Mixing hi monosized particles and binary mixtures of solids in three-phase fluidized beds is investigated by means of a non-invasive Radioactive Particle Tracking technique (RPT). Pulses of particles at different column heights are constructed from the trajectory of a single radioactive tracer whose
## Ah&act -Solids mixing in fluidized beds has traditionally been treated using empirical transfer or diffusion coefficients. This study presents a new approach. A hyperbolic diiusion equation is derived by linearizing two phase flow equations of motion obtained previously by minimizing the rate o
