Both the Hausner Ratio and Carr Index reduce bulk and tapped density to a single number. The mechanism behind that number, whether aeration, particle shape, or surface cohesion, determines whether it supports a process decision or actively misleads one.
Temperature shifts surface energy, contact compliance, and residual moisture state in ways that can reverse a powder's ambient flow behavior. This Insight explains the dominant mechanisms across three temperature ranges and what elevated-temperature testing reveals for SLS powder beds, spray dryer outlets, and heated conveying systems.
