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:

Bulk flow properties of hard and soft wheat flours
TL;DR: In this article, the authors compared the flow properties of soft white winter (SWW) and hard red winter (HRW) wheat flours and found that the wall friction angle for SWW flour was higher than that of HRW flour.

Flow abilities of powders and granular materials evidenced from dynamical tap density measurement
Karl Traina,Rudi Cloots,Sébastien Bontempi,Geoffroy Lumay,Nicolas Vandewalle,Frédéric Boschini +5 more
TL;DR: In this article, an overview of the flow properties of granular systems, including voids, granular porosity and random packing characteristics, is presented, where the concept of additional porous volume is introduced, defined as the additional air volume added to the optimal granular packing.

Manipulation and Characterization of a Novel Titanium Powder Precursor for Additive Manufacturing Applications
TL;DR: In this paper, a novel and inexpensive Ti sponge material was selected as a precursor and processed using a CSIRO proprietary powder manipulation technology (PMT), and the manipulated powder was characterized in terms of the particle size distribution, roundness, flowability in the Hall Funnel flowmeter, static angle of repose (AOR), apparent density and tap density.

Selective laser melting (SLM) of gold (Au)
TL;DR: In this paper, a full factorial approach was used to vary the processing parameters and identify suitable processing region for gold powder, and the effects of laser processing parameters on the internal porosity of the multi-layer parts were examined.
