The effects of other factors, such as particle shape and size distribution, on the flow dynamics of granular materials
Research gap analysis derived from 3 physics papers in our local library.
The gap
Future studies should investigate the effects of other factors, such as particle shape and size distribution, on the flow dynamics of granular materials. The research should be extended to other types of granular flows, such as those observed in landslides and industrial processes.
Evidence profile

ABSTRACT Geophysical mass flows of granular materials composed of irregular‐shaped particles with different frictions are ubiquitous in catastrophic events such as landslides, snow, and rock avalanches; however, their mobilities and deposition morphologies remain poorly understood.

Further studies are needed to investigate the effects of particle shape irregularity on the behavior of other types of granular materials. Experimental studies are needed to validate the findings of this simulation-based study. Further research is needed to develop more accurate constitutive models that capture the effects of particle shape irregularity.
