Re: Thermoacoustic engines
I'm a bit puzzled regarding how an oscillating gas (moving forward and back) can turn a turbine.
I thought it must be doing something like this:
The air shoots out in a jet, but gets pulled back in by the side.
This would only be powering the turbine during 1/2 of the oscillation.
So, I was thinking about doing something like this:

Re: Thermoacoustic engines
Yes, it works like a pulse jet, so theoretically it can only use up to half the energy, but it could certainly be improved, and thermoacoustic turbines work well only under pressure. There are also bidirectional turbines, but they are more complicated and choke the engine. It's possible that a unidirectional turbine, because it chokes less, can be more than 50% because if there is no resistance in the inward phase, it can gain momentum there in the phase that adds to the outward phase. For bidirectional turbines, the wells turbine is much faster but has less pressure, but is simple, other turbines may be better but more complicated. Under pressure, a good turbine can operate at efficiencies of over 90%. It's cheap, simple, lightweight, durable compared to a piston, and can be used in huge sizes. Turbines could be the future...

^^^ Nice one 50 led's is a lot but the flame does seem considerable bigger as a burning candle.
I noticed in comments people still rave on about the Tesla turbine. The reason why there no real use for it to this day is because it is about as unnatural as it gets. Turbos and such resemble more a "Schauberger funnel" or the Golden Ratio and Fibonacci Numbers and not Tesla turbine junk.

Re: Thermoacoustic engines
Funny you should say that. I always thought the Tesla turbine was the MOST natural as far as the actual air flow which forms into such a spiral with minimal artificial constraints.airpower wrote: ↑Fri Nov 26, 2021 2:22 am...

Very inexpensive, easy to build for DIY projects, perfectly "reversible" (works backwards as a pump). Hard to beat IMO, working almost identical to the Schauberger vortex.
The fluid spiraling down to the outlet in the center.

Neither the model nor the 50 LEDs here are meant to illuminate with it, but to provide some sort of comparison with previous results, or even other models...Nice one 50 led's is a lot but the flame does seem considerable bigger as a burning candle.
