A dynamic fluid flow control structure is provided that allows precise control over fluid flow using a series of two or more orifices, at least one of which may be reconfigured to change its flow characteristics. A flood control system and a flood control process are provided that emulate a preset discharge profile over time. Some versions of the structure, process, and system can be used to provide controlled storm discharge patterns in a developed area that emulate the natural pre-development discharge patterns.

Material flow amplifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion and head losses) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile (e.g., increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like).

The invention provides method and system of controlling flow rate in a pipeline network for fluids. The system includes a demand management system to monitor fluid flow rate in the pipeline network (10) and a pump (34) to increase the fluid flow rate when the demand management system determines an increase in fluid flow rate is required.

A pulsation dampener system is provided. The pulsation dampener system includes a pump that pumps fluid through the pulsation dampener system. A pulsation dampener is located downstream from the pump and dampens pulsations within the fluid. A pressure sensor is located downstream from the pump and detects a pump pressure of the fluid at the pulsation dampener. A wye pipe located downstream of the pulsation dampener and the pressure sensor that diverts the fluid into two or more flow paths. From the wye, a first flow path increases pump pressure of the fluid and a second flow path allows the fluid to flow unrestricted. Piping receives the fluid from the first flow path and the second flow path and discharges the fluid further downstream.
