Flow of lubricated granular material on an inclined plane
Ravindra S. Ghodake, Pankaj Doshi, Ashish V. Orpe
We have studied the gravity driven flow of spherical shaped, millimetric sized granular material coated with aspherical, micron-sized, near frictionless lubricant particles. Experi…
On the utility of cloth facemasks for controlling ejecta during respiratory events
Vivek Kumar, Sravankumar Nallamothu, Sourabh Shrivastava +5
The utility of wearing simple cloth face masks is analyzed using computational fluid dynamics simulations. We simulate the aerodynamic flow through the mask and the spatial spread…
Friction-mediated flow and jamming in a two-dimensional silo with two exit orifices
Ashish V. Orpe, Pankaj Doshi
We show that the interparticle friction coefficient significantly influences the flow and jamming behavior of granular materials exiting through the orifice of a two-dimensional si…
Fingering instability of a suspension film spreading on a spinning disk
Mayuresh Kulkarni, Subhadarshinee Sahoo, Pankaj Doshi +1
The spreading of a thin film of suspension on a spinning disk and the accompanying contact line instability is studied through flow visualization experiments. The critical radius f…
Flow of granular matter in a silo with multiple exit orifices: Jamming to mixing
Sandesh Deshmukh, Amit Kunte, Pankaj Doshi +1
We investigate the mixing characteristics of dry granular material while draining down a silo with multiple exit orifices. The mixing in the silo, which otherwise consists of nonin…
Spontaneous jamming and unjamming in a hopper with multiple exit orifices
Amit Kunte, Pankaj Doshi, Ashish V. Orpe
We show that the flow of granular material inside a 2-dimensional flat bottomed hopper is altered significantly by having more than one exit orifice. For the hoppers with small ori…
