Abstract
A theoretical model was developed for the dynamics and deposition pattern from gravity currents generated by axisymmetric particle-laden plumes. This model incorporates the interaction between the particles in the environment and the continuing plume. This interaction plays a central role in the evolution of the behavior of the plume and on the sedimentation patterns on the surrounding floor. Theoretical predictions for the deposition patterns were successfully compared with data from laboratory experiments for environments of both infinite and finite lateral extent. The evolution of the particle concentration in the environment and in the surface current until steady state is attained was also examined. A simple analytical expression is proposed for the sedimentation rate on the ground in the case of dilute plumes. The application of these new results to estimate the patterns of sedimentation from industrial chimney emissions is also discussed.
