Ranque-Hilsch (vortex) tube with water as fluid

AI Thread Summary
Using water instead of air in a Ranque-Hilsch vortex tube presents challenges due to water's higher density and viscosity, which may affect the device's performance. The compressibility of air allows it to cool upon expansion, a property not shared by water. The lack of existing research on water as a working fluid in this context raises questions about its feasibility. Understanding the underlying physical principles could help predict the effectiveness of water in this application. Overall, the discussion highlights the need for further exploration into the use of water in vortex tubes.

I'm very interested in building this cool device, and was wondering if water could be used instead of air as the injected fluid.

The main differences I notice are the much larger density, and thus possibly smaller angular velocity. And higher viscosity, which could mean a smaller radial gradient of temperature.

I've also had no luck finding people using water instead of air, but alas no explanation why not either.

If the physical principle why it works was known, one could predict if water would work or not.

What do you think or know?

Air is compressible and water isn't, which is why air cools when expanded.
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
