Is it possible to construct a solid state fluid system (tubing, channels, chambers, nozzles, etc.) that can convert the energy from a low-pressure high-flow-rate air current into a high-pressure low-flow-rate air current?
This is similar but not identical to this question, because in my case I am looking to use existing pressurized air as the energy source, but want to produce even higher pressure (even if the pressure is only slightly higher or there is significant energy loss). This question is also similar but seems to be asking a way to increase power, whereas in my case I don't care much about efficiency or power, only pressure. As an electrical engineer with no background in fluid dynamics, I see this problem as analogous to an electric transformer, with pressure being the analog of voltage and flow rate the analog of current. From an energy conservation perspective, it seems like it should be possible.
I realize the answer is trivial with pistons and gears but I am interested in a design that uses no moving parts, or if that's not physically possible, at a minimum uses only valves as moving parts. The hydraulic Trompe and Pulser pump are very close to what I want, but they involve water and gravity. I'm looking for something that uses only air.
The reason I am interested is because I've been reading up on pneumatic circuits and simple pneumatic devices, such as the Tesla valve, this pneumatic oscillator, and the complex no-moving-parts fluidic control circuitry described here. Particularly I am interested in constructing a "pneumatic integrated circuit", by stamping or carving channels and shapes into layers of some substrate and stacking them to produce tightly-integrated tubing circuitry in a single brick-like device. Valves that fully close may be possible in this scheme as described here. If such a pressure transformer is possible in an integrated context, I envision it could enable a variety of very simple and easy-to-build fluidic devices like audio amplifiers, mouth-operated musical instruments with artificial sounds, small-scale heat pumps and moisture collectors, and simple digital logic circuits, all powered only by moving air.
I would be grateful for any resources at all on fluidics that may be helpful, even if they don't solve my problem directly. Thank you for any answers!
