Abstract
In some embodiments, an apparatus and a system, as well as a method and article, may operate to identify one or more multiphase fluid flow regimes as an output of fuzzy logic processing, with inputs to the fuzzy logic processing comprising a set of physical parameter values as attributes at a location in a fluid flow that are determined by at least one of measurement or simulation, and to operate a controlled device based on the output. Additional apparatus, systems, and methods are disclosed.
Claims39
A method comprising:
- identifying one or more fluid flow regimes as an output of fuzzy logic processing, with inputs to the fuzzy logic processing comprising a set of physical parameter values as attributes at a location in a fluid flow that are determined by at least one of measurement or simulation;
- and
- operating a controlled device based on the output.

A control system, comprising:
- at least one fluid parameter measurement device to provide a measured value of at least one attribute of a fluid or of the fluid's flow, at a location within a flow of the fluid;
- a processing unit to identify one or more fluid flow regimes as an output of fuzzy logic processing, with the measured value of the at least one attribute as an input to the fuzzy logic processing;
- and
- a controlled device to operate in response to at least one of the output, or to a pressure drop value accounting for proximity of nearby-neighboring regimes based on the output.
