Abstract :
The objective of this paper is to present research on the use of an optical tomography method using infra-red sensors for real-time monitoring of solid particles conveyed by a gravity flow rig. The sensor comprised two orthogonal and two diagonal light projections to form upstream and downstream arrays in a total of four parallel projections. Collimating the radiated beam from a light source and passing it through a flow regime ensures that the intensity of radiation detected on the opposite side is linked to the distribution and the absorption coefficients of the different phases in the path of the beam. The information on the flow captured using upstream and downstream infra-red sensors is digitized by the DAS system before it was passed into a computer to be analyzed in order to reconstruct the cross section image. This investigation successfully developed and tested an infra-red tomography system to profile the concentration of two phase flow in a gravity flow rig.
