Device and method for fluid aeration via gas forced through a liquid within an orifice of a pressure chamber

A method of oxygenating water, comprising the steps of:

• forcing a continual jet of gas comprising oxygen out of a source opening;
• forcing water into a pressure chamber which pressure chamber surrounds the source opening and the jet of gas thereby forming a stable cusp at the interface between the gas and the water, forming a stable microjet of gas;
• allowing the microjet of gas to exit an exit orifice of the pressure chamber into a container of water whereby the microjet of gas disassociates and forms bubbles in the container of water;
• and
• allowing oxygen in the bubbles to diffuse into the water in the container;
• wherein the source opening and pressure chamber exit orifice are positioned such that the water surrounds the jet of gas and forms a stable cusp at the interface between the gas and the water, thereby forming a stable microjet of gas, and the gas microjet surrounded by the water is caused to move out of the exit orifice into water and further wherein the microjet undergoes acceleration based on an abrupt pressure drop on passing through the pressure chamber exit orifice.

A method of oxygenating liquid sewage, comprising the steps of:

• forcing a jet of gas comprising oxygen from a source opening;
• forcing a liquid into a pressure chamber which chamber surrounds the source opening, the pressure chamber having an exit orifice positioned downstream of the jet of gas exiting the source opening;
• wherein the liquid surrounds the jet of gas and forms a stable cusp at the interface between the gas and the liquid, thereby forming a stable microjet of gas, and the gas microjet surrounded by the liquid is caused to move out of the exit orifice into liquid sewage;
• wherein the stable microjet has a diameter defined by the following formula:
• d j ≅ ( 8 ⁢ ρ l π 2 ⁢ Δ ⁢ ⁢ P l ) 1 4 ⁢ Q g 1 2
• wherein dj is the diameter of the stable microjet of gas, ρ1 is the density of the liquid, ΔPl is the change in pressure of the gas at a point exiting the exit orifice of the pressure chamber and Qg is the flow rate of the gas.

A method of carbonating a liquid, comprising the steps of:

• forcing a jet of carbon dioxide gas from a source opening;
• forcing a liquid into a pressure chamber which chamber surrounds the source opening and the jet of carbon dioxide gas, the pressure chamber having an exit orifice positioned downstream of the jet of carbon dioxide gas exiting the source opening;
• wherein the liquid surrounds the jet of carbon dioxide gas while inside the pressure chamber and forms a stable cusp at the interface between the carbon dioxide gas and the liquid, thereby forming a stable microjet which exits the exit orifice of the pressure chamber;
• wherein the stable microjet has a diameter defined by the following formula:
• d j ≅ ( 8 ⁢ ρ l π 2 ⁢ Δ ⁢ ⁢ P l ) 1 4 ⁢ Q g 1 2
• wherein dj is the diameter of the stable microjet of gas, ρ1 is the density of the liquid, ΔPl is the change in pressure of the gas at a point exiting the exit orifice of the pressure chamber and Qg is the flow rate of the gas.
