Disclosed herein is an apparatus for facilitating improving flow of fluid in a duct, in accordance with some embodiments. The apparatus comprises a first portion, a third portion, and a second portion. Further, continuously attaching an inlet edge using an attachment member and an outlet edge defines an interior space. Further, a first amount of the fluid entering a first interior space through an inlet opening flows to a third interior space with a first velocity and a first direction. Further, portions of a second amount of the fluid flows into the third interior space through second openings with a second velocity and second directions. Further, the fluid flows from the third interior space with a third velocity and a cyclonic flow pattern for exiting through an outlet opening based on interacting of the portions of the second amount of the fluid with the first amount of the fluid.

A rectifier and a flowmeter, the rectifier including a fairing, wherein a first rectifying section (1) positioned at the upstream, a reducing section (2) positioned at the midstream and a second rectifying section (3) positioned at the downstream, can be arranged in the fairing. The first rectifying section and the second rectifying section are respectively provided with a group of rectifying channels parallel to the flow direction of fluid, and a through-hole (21) can be formed in the reducing section. The rectifier can provide improved rectification effects.

In one example, a fluid flow restrictor has a housing outlet offset from a housing inlet along a fluid flow direction so as to define a channel therebetween. A rotatable body that is disposed in the channel defines a bore that extends entirely therethrough such that the bore defines a bore inlet and a bore outlet. The flow restrictor has an interior surface disposed in the bore that defines an orifice having a cross-sectional dimension that is less than a cross-sectional dimension of the channel such that the orifice can restrict a flow of fluid as the fluid flows between the housing inlet and outlet. The rotatable body is rotatable between 1) a first orientation, where the bore outlet is offset from the bore inlet along the fluid flow direction, and 2) a second orientation, where the bore inlet is offset from the bore outlet along the fluid flow direction.

A cooling system for a battery module, said cooling system including: at least one flow tube adapted to receive a cooling fluid, wherein a material of the at least one flow tube is a polymer-based material, and a member attached on an inner wall of at least a part of the at least one flow tube, wherein a material of the member is a metal, said member being sized such as to reduce the flow of the cooling fluid through the at least one flow tube to thereby achieve a balanced flow.

An improved flow conduit with gradually expanding caliber is described, where the conduit radius r grows with conduit length 1 so that the conductance remains constant or r.sup.4/l is constant, or alternatively, where the flow is near constant conductance flow, where or r.sup.n/l is constant, where n>4. The radius can expand over a portion of the conduit.

An apparatus and method for use in determining one or more fluid flow properties of a fluid in a conduit is disclosed. The apparatus includes a substrate including a barrier, a first flow sensor coupled to the substrate and a second flow sensor coupled to the substrate. The first flow sensor is located at a first sensor distance from a first barrier surface, and the second flow sensor is located a second sensor distance from the second barrier surface. The first sensor distance is substantially equal to the second sensor distance. In operation, the first flow sensor produces a first sensor signal, and the second flow sensor produces a second sensor signal. The direction of flow for the fluid is determined by comparing the first sensor signal to the second sensor signal.

A device that serves to increase the pressure on the outlets of water intakes in houses or gardens. This system to increase the water pressure is called salt-cellar-like device for increasing pressure. The salt-cellar-like device for increasing pressure has 6 external walls that give its body a hexagonal shape. These external walls allow the device to be held firmly by some tool that rotates the device, so that it is correctly inserted and attached to some water intake. The salt-cellar-like device for increasing pressure has a head that has a circular concavity on its upper part, as well as on the surface of this circular concavity there is an arrangement of conduits from which the water leaves the device to a higher pressure.

A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept latterly toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is latterly offset from the longitudinal axis. The interior end of the inducer body has a concave curvature. The swept flow passage and the curved interior end induce a vortex flow in a fluid flowing through the flow passage as it exits the flow passage and into a flow passage of a conduit the that extends at an angle relative to the longitudinal axis of the inducer body.
