A rectification member 32 is a rectification member that rectifies air that cools molten resin filaments discharged from a nozzle, including: a multi-cylindrical part in which a plurality of cylindrical cells 34a are formed; and a wire net 36 arranged to cover an opening part of the multi-cylindrical part. The wire net 36 has a mesh opening that is smaller than the size of the cylindrical cells 34a.

An improved arcuate sweep elbow pipe connector section having an increased flow capacity and is a replacement for conventional ninety degree elbows as part of the piping system used to deliver water from a source to a fire sprinkler head. The arcuate sweep elbow pipe connector section is integrally formed at one end with a first connecting section and integrally formed at a section end with a second connection section. The connecting sections are positioned ninety degrees relative to each other and the arcuate sweep elbow pipe connector section optimizes water flow through both connecting sections.

A phase power device, comprising: a circulation pipe (1) and a preset number of phase power control components (2), wherein the circulation pipe (1) is used to provide a channel for fluid circulation flow, and the preset number of phase power control components (2) are disposed on the circulation pipe (1) and used to drive fluid in the circulation pipe (1) to circulate and flow. Further provided is a fluid experiment system, comprising the phase power device. The phase power device and the fluid experiment system may enable the fluid to meet a set flow requirement during the experiment, thus reducing the use of auxiliary equipment, and reducing experiment costs.

Provided herein are components for a fluid network modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs.

The invention relates to a flow conditioner for conditioning a fluid flow comprising a pipe having a constriction with a reduced pipe cross-section, at least one ring-shaped element arranged inside the pipe which has an outer diameter which is smaller than the inner diameter of the pipe in the axial region of the pipe in which the at least one ring-shaped element is arranged, and having an areal web whose surface normal is not in parallel with the pipe axis. The invention further relates to a throughflow measurement system for measuring a fluid throughflow through a pipe having a measurement device and a flow conditioner in accordance with the invention arranged upstream of the measurement device.

An air cleaner includes a housing having an air inlet and an air outlet. The air cleaner further includes a filter media coupled to the housing and positioned between the air inlet and the air outlet, the filter media configured to filter an air flow that enters the housing through the air inlet and exits the housing through the air outlet. The air cleaner includes a rectifier coupled to the housing and positioned at a location downstream of the filter media, the rectifier including an outer ring that is orthogonally oriented with respect to the air flow.

A flow conditioning assembly comprising an integral elbow flow conditioner and a downstream flow conditioner. The elbow flow conditioner includes a pipe elbow with one or more flow conditioning elements. Each flow conditioning element includes one or more turning guides. Each turning guide is generally circular and radially spaced from one another and an inner surface of the elbow. Spaced vanes maintain the radial spacing of the turning guides. The vanes divide the radial space between the turning guides and pipe elbow into a plurality of flow channels that turn in generally the same direction as the inner surface of the pipe elbow. The downstream flow conditioner comprises a flow conditioning structure within a pipe element. The flow conditioning structure includes one or more flow guides of generally circular form radially spaced from one another and the pipe element. Spaced support vanes maintain the radial spacing of the flow guides.
