Benchmarking Radioactive Particle Tracking (RPT) with Laser Doppler Anemometry (LDA)

Abstract

Abstract In current work, Radioactive Particle Tracking (RPT) experiment has been performed in a rectangular bubble column having dimensions reported by Pfleger et al. (1999). As has been reported in recent decades, RPT has come to be accepted now as a reliable and versatile non-invasive flow measurement technique for mapping the flow fields in multiphase reactors.In this work, the objective has been to benchmark RPT (which is a very versatile technique) against reported data (Pfleger et al. 1999) with Laser Doppler Anemometry (LDA) (which is claimed to be a very accurate technique at low volume fractions of the dispersed phase). We show that RPT does remarkably well both in terms of versatility and accuracy. Overall, this work helps to establish the accuracy standards of the RPT technique.
