Embodiment Construction

[0016] Embodiments of the present invention provide systems and methods for inferring the average velocity of a flowing fluid mixture from observed concentrations of reactive components of the fluid. In many real-world fluid handling systems, the volumetric flow rate of a fluid and the concentration of one or more components of the fluid are of interest. Conventionally, flow rates and component concentrations are estimated individually by separate, dedicated measurement devices. By inferring fluid flow rates from observed concentrations of reactive components of the fluid, embodiments of the present invention provide an estimate of volumetric flow rate that does not require dedicated flow measurement equipment.

[0017] Embodiments provide a method for estimating the velocity of a flowing fluid. A prerequisite for this method requires that the fluid include constituent species that undergo chemical reactions in the system of interest. The method includes collecting observati...

Abstract

A method for estimating a fluid flow velocity may include receiving, with a processing device, a plurality of observations corresponding to a concentration of a constituent of a flowing fluid mixture, and computing a final estimate of an average velocity of the flowing fluid mixture based at least in part on the observations, wherein the constituent is undergoing a chemical reaction and the computing implements a reactive transport model.

Description

technical field [0001] The present invention relates generally to fluid dynamics, and more particularly to estimating the average velocity of a flowing fluid mixture from observed concentrations of reactive components of the fluid. Background technique [0002] Various devices and methods are available for measuring the volumetric flow rate of fluids. Typical flow measurement devices include turbine meters, venturi meters, orifice meters, pressure drop meters, ultrasonic meters, and flumes, among others. Flow measurement devices are typically inserted into pipes or flow channels. Such invasive techniques are inconvenient and expensive. [0003] Some existing flow meters determine the flow rate of a fluid based on a comparison of the static pressure and the dynamic pressure of the fluid at a given location. Other flow meters are available that estimate the flow rate of a fluid based on the relationship between the temperature of the fluid and the kinematic viscosity of the...
