Analysis Of Dense Sheared Granular Flows
(2011-01-27)A granular material is a collection of discrete, solid particles of macroscopic size dispersed in an interstitial fluid, in which the fluid has an insignificant effect on the particle dynamics. Because they exhibit fascinating ... -
Characterisation and Analysis of a Vibro-fluidised Granular Material
(Indian Institute of Science, 2006-12-12)The present work is concerned with the mathematical modelling of a bed of granular material in a gravitational field vertically fluidised by a vibrating surface. The particles are in rapid motion, and lose energy by inelastic ... -
Direct Numerical Simulations and Fluctuating Force Simulations of Turbulent Particle-gas Suspensions
(2018-05-18)Turbulent gas-particle suspensions are of great practical importance in many naturally phenomena, such as dust storms and snow avalanches, as well as in industrial applications such as fluidised, circulating bed reactors ... -
Formation of Porous Metallic Nanostructures Electrocatalytic Studies on Self-Assembled Au@Pt Nanoparticulate Films, and SERS Activity of Inkjet Printed Silver Substrates
(2018-04-24)Porous, conductive metallic nanostructures are required in several fields, such as energy conversion, low-cost sensors etc. This thesis reports on the development of an electrocatalytically active and conductive membrane ... -
Gravity flow of granular materials through a vertical channel
Grains and powders are the second most widely used materials in industries and daily life after simple fluids. There are a variety of granular materials such as food grains, detergents, tablets and capsules, fertilizers, ... -
Mesoscale Modelling of sheared lamellar mesophases
The lamellar phase or smectic lyotropic liquid crystalline medium, which is made up of alternating flat sheets of water and surfactant bilayers shearing past each other in an imposed flow. Surprisingly, In practical ... -
Multi-scale Modelling of Lamellar Mesophases
(2018-05-25)Surfactants are amphiphilic molecules which self-assemble at the interface in oil-water-surfactant mixtures such that the hydrophobic part, called tail, stays in oil and the remaining part, called head, resides in hydrophilic ... -
Particle Dynamics In A Turbulent Particle-Gas Suspension At High Stokes Number
(2010-12-08)Particle laden turbulent flows find applications in many industrial processes such as energy conversion, air pollution control etc. In these types of flows, there are strong coupling between the turbulent fluctuations in ... -
Rheology of Dense Granular Chute Flows
Granular flows have always fascinated researchers through its complex and mysterious behavior. Although a collection of solids, they exhibit properties like that of fluids. Flows over an inclined plane, known as chute flow, ... -
Studies In Stability Of Newtonian And Viscoelastic Fluid Flow Past Rigid And Flexible Surfaces
(2010-09-23)The surface oscillations in a deformable wall are known to induce an instability in the adjacent flow even in the absence of inertia. This instability, if understood properly, can be exploited to generate a well-mixed flow ... -
Turbulence in Soft Walled Micro Channels
(2017-12-07)In comparison to the flow in a rigid channel, there is a multi-fold reduction in the transition Reynolds number for the flow in a micro channel when one of the walls is made sufficiently soft, due to a dynamical instability ...
