Analysis of the Flow of Granular Materials through a Screw Conveyor
Screw conveyors are widely employed in industry for the bulk transport of particulate materials. Several studies have attempted to correlate the discharge rate with the rotation speed of the screw via experiments and ... -
Computational Study of Stokesian Suspensions using Particle Mesh Ewald Summation
(2018-07-18)We consider fast computation methods for simulation of dynamics of a collection of particles dispersed in an unbounded Stokesian suspension. Stokesian suspensions are of great practical interest in the manufacturing and ... -
Dynamics and Rheology of Non-colloidal Suspensions: Active and Soft Deformable Particles
Classical works on the suspensions of rigid spherical and ellipsoidal particles have been carried out by Einstein and Jeffery. However, in nature and industry, we come across materials that are either deformable or active. ... -
Experimental study of the flow of granular media through a horizontal screw feeder system
A significant fraction of the materials handled in the chemical, food-processing, and pharmaceutical industries are particulate in nature. Screw feeder systems are often employed in such scenarios to achieve their bulk ... -
Flow and structure of dense granular materials
Granular materials are frequently encountered in our daily lives and are widely processed forms of matter in various industries. Despite decades of research, the mechanical behavior of granular materials is not well ... -
Micromechanical understanding of the macroscopic features of dense granular materials
The prevalence of granular materials in nature (soil, beach sand, rubble pile asteroids) and in several industries (cement, food grains, pharmaceutical powders) has motivated extensive research towards understanding the ... -
Refractive-Index-Matched Fluorescent Particle Image Velocimetry for Investigation of Flow in Immersed Granular Materials
Refractive-Index-Matched Fluorescent Particle Image Velocimetry for Investigation of Flow in Immersed Granular Materials The ubiquity of granular materials and their importance in everyday life, industry, and nature make ... -
Rheology of dense granular materials
Granular materials are frequently encountered in our daily lives and are widely used in several industrial processes. Characterising the flow of these materials has always proved challenging due to the lack of simple ... -
Rheology of dense non-Brownian suspensions
Suspensions are ubiquitous in nature and industry, ranging from magma, blood, and mud to cement, paint, and molten chocolate. Despite the Newtonian nature of the suspending fluid and the expectation of linearity in the ... -
Syngas Production by Methane Reforming and H2 Purification by CO Abatement over Transition Metal-Substituted Reducible Oxides
Methane and carbon dioxide are two major greenhouse gases, with CH4 having higher potency towards global warming. Several methods have been explored for transforming CH4 into higher value products, of which syngas production ... -
Synthesis of Monodispersed Pdms Microspheres of Tunable Modulus Using Droplet Microfluidics and Study of the Rheology of Dense Suspensions of Rigid and Soft Particles in Shear Flow
We report the synthesis of monodispersed PDMS microspheres of tuneable modulus using a droplet-based microfluidics approach. Nevertheless, polymer microspheres can be used as a model representative particle to mimic the ... -
Testing the Hypothesis of Quorum Sensing in Vibrio fischeri : Luminescence, Motility, and Biofilm
(2018-03-15)The individual behaviour of prokaryotic organisms such as bacteria often gives rise to complexity that is commonly associated with multicellular behaviour. The transition from unicellular to multicellular behaviour occurs ...
