Abstract
A system and method for delivering a gas-supersaturated fluid comprising a fluid reservoir, a fluid pump, a gas source, a high pressure gas exchanger, and one or more arrays of capillary channels is disclosed. Suitable controls such as differential pressure gauge and valves are provided to maintain a near constant hydrostatic pressure of the fluid within the semi-permeable membrane gas-fluid interface of the gas exchanger at approximately 1% to 20% higher than the gas partial pressure of the fluid within the gas exchanger. Gas-supersaturated fluid output from the gas exchanger via the capillary channels is at a flow velocity of greater than 0.05 m/sec, thereby facilitating delivery of large flow rates of gas-supersaturated fluids without cavitation inception.
