Acoustic Power
Contents
(Click an item to go

 The
Piston Made of Air (4th edition),
The Kadenacy Effect
and its use in the driving of pulsejets and pulsating combustors, and in
the tuning of two-stroke exhaust systems. Could help perfect the
Neal equalizer. Includes plans for a rudimentary pulsejet model.
Item #08-05
Acoustic Power Devices, 2nd edition,
Bellocq/Bentley/Bodine
and how they do all kinds of pumping and other work with nothing but sound
waves; fluid friction heaters, pulsometer pump, ram pump,
reciprocating-jet pump, hydropulse engine, acoustic levitation.
Item #10-05
Constantinesco Treatise,
Theory of Wave
Transmission, an engineering textbook by
George (Gogu) Constantinesco, which pertains to machines that do
various kinds of work due to energy delivered by a flow of a vibrating
fluid. This is one of the best sources of information on this type
of machine. Constantinesco was the "Thomas Edison" of his country.
Item #12-05
Thermoacoustic Heat Pumps,
Tim Lucas of
Macrosonix and his high-pressure sound-powered refrigeration, articles and
patents detailing the origin and history of the new field of acoustic
refrigeration.
Item #46-00
Energy Exchanges in Vibrating Fluids (2nd edition),
Resonators, vortex
rings, resonating jets, resonance in piping, waterhammer, wave dynamics,
noise reduction.
Item #11-00
THE PULSOMETER PUMP
Rotary Pressure Exchangers,
Pressure wave machine,
equalizers and dividers, wave rotor, wave engine, all names for this type
of air compression technology which uses waves to induce two gases at
different pressures or temperatures to mix, producing a mixed gas at an
intermediate pressure/temperature. The pressure exchanger, unlike
the vortex tube, is a non-dissipative device. On a related note, the
pressure exchanger—like a heat pump—can move more energy than it takes to
operate. They are being used as superchargers for big diesel
engines. The pulsed-jet pump does basically the same thing, without
moving parts.
