Embodiment Construction

[0025] The present invention will be described herein for purposes of illustration and not limitation with reference to a water augmented inert gas fire suppression system for use in fighting fires in commercial buildings. It should be understood that the present invention is not limited in application to fire suppression systems, but may also find application in conjunction with other two-phase flow systems, including but not limited to steam-based oil recovery systems, natural gas pipelines, cooling systems for refrigeration systems and nuclear power plants A fluid network, or any two-phase flow system operating in an annular flow regime.

[0026] now refer to figure 1 , the fire suppression system 10 may include one or A plurality of containers 20, a liquid storage container 30 and at least one drain 40 are associated with the area to be protected. However, except when the area to be protected is a single relatively small room, usually a plurality of discharge devices 40 ...

Abstract

A flow splitting device for use in a two-phase flow distribution network includes a side junction three-way pipe having a first conduit and a second conduit opening in flow communication to the first conduit, a flow restriction device provided in the first conduit upstream of the opening of the second conduit with the first conduit, and a flow barrier extending into the first conduit at a location in the vicinity of a downstream edge of the opening of the second conduit to the first conduit. The ratio of the liquid phase mass flow to the gas phase mass flow is preserved as the mass flow ratio of liquid to gas to each of the two exit streams is substantially equal to the mass flow ratio of liquid to gas in the two-phase flow received by the flow splitting device.

Description

technical field [0001] The present invention generally relates to two-phase flow distribution systems. More particularly, the present invention relates to improved liquid distribution within the gas streams of a pair of two-phase flow streams emerging from the two outlets of side joint tees incorporated in the distribution piping network. Background technique [0002] Pipeline distribution networks are used in a variety of applications to convey a pressurized two-phase flow of liquid carried in a gas stream from a source to multiple endpoints. For example, applications of such pipeline distribution networks include, but are not limited to, oil fields carrying steam through pipeline networks for oil recovery, natural gas distribution lines, cooling networks for nuclear power plants and refrigeration systems, and fire suppression systems. To facilitate the distribution of two-phase flow between multiple end points, such piping networks often incorporate one or more tees. [...
