Nanoparticles for Bio-Imaging : Magnetic Resonance Imaging and Fluorescence Imaging
(2018-07-19)This thesis provides several nanomaterial systems that can be used as contrast agents in magnetic resonance imaging (MRI) and for optical fluorescence imaging. Nanoparticle systems described in this thesis fall under three ... -
Transition and Acoustic Response of Vortex Breakdown Modes in Unconfined Coaxial Swirling Flow and Flame
(2018-07-19)The efficient and enhanced mixing of heat and incoming reactants is achieved in modern gas turbine systems by employing swirling flows. This is realized by a low velocity region (internal recirculation zone -IRZ) zone ... -
Motion Space Analysis of Smooth Objects in Point Contacts
(2018-07-19)The present work studies instantaneous motion of smooth planar and spatial objects in unilateral point contacts. The traditional first-order instantaneous kinematic analysis is found insufficient to explain many common ... -
Experimental Analysis of Shock Stand off Distance over Spherical Bodies in Hypersonic Flows
(2018-07-18)One of the characteristics of the high speed ows over blunt bodies is the detached shock formed in front of the body. The distance of the shock from the stagnation point measured along the stagnation streamline is termed ... -
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 ... -
Swelling and Dye Adsorption Characteristics of Superabsorbent Polymers
(2018-07-18)In the current study, SAPs of cationic monomer [2 - (Methacryloyloxy) ethyl] trimethylammonium chloride have been prepared by free radical solution polymerisation with different crosslinkers. They were subjected to repeated ... -
Static and Dynamic Behavior of Reinforced Masonry : Experimental and Analytical Investigations
(2018-07-18)The most common form of dwellings in rural and semi-urban areas of India and other developing countries around the globe are one/two storey unreinforced masonry (URM) buildings. It is well known that such masonry buildings ... -
Evaluation of the Engineering Properties of Municipal Solid Waste for Landfill Design
(2018-07-18)The objective of this thesis is to evaluate the engineering properties of Municipal Solid Waste (MSW) that are necessary in the design of landfills. The engineering properties of MSW such as compressibility, shear strength, ... -
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ... -
Analysis and Modelling of Activity-Travel Behaviour of Non-Workers from an Indian City
(2018-07-16)Indian cities have been witnessing rapid transformation due to the synergistic effect of industrialisation, flourishing-economy, motorisation, population explosion, and migration. The alarming increase in travel demand as ... -
Effect of Favourable Pressure Gradient on Turbulence in Boundary Layers
(2018-07-16)This thesis explores the effects of favourable pressure gradient on the structure of turbulent boundary layers (TBL). In this context, the structure of three types of boundary layers namely a zero-pressure-gradient ... -
An Integrated Estimation-Guidance Approach for Seeker-less Interceptors
(2018-07-16)In this thesis, the problem of intercepting highly manoeuvrable threats using seeker-less interceptors that operate in the command guidance mode, is addressed. These systems are more prone to estimation errors than standard ... -
Insights into Instabilities in Burning and Acoustically Levitated Nanofluid Droplets
(2018-07-16)The complex multiscale physics of nanoparticle laden functional droplets in a reacting environment is of fundamental and applied significance for a wide variety of applications ranging from thermal sprays to pharmaceutics ... -
Role of Microstructure in the Mechanics of Soft Matter
(2018-07-16)Materials which exhibit non-linear mechanical behaviors under large deformations are generally classified as “soft matter”. Elastomers represent an important class of soft materials which have wide commercial applications ... -
