Apparatus for controlling flow of fluid in a fluid body containing a first fluid, the apparatus including: a baffle at least partially submerged in the fluid body, the baffle including: in inlet that in use is coupled to a fluid supply adapted to supply a second fluid; at least one outlet; at least one internal channel extending from the inlet to the at least one outlet to thereby allow second fluid to be expelled from the at least one outlet; and, an outer surface which acts with the at least one outlet to at least partially guide second fluid expelled from the outlet to induce flow within the fluid body and thereby agitate the fluid body.

An aeration apparatus includes at least one aerator, a frame fluidly connected to the at least one aerator, and an aeration source fluidly connected to the frame. The aeration source may be configured to deliver air to the at least one aerator via the frame to oxidize fluid held in the at least one aeration chamber.

A method for designing a baffle including using patterns to produce an array of shell moulds, generating a 3-D image of the outer surface of each shell mould in the array of shell moulds, stacking the individual 3-D images for a plurality of the shell moulds to produce a conglomerate shell mould profile, determining a maximum cross sectional area of the conglomerate shell mould profile in a plane orthogonal to a direction along which the shell moulds are to be drawn through the baffle, defining a baffle profile segment which is consistent with a substantial portion of the conglomerate shell mould profile at the maximum cross sectional area, scaling the baffle profile segment to provide an offset clearance between the baffle profile segment and the maximum cross sectional area of the conglomerate shell mould profile, and reproducing the baffle profile segment to provide an array of baffle profile segments.

The present disclosure relates to a nanobubble generation system using friction in which a frictional force is applied to bubbles included in a gas-liquid mixed fluid so that the atomization of the bubbles is induced and nanobubbles are generated. The nanobubble generation system includes: a chamber including an inlet, an outlet, and an internal space S configured to atomize bubbles included in a gas-liquid mixed fluid; one or more strikers each including a plurality of protrusions provided on a body thereof to simultaneously apply impact to the gas-liquid mixed fluid that flows into the chamber and swirl the fluid in order to cause the gas-liquid mixed fluid to rub against an inner wall of the chamber, the strikers being provided on the driving shaft; a plurality of friction elements provided on the driving shaft in order to apply frictional force to the gas-liquid mixed fluid; and a driving mechanism including the driving shaft and configured to rotate the striker and the friction elements, wherein the friction elements are arranged on the driving shaft to be spaced apart from each other at a predetermined interval, and peripheral surfaces of bodies of the friction elements directly face the inner wall of the chamber with a predetermined distance therebetween.

Provided is a washer liquid supply system in a simple structure and capable of improving the capacity of washing an object of a vehicle. A washer liquid supply system includes: a washer tank mounted on a vehicle to store washer liquid; a supply section mounted on the vehicle to supply the washer liquid in the washer tank to a window shield of the vehicle; and a connecting member being a bubbling section mounted on the vehicle to make the washer liquid contain bubbles, wherein the supply section supplies the washer liquid containing the bubbles to the window shield.

The invention comprises an improved venturi apparatus and method of use.

Apparatuses and methods for liquid control are provided. A liquid control apparatus may be for selectively treating and/or substituting a liquid flow from at least one of a plurality of supply lines. The ultimate liquid flow is for dispensing to a user by way of a liquid supply fixture such as a tap. The apparatus comprises a liquid conditioning module for connection in-line with at least one of the plurality of supply lines. The liquid conditioning module receives a diverted liquid flow of the at least one supply line from an upstream portion of the supply line. It then outputs a selectively treated and/or substituted liquid flow for returning to a downstream portion of the supply line for dispensing to the user. The apparatus has at least one flow sensor, each flow sensor associated with one of the plurality of supply lines. It has a controller, the controller configured to receive information indicative of the liquid flow of at least one of the plurality of supply lines from the at least one flow sensor. The controller, upon the occurrence of a predetermined flow characteristic, is operable to activate the liquid conditioning module to treat and/or substitute the liquid flow from one or more of the liquid conditioning module connected supply lines in order to provide a treated and/or substituted liquid flow at the liquid supply fixture.

A multi-stage oxygenator includes a submerged fluid-tight pressure vessel that has first, second, and third sections. A baffle divides the second section into compartments, and a water delivery mechanism delivers water into the second section via the first section. An interface between the first and second sections delivers water to the compartments as water jets or droplets, creating flooded zones. A gas delivery mechanism delivers oxygenated gas into a compartment to create a gas void, through which the water jets or droplets fall, between its flooded zone and the first section. A gas connection through the baffle allows gas from the compartment to create another gas void in a subsequent compartment in series therewith. A gas release device maintains the gas voids by releasing gas from a last compartment. The third section connects the compartments allowing water from their flooded zones to mix to produce treated water that is outputted.
