Abstract

We study the evolution of the compaction and acoustic properties of binary granular mixture during radial segregation. These parameters are indicators of how granular materials absorb, distribute and dissipate mechanical energy, which is possibly the primary form of energy that drive transport of the individual grains and pattern formation. The compaction and the sound spectra of the binary granular mixture inside a disc, which is rotating along axis, were measured during the transition from mixed state to segregated state. The peaks of the sound spectra changes but no trend can be inferred while the compaction decreased during the transition. Better understanding of the compaction and acoustic properties are important in describing and explaining phenomena that usually occur with radial segregation, such as the onset of axial segregation and axial band coarsening.
