An aerator and an associated method and system are provided. The aerator includes an elongate body having a central bore that extends between proximal and distal ends of the body, and a plurality of channels formed in an outer surface of the body, the plurality of channels extending between the proximal and distal ends, and including at least two bends along their lengths. The bends in the channels help to provide a smoother flow of liquids passing through the aerator.

In one configuration, a hydroponic system for enriching a liquid with gas-bubbles is disclosed. The system may include at least one reservoir configured to temporarily store the gas-bubble enriched liquid. Each of the at least one reservoir may include an associated inlet port and an associated outlet port fluidically coupled with each other via a liquid-flow line. The system includes one or more pumps configured to cause movement of the liquid along the liquid-flow line, a gas supply feeding a gas (in one configuration, oxygen from a gas concentrator), and a gas-bubble generator provided on the liquid-flow line. The gas-bubble generator may be fluidically coupled to the gas supply to receive gas from the gas supply. The gas-bubble generator may be configured to generate a plurality of individual gas-bubbles of the gas received from the gas supply and mix with the liquid stream flowing via the gas-bubble generator.

What is proposed is an emulsifying system for an internal combustion engine, wherein the emulsifying system comprises an emulsifying device for producing a water-fuel emulsion and an injector for injecting the water-fuel emulsion in a combustion chamber, the emulsifying device being arranged within the injector. Also proposed is an emulsifying method for preparing a water-fuel emulsion for an internal combustion engine, wherein fuel is pressurized in a fuel pressure accumulator and water is pressurized in a water pressure accumulator and fed separately to an injector for injecting the fuel and water into an associated combustion chamber, and/or fuel and water are emulsified by means of an emulsifying device that is integrated into an injector.

A fine bubble generator for generating fine bubbles in a liquid without externally introducing gas. According to an embodiment, a liquid flows in a gap between a first helical part on an inner surface of an outer member having a tubular shape and a second helical part on an outer surface of an inner member in the outer member, so that cavitation occurs because of the decrease in pressure when the liquid flows out of the gap between the first helical part and the second helical part, and fine bubbles are generated in the liquid. In this process, the liquid flowing near the inner surface of the outer member swirls along the first helical part, and the liquid flowing near the outer surface of the inner member swirls along the second helical part, and cavitation is promoted by the swirl flows, and the amount of fine bubbles generated is increased.
