Dual optical fibre measurements of the particle concentration in gas/solid flows

Dual optical fibre measurements of the particle concentration in gas/solid flows Numerous optical probe designs to measure particle volume fraction have been proposed in the literature. Unfortunately, almost all of them suffer from an ill-defined measurement volume, poor sensitivity or require frequent and tedious calibration. We propose an improvement in the design of a dual optical fibre probe. It has a well-defined measuring volume and a near-linear sensitivity. A general calibration theory for optical fibre probes is also proposed. The design and the theory have been tested in a simple experimental set-up with encouraging results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

Numerous optical probe designs to measure particle volume fraction have been proposed in the literature. Unfortunately, almost all of them suffer from an ill-defined measurement volume, poor sensitivity or require frequent and tedious calibration. We propose an improvement in the design of a dual optical fibre probe. It has a well-defined measuring volume and a near-linear sensitivity. A general calibration theory for optical fibre probes is also proposed. The design and the theory have been tested in a simple experimental set-up with encouraging results.
