Disclosed are an apparatus and a method for forming a gas-liquid mixture having a stable vapor concentration. The apparatus comprises a mixing unit (1), a guide unit (2) and an evaporation chamber (3). In the mixing unit (1), a liquid stream is directly injected into a gas stream to form a mixture. The mixture is guided into the evaporation chamber (3) through the guide unit (2). The liquid is able to be spread over the rough inner surface of the evaporation chamber (3) so as to form a gas-liquid mixture having a stable vapor concentration. The technique can be applied to adsorption measurements using ellipsometry, as well as other research and products requiring use of stable and very-low-speed fluids.

An eductor for mixing a primary fluid with a flowable secondary substance includes a primary inlet for the primary fluid, a secondary inlet for the secondary substance, an outlet and a suction chamber, A converging inlet nozzle is provided, which is arranged between the primary inlet and the suction chamber so that the primary fluid can flow from the primary inlet into the suction chamber. An outlet nozzle is provided between the suction chamber and the outlet, through which the primary fluid and the secondary substance can flow to the outlet, and the secondary inlet is provided at the suction chamber so that the secondary substance can flow from the secondary inlet into the suction chamber.

A static devolatilization apparatus (1) for germ reduction of a fluid is disclosed. The apparatus (1) comprises a housing (10), an inlet (12), an outlet (14), a fluid-contacting surface (20) comprising a biocide (22) embodied to reduce the germ count of the fluid (2), wherein the fluid-contacting surface (20) is a fluid-contacting surface (20) of a static mixing element (30). The present invention further relates to a process for reducing the germ count of a fluid containing germs (2) using the apparatus (1) and also to the use of the apparatus (1) in the germ reduction of fuel oil, of food products, or water decontamination, preferably decontamination of waste water, industrial process water, or the treatment of drinking water.

A mixing funnel for mixing fluids is provided. In one embodiment, the mixing funnel includes a tray having a fluid inlet arranged to receive a primary fluid flow, and first and second fluid passages configured to receive primary fluid flow from the fluid inlet such that the flow is divided to flow along the first and second fluid passages. The first and second fluid passages can be arranged to direct the primary fluid flow to a mixing area. The tray can further include a fluid outlet arranged to receive the primary fluid flow from the mixing area and to deliver the fluid to a container.

A structured element intended to be in contact with at least one first fluid and one second fluid, the structured element comprising a surface for circulating fluids structured by the presence of air cavities with a depth of between 100 and 1000 m and distributed regularly over the structured surface, each cavity being delimited by a cavity surface. According to the invention, the cavity surface comprises at least one first zone and one second zone succeeding one another along a direction of depth of the cavity, the first zone being coated with a first set of particles having properties for repelling the first fluid, and the second zone being coated with a second set of particles, different from the first set.

The diffusing member of the present invention is disposed in an exhaust pipe to partially block exhaust gas flowing in from upstream of the exhaust pipe, the diffusing member including a ceramic member and a metal member, wherein the ceramic member surrounds the metal member in such a manner that the metal member is partially exposed, and the volume of the ceramic member constituting the diffusing member is larger than the volume of the metal member constituting the diffusing member.
