Gravity-driven flux of particles through apertures
Ram Sudhir Sharma, Alexandre Leonelli, Kevin Zhao +2
The gravity-driven discharge of granular material through an aperture is a fundamental problem in granular physics and is classically described by empirical laws with different fit…
Experimental models for cohesive granular materials: a review
Ram Sudhir Sharma, Alban Sauret
Granular materials are involved in most industrial and environmental processes, as well as many civil engineering applications. Although significant advances have been made in unde…
The effects of interparticle cohesion on the collapse of granular columns
Ram Sudhir Sharma, Wladimir Sarlin, Langqi Xing +3
The presence of interparticle cohesion can drastically change the behavior of granular materials. For instance, powders are challenging to handle, and one can make a sandcastle usi…
Erosion of cohesive grains by an impinging turbulent jet
Ram Sudhir Sharma, Mingze Gong, Sivar Azadi +3
The erosion and transport of particles by an impinging turbulent jet in air is observed in various situations, such as the cleaning of a surface or during the landing of a spacecra…
Alcove formation in dissolving cliffs driven by density inversion instability
Ram Sudhir Sharma, Michael Berhanu, Arshad Kudrolli
We demonstrate conditions that give rise to cave-like features commonly found in dissolving cliffsides with a minimal two-phase physical model. Alcoves that are wider at the top an…
Unstable invasion of sedimenting granular suspensions
Arshad Kudrolli, Rausan Jewel, Ram Sudhir Sharma +1
We investigate the development of mobility inversion and fingering when a granular suspension is injected radially between horizontal parallel plates of a cell filled with a miscib…
