摘要： The present invention provides a system for enriching a flowing liquid with a dissolved gas inside a conduit. The system comprises two or more capillaries, each capillary delivering a stream of a gas-enriched liquid to the flowing liquid. The first ends of the capillaries are positioned to form an intersecting angle with respect to the effluent streams such that these streams of gas-enriched liquid collide with each other upon exit from the first ends of the capillaries, effecting localized convective mixing within the larger liquid conduit before these gas-enriched streams are able to come into close contact with the boundary surfaces of the conduit, whereby the gas-enriched liquid mixes with the flowing liquid to form a gas-enriched flowing liquid. In the preferred embodiment, no observable bubbles are formed in the gas-enriched flowing liquid. Methods of making and using such system are also provided.
