Study Of Gas-Liquid Flow Behaviour In Raceway Zone Under Pulverised Coal Injection
(2011-02-09)Gas, liquid and powder flow in the lower part of a blast furnace is complex phenomena. In order to understand the aerodynamics of the blast furnace properly, these phenomena must be included in their advanced form. Previous ... -
Grain Boundary Processes In High Temperature Densification And Deformation Of Nanocrystalline Zirconia
(2011-02-08)Grain boundary processes play a major role in controlling different rate processes in yttria stabilized tetragonal zirconia. The present study concentrated on rate processes in tetragonal zirconia, which were significantly ... -
Understanding Knowledge Needs And Processes In Design
(2011-01-31)In this knowledge economy, organizations are leveraging their competence through the knowledge they possess. Managing knowledge will potentially retain the competence held by the organization if knowledge generated across ... -
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 ... -
Non-Linear Finite Element Analysis Using Strain-Space Plasticity Coupled With Damage
(2011-01-27)The Thesis deals with Strain-Space Plasticity and its implementation in Nonlinear Finite Element frame-work coupled with damage. Conventional Stress-Space Plasticity, though very popular amongst commercial nonlinear FEM ... -
Investigations Of Polymer Grafted Lipid Bilayers Using Dissipative Particle Dynamics
(2011-01-25)Lipid molecules are amphiphilic in nature consisting of a hydrophilic head group and hydrophobic hydrocarbon tails. The lipid bilayer consists of two layers of lipid molecules arranged with their hydrophobic tails facing ... -
Construction of 3D CAD Models From 2D Orthographic Views
(2011-01-19)This thesis addresses the problem of constructing 3D CAD models from 2D engineering drawings of the object. Procedures for each step in the popular bottom-up approach are described. In each of the steps in this approach, ... -
Kinematic And Static Analysis Of Over-Constrained Mechanisms And Deployable Pantograph Masts
(2011-01-19)Foldable and deployable space structures refer to a broad category of pre-fabricated structures that can be transformed from a compact folded configuration to a predetermined expanded configuration. Such deployable structures ... -
Finite Element And Experimental Studies On Fracture Behavior Of Bulk Metallic Glasses
(2011-01-19)The objective of this thesis is to study the fracture behavior of bulk metallic glasses. For this purpose, detailed finite element investigation of the mode I and mixed mode (I and II) stationary crack tip fields under ... -
Cloud Properties Over SHAR Region Derived From Weather RADAR Data
(2011-01-18)Weather radars are increasingly used for the study of clouds, understanding the precipitation systems and also for forecasting very short range weather (one hour to a few hours). Now, Doppler Weather Radar (DWR) data are ... -
Cylindrical Fretting And Delamination : Axisymmetric Static And Dynamic Analysis
(2011-01-17)Axisymmetric analysis of cylindrical contacts is considered in the context of axisymmetric assemblies such as shrink-fits. Fretting fatigue induces sub-critical cracks along the contact interface of press fits especially ... -
Demonstration Of Supersonic Combustion In A Combustion Driven Shock-Tunnel
(2011-01-17)For flights beyond Mach 6 ramjets are inefficient engines due to huge total pressure loss in the normal shock systems, combustion conditions that lose a large fraction of the available chemical energy due to dissociation ... -
Fuzzy Dynamic Wave Models For Flow Routing And Flow Control In Open Channels
(2011-01-10)The dynamic wave model (the complete form of the saint-Venant equations), as applied to flow routing in irrigation canals or flood routing in natural channels, is associated with parameter and model uncertainties. The ... -
Steady State Dynamics Of Systems With Fractional Order Derivative Damping Models
(2011-01-10)Rubber like materials find wide applications in damping treatment of structures, vibration isolations and they appear prominently in the form of hoses in many structures such as aircraft engines. The study reported in this ... -
