How does one amplify the velocity of a water convection cell on a very small scale (e.g. in a cooking pot or glass jar) to reach a velocity of ca.10 km/h?
It's going to be part of a greater experiment

Exactly my thoughts anon, but how to achieve that, is another question

Heat sinks.
I meant cooling it down at the top much faster than usual as to allow a higher velocity

Better heat conductor for the bottom of the container, poor heat conductor on the sides, blow cold air over the top.
Liquid nitrogen

more burners
But why?..
You could try running some glass tubing through a hot water bath, add some salt to the water in the loop, that will make sure the working fluid doesn't start boiling and explode all over you. The cooling portion could be a distillation column with ice water running through it, although all the swirly loops in the column will have a big impact on the flow though it. You also want to have the sections between the hot and cold sides insulated, and with a large elevation difference to increase the thermal driving head.
Maybe throw in some light flakes of plastic with neutral buoyancy so you can meter the flow rate with a yard stick.
Good luck with whatever the fuck you are planning.
