A turbine system includes a foam generating assembly having an in situ foam generating device at least partially positioned within the fluid passageway of the turbine engine, such that the in situ foam generating device is configured to generate foam within the fluid passageway of the turbine engine.

A delivery system for mixing and dispensing a gel stemming material into a blast hole is disclosed. The system includes a dual-pump assembly in fluid communication with respective sources of a first gel precursor fluid and a second gel precursor fluid; a pair of hoses associated with a means to vary an effective length of said hoses; a dosing head having a first inlet and a second inlet, said inlets arranged in respective fluid communication via said hoses with the dual pump assembly to receive the first and second gel precursor fluids, the dosing head being configured to receive and mix the first and second gel precursor fluids to produce the gel stemming material and to dispense the gel stemming material via an outlet. In use, the effective length of the hoses may be varied to position the dosing head and dispense the gel stemming material in the blast hole.

A distribution tube for a static mixer provides efficient mixing with improved performance over a wide range of flow rates. The distribution tube is positioned near an inlet side of the static mixer. An injected fluid is introduced into the static mixer via the distribution tube, which pre-mixes the injected fluid with a main fluid prior to further mixing by mixing elements of the static mixer.

A mixing chamber is loaded with a first fluid. While a volume of the first fluid within the mixing chamber is constant, first and second streams of a second fluid are injected into the mixing chamber along first and second injection directions. As a result of injecting the first and second streams of the second fluid into the mixing chamber, the first and second streams of the second fluid impinge one another so as to generate within the mixing chamber at least one further stream of the second fluid that mixes with the first fluid and that flows in a direction different to the first and second injection directions.

A capsule includes an upper body portion and a lower body portion that is coupled to the upper body portion. The lower body portion includes a lower wall that defines a lower opening. The lower body portion and the upper body portion together define an internal cavity. At least one of the upper body portion or the lower body portion includes a plurality of grooves spaced at intervals along a circumferential direction with respect to a central axis of the capsule. The plurality of grooves extends at an angle in a partially axial direction and a partially circumferential direction.

A nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer air flow path, and a core conduit defined radially inward from the inner gas flow path. An injector assembly includes an outer housing, a nozzle within the outer housing, and an outer housing gas flow path defined radially outward from the nozzle between an inner surface of the outer housing and an outer surface of the nozzle. The nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer gas flow path and a core conduit defined radially inward from the inner gas flow path.

An apparatus for mixing wash water and crude oil includes a crude oil pipe, a wash water manifold, a plurality of conduits, and a flow controller. The crude oil pipe includes a wall having an interior surface, an exterior surface, and a plurality of wash water injectors. The plurality of wash water injectors are angularly distributed on a circumferential band of the wall of the crude oil pipe. The flow controller is operable to regulate wash water flow through the plurality of conduits. Each of the plurality of wash water injectors is fluidly coupled to the wash water manifold by one of the plurality of conduits. The plurality of wash water injectors are arranged to provide mixing of the wash water and the crude oil when the wash water is injected into the crude oil pipe through the plurality of wash water injectors.

One aspect relates to a device for mixing two liquids including a tube having an open end, a main line connected to the tube in a liquid-permeable manner, a rubber-elastic body delimiting a line wall of the main line, at least one secondary line in the rubber-elastic body, wherein the at least one secondary line extends from at least one secondary opening up to the main line and opens via at least one mouth into the main line, a main connection for introducing a first liquid into the main line, at least one feed line for introducing a second liquid into the at least one secondary line, which is connected to the at least one secondary opening in a liquid-permeable manner. The at least one secondary line is closed in the rubber-elastic body without the action of a force and is hydraulically openable by a pressure being exerted on a second liquid fed to the at least one secondary line by an elastic deformation of the at least one rubber-elastic body. The open at least one secondary line closes without a pressure being exerted on the supplied second liquid by the restoring force of the elastically deformed rubber-elastic body.

A liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are contained in the chamber. The first conduit connects the chamber to an outlet port in the container were the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an exiting flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.
