MEASUREMENT OF GAS VOLUMETRIC FLOW RATE IN GAS/LIQUID MIXTURES USING OPTICAL TOMOGRAPHY : MATHEMATICAL MODELLING

摘要

25 MEASUREMENT OF GAS VOLUMETRIC FLOW RATE IN GAS/LIQUID MIXTURES USING OPTICAL TOMOGRAPHY ABSTRACT THE PRESENT INVENTION PROVIDES A METHOD OF MEASURING GAS VOLURNETRIC FLOW RATE IN 5 GAS/LIQUID MIXTURES THROUGH A FIG HAVING A PLURALITY OF OPTICAL SENSORS. THE METHOD COMPRISES RECORDING OUTPUTS FROM THE OPTICAL SENSORS WHEN THE GAS/LIQUID MIXTURES IS NOT FLOWING TO PROVIDE AN AVERAGE NOISE OUTPUT AS A REFERENCE; AMPLIFYING THE OUTPUT SIGNALS; ESTIMATING ATTENUATION COEFFICIENT DISTRIBUTION ACROSS THE MEASUREMENT SECTION; AND DISPLAYING COEFFICIENTS IS TORNOGRAMS. 1 0 MOST ILLUSTRATIVE DRAWING: FIG. 13
