Structural sensitivity of the precessing vortex core instability in swirled jets
This thesis performs an LES study of the flow through a swirling nozzle. The nozzle has one single stream with swirl being generated by vanes mounted on an axially aligned centrebody. The end face of the centrebody ... -
Structural, Ferroelectric, Piezoelectric and Phase Transition Studies of Lead Free (Na0.5Bi0.5)TiO3 Based Ceramics
(2018-04-23)Ferroelectric materials, especially the polycrystalline ceramics, are very promising material for a variety of applications such as high permittivity dielectrics, ferroelectric memories, piezoelectric sensors, piezoelect ... -
Structure and Dynamics of Fluids Under Nanoscale Confinement
Fluid molecules confined between solid surfaces separated by a few nanometers are of considerable interest in nanoscience and nanotechnology as they undergo structural and dynamical transitions absent in their corresponding ... -
Structure And Dynamics Of Interfacial And Confined Water
(2011-03-28)Understanding the structure and dynamics of molecularly thin films or the state of water confined to nanoscale dimensions is an active field of research and has wide applications in areas ranging from biology to geology. ... -
Structure and Dynamics of the Inter-tropical Convergence zones
(2018-08-13)The east-west oriented cloud bands in the tropics are called the Inter-tropical Con-vergence Zones (ITCZ). Till recently, the ITCZ has been assumed to have a simple vertical structure with convergence near the surface ... -
Structure Of Sink Flow Boundary Layers
(2011-03-17)The work reported in this thesis is an experimental and theoretical investigation of the so-called sink flow boundary layers. These are two-dimensional (in the mean), favourable-pressure-gradient (FPG) boundary layer flows ... -
Structure of the Tropical Easterly Jet in NCAR CAM-3.1 GCM
(2018-04-24)This thesis examines the structure of the Tropical Easterly Jet (TEJ) in a General Circulation Model (GCM). The TEJ is observed only during the Indian summer monsoon period and is strongest during July and August. The jet ... -
Structure of Turbulent, Swirling Round Jets
The present study deals with the numerical analysis of the effect of the swirl in the self-preservation region of the turbulent round jet. However, a large number of literature exists for the analysis of near-exit regions—very ... -
Structure property correlation studies on Ca-modified Ba(Ti, Zr/Sn)O3 piezoceramics
In this thesis we have investigated the structure, property correlation of the lead-free piezoelectric ceramic of (Ba,Ca) (Ti,Zr/Sn)O3 system. A self-consistent set of experimental techniques such as X-ray powder diffraction, ... -
Structure, Microstructure and Magnetic Properties of Fe-Ga and R-Fe based Magnetostrictive Thin Films
(2018-02-27)Magnetostrictive materials belong to an important class of smart magnetic materials which have potential applications as ultrasonic transducers, sensors, actuators, delay lines, energy harvesting devices etc. Although, ... -
Structure-Property Correlation in Additively Manufactured High-Temperature Materials: Insights from Nickel-Based Superalloy IN718 & Nickel-Based Eutectic High Entropy Alloy AlCoCrFeNi2.1
High-temperature alloys are technically very important materials that possess higher resistance toward mechanical and chemical degradation at 0.4-0.6 TM for a constant/cyclic load. These attributes make them candidate ... -
Structure-Property Correlation in Binary Immiscible Polymer Blends Compatibilized by Mutually Miscible Homopolymer and Carbonaceous Nanoparticles
The thesis systematically studies the various morphology, mechanical properties, crystallization kinetics and compatibilization effects of homopolymers, carbonaceous nanoparticles such as multiwall carbon nanotubes (MWNTs), ... -
Structure-Property correlation in epoxy composites containing carbonaceous nanoparticles
Epoxy is widely used as thermosetting materials in carbon fiber composites due to its combined superior thermal and mechanical properties which makes them a potential candidate for myriad applications. But epoxy suffers ... -
Structures, Thermodynamics and Phase Relations in Selected Oxide Systems
(Indian Institute of Science, 2005-02-08)Understanding of the interrelationship between structure, thermodynamic properties and phase diagrams is very useful for rationalizing the behavior of materials and development of predictive models, which can be used to ... -
Studies for Design of Layered Ceramic Armour Inspired by Seashells
(2018-06-26)Pearly layers in seashells, also known as nacreous layers, are reported to be three orders of magnitude tougher than their primary constituent, aragonite. Their high toughness is attributed to a particular structure of ... -
