Abstract / Description:The modeling of particle dynamics requires accurate measurements of evolving particle size distributions. One technique for obtaining these dynamic measurements is through the use of chord length distributions obtained from laser backscattering. A model that captures the interactions between the measuring probe and the particle size distribution is proposed here. The interactions are determined not through first-principle modeling, but rather through an inverse problem approach that creates the model directly from a reference particle measurement technique. Once this calibration is performed, evolving particle size distributions can be measured dynamically online. An example system of glass beads in water is examined and some features and drawbacks of the technique are identified.
