Area-Based Concentration Measurement Using Optical Tomography Technique For Various Flow Patterns

Abstract

The Common Application For Process Tomography Is To Visualize Cross-Sectional Images Of Multi-Phase Flow System Such As Solid/Gas, Gas/Liquid And Water/Oil. The Flow Pattern Of The Flow System Will Directly Influence The Concentration Measurement. The Main Purpose Of This Paper Is To Investigate Various Flow Patterns Using Optical Tomography. The Optical Tomography Sensor In The Measurement System Is Constructed By Using Four Parallel Beam Projections Using Infrared Light Source In 85 Mm Inner Diameter Pipeline. Sensor Modeling And Reconstruction Algorithm Are Discussed. The Measurement Results Are Analyzed And Conclusion Is Made To Note Which Kind Of Flow Pattern Is Suitable To Be Measured By Optical Tomography.
