Powder flowability and density ratios: the impact of granules packing
TLDR
In this paper, a new flowability criterion based on a novel technique to determine a high packing density was proposed, which is more sensitive to differences in flowability, as quantified by the repose angle.About:

Technological Excipients of Tablets: Study of Flow Properties and Compaction Behavior
TL;DR: The obtained results demonstrated that the binary mixtures and the pure excipients showed similar flow properties, and the obtained tablets with the plastic excipient had lower values of exerted force by the upper punch and apparent net energy, and higher values of plasticity index and time periods of the force/time compression profiles.
