The development of a non-intrusive particle tracking system to follow the trajectory of an individual particle in three dimensions within a mass of particles is necessary to experimentally validate developing theories of inclined chute granular flows in conjunction with particle dynamics models. An understanding of the exact nature of such flows is of critical importance to a variety of industries concerned with solids handling, as well as in natural geological events. The tracking system, based on the principle of radiosonde'' transmitters coupled to receiving antennae by magnetic induction, is being developed. The radiosonde consists of one or more, orthogonally placed miniature circuits with integral loop antennas, mounted into a sphere of approximately 3/4 in. in diameter. The radiosonde sphere position can be traced during the flow down a chute by analyzing the induced voltage signals in the three or more external orthogonal receiving loop antennas due to the transmitter chips. 22 refs., 15 figs.
