Data associated with 'Impinging jet erosion of granular sediments'

Data relating to the study of the erosion behaviour and modelling of glass particle beds under impinging jet conditions. The study focuses on particle size effects and the onset of erosion. Ultrasonic profiling was implemented to scan and measure crater profiles. The results indicate that particle size largely affects crater dimensions and erosion behaviour. The standard erosion parameter works well for modelling cohesionless particles down to a certain size limit, beyond which cohesive forces become significant. A new parameter, Eτ, based on particle critical shear stress, is introduced for erosion modelling. The transition to cohesive behaviour observed in the smallest glass particles is successfully accounted for using Eτ.
