A flow cell for use in a fluid management and/or processing system is disclosed, said flow cell comprising a body having an inlet and an outlet and a fluid flow channel extending from the inlet to the outlet. Said body further comprises a receptacle comprising a chamber forming a part of the fluid flow channel, said chamber comprising a first opening for connecting a functional element to the flow cell such that the functional element is in contact with or exposed to a fluid flow passing through the fluid flow channel. A first tubular connector is arranged adjacent to the inlet. A second tubular connector is arranged adjacent to the outlet. The flow cell further comprises a functional element and a fluid flow path extending from the first tubular connector through the inlet, the body, the receptacle, and the outlet, to the second tubular connector.

A mixing tube for an exhaust treatment assembly, the mixing tube extending along a tube axis and having a first end and a second end; the mixing tube comprising a first longitudinal tube portion at the first end and a second longitudinal tube portion in between the first longitudinal tube portion and the second end; wherein the first longitudinal portion comprises a first set of regularly spaced openings for allowing an exhaust flow to enter the mixing tube and wherein the first longitudinal tube portion and the second longitudinal tube portion are separated from one another by a flow guide component arranged within the mixing tube such as to separate an injection area from a mixing area in the mixing tube; and exhaust treatment assembly comprising the mixing tube.

A flammable gas diluter includes a dilution vessel having an outer envelope defining a longitudinal flow passage from an inlet to an outlet; at least one air inlet assembly for directing a flow of air into the inlet of the dilution vessel; a flammable gas inlet arrangement located towards an inlet end of the dilution vessel; two gas flow generators configured to pump a flow of air into the air inlet assembly, the two gas flow generators being located upstream of the flammable gas inlet arrangement; and two dampers, each of the dampers being mounted between a corresponding gas flow generator and the dilution vessel. Control circuitry is configured to open a damper during an operational mode of the corresponding gas flow generator and to close the damper when the corresponding gas flow generator is stopped in standby mode.

Method and Apparatus for passive mixing of a multiphase flow or hydrodynamic performance that is housing a conduit/tube, which is a channel extending internally from the fluid inlet to the outlet ports, comprising axially stacked plurality of static mixers possessing structural elements or mixing elements (possessing structural elements on their inner walls), that are responsible for continuous splitting, and combining of the flow through the conduit, bringing about enhanced mixing of the contents of the flow, mass-transfer, and heat transfer. The structural elements bring about an enhanced mixing of multi-phasic systems passing through the conduit such as liquid-liquid, liquid-gas-liquid, and systems comprising immiscible and viscous liquids. The mixing elements or structural elements are responsible for splitting of flow into sections of multiple streams, followed by forced recombination of the multiple streams which is responsible for the equitable dispersion of individual components of multiphasic flow, thereby enhancing mixing of flow.
