Abstract
It is shown that the gravity-induced collision frequency of non-Brownian particles dispersed in a quiescent viscoplastic liquid is strongly dependent on the yield stress. The reduction in collision frequency with the increase in yield stress is due to the decrease in particle sedimentation velocity as well as the immobilization of smaller particles.
