler pressure equalised at 50psi. The amount of water is a balancing act. Think of of ANY fluid tank. Open a valve and the fluid will flow out at a set rate and do so for a specific period of time. Make that tank half the size with the same valve at the same rate, and the period of time it flows is halved. Your boiler is that tank, steam is your fluid and half water filled to 50% is cutting your "steam tank" capacity in half. Of course, you can't make steam without hot water so you need some and every time you add water it reduces the temperature which reduces or stops steam production. So the percentage of fresh cold water to existing hit water affects much much steam production is affected. So, you need sufficient hot water to maintain good steam production, whilst keeping enough room for a good supply of ready to use steam.

you've got a big issue with your reasoning: the quantity of steam isn't the determining factor for pressure the heat stored in the water is. this happens at about 1500 times the rate at which the heat can transfer through the mass of the water and happens from the entire volume of water (all the water is steaming not just the surface) the pressure will fairly steadily rapidly equalize to match the the stored heat regardless of the water level provided that there is at least a tiny bit of space to work with and at least enough water to act as a buffer/bleed for the energy interactions so the actual minutiae of those interactions keep looking close enough to belonging on a napkin instead of constituting a doctorate dissertation for every instant. the trick here is that you can't get the boiler pressure down without cooling it down or running it dry or VERY rapidly dumping pressure from the tank (bad idea: can go boom) and you can't add water without that pressure down so with the way it is all set up you need to either just run the system at roughly intake pressure (oh hey! looks like it is calibrated to stabilize at a touch above 50, fancy that) or periodically cool it way down to add water if you can't generate an injection pressure of near the desired running pressure, note that you need WAY less power to pressurize the water feed than you are generating, that 1500 expansion factor of water -> steam is really handy like that...I guess technically you could add water from low pressure while running just using the bleed valve if you do it as it goes dry and the boiler starts to overheat? but that would flashboil in spurts which would make the whole thing into a bomb due to the uneven heatcycles in the material in a matter of just a few cycles let alone over the course of prolonged regular operation. note: temperature = pressure through humidity relationship stays even below boiling (you can _technically_ run a steam engine on it being only a tiny bit warmer than the ambient temprature but the harvestable margin of workload is basically nothing below boiling) that's just the point at which the interaction goes from stabilizing in a slow diffusion to nearly instantly. note2: just to be clear when I call this thing a bomb while talking about ways to force it to fail that is REALLY not an exaggeration, pressure vessel ruptures can be horrifying up close even clear down at "bicycle pump + plastic bottle" let alone something like a large heavy duty boiler storing up more and more energy until either it finds the meeting point between the pressure from air expansion slowly building up and the heat changing everything's sizes and weakening materials or some unfortunate misguided soul panics and adds water in the middle of that process and fastracks all that heat all turning almost directly into pressure...I think that's actually a large part of why the tank is built like that: lots of stuff that looks like intended failure points and "not-a-valve" seams, everything is in tiers of "this should all fail at about this point" with the actual tank being the last thing on that list but that's me looking at it and thinking right now not returning known information.

@@evernewb2073 at 1 bar, the "expansion factor" of steam is about 1700:1 steam to water. Close enough to 1500 for basic "how much steam does boiling make" purposes, but not close enough for a steam engine. I'm not sure where you got that the expansion factor and the rate at which heat can conduct/convect through liquid water vs the rate at which water can boil volumetrically are the same thing (i.e. also 1500). That's a bit weird and very incorrect as this is entirely dependent on the temperature of the water and the geometry of the boiler. Related to my first point, the "expansion factor" of water into steam is actually only 1:400 (ish) at 50psig (aka 64psia or psi absolute). The expansion factor changes in relation to pressure. This "simulator" doesn't actually (correctly at least) simulate any of that though. For some reason Kosmo gets the boiler gauge pressure down to -25psig? Like wut? That's 10 psi below atmospheric pressure and its physically impossible unless you're running this steam engine 23 feet under water. Its like having a temperature of -100 Kelvin.

@@joebideng9226 You understood none of what I said. I'm not saying it again. It was perfectly clear. Have someone else explain it to you.

The thing that verified to me most (without looking into the game properly) that the simulation is probably accurate is the fact that as the pressure drops the water starts evaporating significantly faster. Basically, as the pressure drops the boiling point of the water drops too. So the water must start boiling off rapidly, carrying off heat so that the liquid water drops temperature quickly enough to remain at boiling point rather than sitting above it.

Advice: Have patience and wait for the water get to 300 C and Max Pressure,and then start it with the engine starter,and apply extremely little pressure into the chamber,and slowly open the valve at max!

Oh nice to see you play this, I was wqnting yo know it but were lazy to try. Btw, the smaller thing on the valve indicates that it doesn't block steam so yeah there's a way out. That piston keeps switching between both entrances as you would initially expect.

there's a funny thought: based purely on the sound of that whistle and it's size in relation to everything else this steam engine is MASSIVE. ...actually, that's really the only gripe here: the sounds are generated well but the baselines are all over the place: the scale on each sound source is completely separate. that said getting it even vaguely right is actually pretty damned impressive considering this is literally one guy making the thing as a pet project because the mostly nonfunctional "game" they made as a way to make an animation for a youtube video was a meme in their little community.

Typing out the word sorry makes it return to it's normal mode as well.

in reality you dont have anywhere nearly as much control over the furnace as you think you do, the best way to control the temperature in that case is to cool the boiler with fresh water and leaving the furnace doors open. water cant flow into the boiler if its overpressurized or equalized so the whistle also acts as a quick way to release some pressure, since using the pressure purge valve will dump it all out, the water purge valve is mainly to control how much steam you can actually store since too much water means less space for steam. also you dont actually need that much pressure to get a train going unless it has a very heavy load, a train will move with even as little as 30 psi, but a consistent 50 psi is often better for long term sustainability, though at 50 psi the chamber equalizes so you cant feed any more water into the boiler until the pressure drops.

Some "sophomore" level things to keep in mind when it comes to steam engines is that the generation of steam means the expansion of water vapor. Meaning you need space for that expansion to happen or at least be able to flow from. Water does not compress, so the more water you have in the boiler tank, the less room steam has to expand. It's not quite the basics and it's not advanced tips, it's midway between. People seem to forget that steam is expanding and liquid water will not compress.

"we're venting pressure now, i wonder what that means..." hmmmmm, i wonder what it could mean... maybe your pressure is too high, just a thought.

the start is reallly painful because i already know how this works

Activate Devil mode by clicking on the A a bunch of times. it lets you go faster.

*chillicothe 1948 PTSD intensifies*

I doubt Kosmo will see this but if any one finds this video and this comment later: click on the A a bunch of times (this gets you to a modded version that is overall better) set fire to 100 close safety valve set throttle to 58% open water valve fully this should cause the water to flash steam and you should have a perpetually running engine. If your tank fills with water drain and start again. Psi should not exceed 48/49 so the water will flow into the boiler and flash steam. I spent the time to get all the achievements for this game and in the end it was worth it. The creator of this game is doing some really amazing things and is worth checking out.

Oh Boy! In a real boiler putting a hot dry boiler (ike a boiler boiled all the water out of it) and then put it into cold water will cause it to instantly flash it to a boiling explosion. It is a very dangerous thing to do. Will your simulation do that?
