Abstract
A noninvasive Computer Automated Radioactive Particle Tracking (CARPT) Facility is used for the investigation of liquid recirculation and turbulence in a bubble column. The motion of a single neutrally buoyant radioactive particle is monitored by an array of scintillation detectors and analyzed by an on-line computer to map the flow field. Results for the mean flow patterns and turbulence in a 12″ diameter column are reported for the air-water system. This communication marks the first application of CARPT for tracing the liquid flow in bubble columns.
