A vehicle exhaust system includes an inlet module configured to receive engine exhaust gas and a mixer housing defining an internal cavity that receives engine exhaust gas from the inlet module. An injection component is positioned within the internal cavity and has a fluid inlet and a fluid outlet to direct injected fluid into the internal cavity to mix with the engine exhaust gas. The injection component defines an injection axis and includes an inner structure defining an inner gas flow path and an outer structure defining an outer gas flow path that is between the inner and outer structures and radially outward of the inner gas flow path to improve mixing at the fluid outlet. An outlet module is configured to direct a mixture of engine exhaust gas and fluid to a downstream exhaust component.

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.

Systems and methods related to preparing foamed cement for laboratory analysis are provided. A prepared cement slurry is placed in a cement reservoir cell configured to pressurize the cement slurry contained within the cement reservoir cell to a capture pressure.
