Abstract
The computer automated radioactive particle tracking (CARPT) is a non-invasive flow monitoring technique used! for measuring mean and fluctuating velocity fields of a traced phase in a multiphase flow system. The method involves accurately monitoring the instantaneous position of a radioactive tracer particle using an array of strategically positioned scintillation detectors. A limitation to the accuracy of CARPT lies in the error associated with the reconstruction of the tracer particle position which affects the space-resolution of the technique. It is of interest, therefore, to minimize this error by choosing wisely the best hardware and an optimal configuration of CARPT detectors’ array. Such choices are currently based on experience, without firm scientific basis. In this paper, through theoretical modeling and simulation, we describe how the accuracy of a radioactive particle tracking setup may be assessed a priori. Through an example of a proposed implementation of CARPT on a gas- solids riser, we demonstrate how this knowledge can be used for choosing the hardware required for the experiment. Finally, we show how the optimal arrangement of detectors can be effected for maximum accuracy for a given amount of monetary investment for the experiment.
