Abstract
THE STUDY OF PARTICULATE FORMATION AND DYNAMICS OF MOTION IN INDUSTRIAL MULTICOMPONENT SYSTEMS HAS BEEN HINDERED BY LACK OF EXPERIMENTAL DATA. TWO IN-SITU OPTICAL TECHNIQUES ARE PROPOSED HERE FOR ON-LINE CHARACTERIZATION OF THE SIZE DISTRIBUTION, VELOCITY AND THE NUMBER DENSITY OF ENTRAINED PARTICULATES IN TWO-PHASE FLOWS. THE PROPOSED TECHNIQUES: POLARIZATION INTENSITY RATIO (PIR) AND POINTER BEAM (PB) COVER THE DYNAMIC RANGE OF INTEREST WITH HIGH SPATIAL AND TEMPORAL RESOLUTIONS. PIR TECHNIQUE HAS THE ABILITY OF MEASURING SINGLE OR ENSEMBLE PARTICLE SIZES IN THE RANGD IS LESSER THAN OR GREATER THAN 0.01 UM. MEASUREMENTS OF SINGLE PARTICLE SIZE AND VELOCITY ARE ACHIEVED BY THE PB METHOD IN THE RANGE D IS LESSER THAN OR GREATER THAN 0.1 UM. IT IS EXPECTED UNDER THIS PROGRAM TO DEVELOP AN ANALYTICAL APPROACH USING THE LORENTZ-MIE THEORY,AND TO EXPERIMENTALLY EVALUATE THE TWO TECHNIQUES WITH ADVANCED OPTICAL INSTRUMENTATION.
