Surface morphology and shear effect on lubricated granular system
Ravindra S. Ghodake, Ashish V. Orpe
Improving the particle surface frictional behavior is of considerable importance in several industries so as to manipulate the powder flowability and handling. In this work, we hav…
Surface coating induced lubrication in flowing granular materials
Sayali V. Chaudhary, Ashish V. Orpe
We investigate the flow of spherical, bulk granular particles down an inclined plane mixed with small-sized spherical lubricant particles using discrete element method simulations.…
Structure-Dynamics Correlation and Its Link to Fragility and Dynamic Heterogeneity
Mohit Sharma, Srikanth Sastry, Sarika Maitra Bhattacharyya
Understanding the connection between structure, dynamics, and fragility, the rate at which the relaxation time grows with decreasing temperature, is central to unravelling the glas…
Flow and clogging behavior of a mixture of particles in a silo
Sukhada C. Bhure, Pankaj Doshi, Ashish V. Orpe
We investigated the clogging behavior observed during the flow of aspherical particles from a silo in the presence of spherical particles of different sizes and proportions using f…
Rigidity of Epithelial Tissues as a Double Optimization Problem
Sadjad Arzash, Indrajit Tah, Andrea J. Liu +1
How do cells tune emergent properties at the scale of tissues? One class of such emergent behaviors are rigidity transitions, in which a tissue changes from a solid-like to a fluid…
Dynamic heterogeneity in polydisperse systems: A comparative study of the role of local structural order parameter and particle size
Palak Patel, Mohit Sharma, Sarika Maitra Bhattacharyya
In polydisperse systems, describing the structure and any structural order parameter (SOP) is not trivial as it varies with the number of species we use to describe the system, M .…
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…
Thermodynamics and its correlation with dynamics in a mean-field model and pinned systems: A comparative study using two different methods of entropy calculation
Ujjwal Kumar Nandi, Palak Patel, Mohd Moid +6
Recently, some of us developed a novel model glass-forming liquid with k extra interactions with pseudo neighbours to each liquid particle over and above the regular interactions w…
Identifying structural signature of dynamical heterogeneity via the local softness parameter
Mohit Sharma, Manoj Kumar Nandi, Sarika Maitra Bhattacharyya
In a recent study by some of us, we have proposed a new measure of the structure of a liquid, the softness of the mean-field caging potential, and shown that it can describe the te…
Effective structure of a system with continuous polydispersity
Palak Patel, Manoj Kumar Nandi, Ujjwal Kumar Nandi +1
In a system of N particles, with continuous size polydispersity there exists N(N-1) number of partial structure factors making it analytically less tractable. A common practice is…
Microstructure and yielding of capillary force induced gel
Sameer Huprikar, Saurabh Usgaonkar, Ashish K. Lele +1
We have investigated the rheology and structure of a gel formed from a mixture of non-Brownian particles and two immiscible liquids. The suspension of particles in a liquid undergo…
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…
