Tuning Andreev reflection at Graphene - superconductor junction: from zero field to quantum Hall regime
Andreev reflection (AR) is the underlying phenomena that determines the quasiparticle dynamics at the junction of a superconductor with any non-superconducting material, which in turn determines the transport properties ... -
Tuning crystal structures with weak interactions: From solid solutions to stoichiometric cocrystals
This thesis shows that when two organic compounds A and B are cocrystallized and the A∙∙∙B interactions are neither completely isotropic nor anisotropic enough to cause the formation of a stoichiometric cocrystal AxBy, ... -
Tuning Electronic Properties of Low Dimensional Materials
(2017-11-22)Discovery of grapheme has paved way for experimental realization of many physical phenomena such as massless Dirac fermions, quantum hall effect and zero-field conductivity. Search for other two dimensional (2D) materials ... -
Tuning of electrical and magnetic properties in nanocomposites of conductive LaNiO3 and transition metal oxides
The discovery of new composites by integrating materials of different physical properties with optimal control is of immense interest to researchers at present. Today, there are several composites being used for several ... -
Tuning of Multi-Band Power System Stabilizers in Multi-Machine Power Systems
Intermittent nature of renewables acts as a frequent trigger for small signal oscillations in power grid. These oscillatory modes correspond to either the rotor modes associated with the synchronous machines of conventional ... -
Tuning of Spin Reorientation and Compensation Transitions in Ferrites
Ferrites have attracted the attention of scientists and engineers in the last few years because of a combination of ferrimagnetic and insulating character. This makes them suitable for high frequency devices in telecommunication ... -
Tuning the electrical and thermoelectric properties of bilayer graphene by band engineering
Graphene and its two dimensional (2D) analogues have sustained the interests of the researchers for quite some time because of the rich physics they offer including many quantum phenomena and non-trivial topological ... -
Tuning Zinc Oxide Layers Towards White Light Emission
(2014-06-09)White light emitting diodes (LED) have drawn increasing attention due to their low energy consumption, high efficiency and potential to become primary lighting source by replacing conventional light sources. White light ... -
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 ... -
Turbulence Modeling for Predicting Flow Separation in Rocket Nozzles
(2018-01-30)Convergent-Divergent (C-D) nozzles are used in rocket engines to produce thrust as a reaction to the acceleration of hot combustion chamber gases in the opposite direction. To maximize the engine performance at high ... -
Turbulence-Premixed Flame Interactions
The interaction between premixed flames and turbulence is an inherently non-linear phenomenon. Understanding such interactions has profound practical implications towards the development of better combustion devices and ... -
Turbulent Free Convection Over Horizontal Surfaces
This thesis deals with turbulent free convection in a horizontal fluid layer above a heated surface. The work can be roughly divided into two parts. In the &st part a model is proposed for the near wall dynamics in ... -
Turbulent Free Moist Convection over Horizontal Surfaces
The heat and moisture loss from water surfaces are important in many natural and industrial systems. For example, the natural water cycle where water evaporates from the lakes, rivers, and seas, rises in the atmosphere, ... -
Turbulent Jet Diffusion Flame : Studies On Lliftoff, Stabilization And Autoignition
(2010-07-09)This thesis is concerned with investigations on two related issues of turbulent jet diffusion flame, namely (a) stabilization at liftoff and (b) autoignition in a turbulent jet diffusion flame. The approach of Conditional ... -
Turbulent Mixed Convection
(Indian Institute of Science, 2006-08-28)Turbulent mixed convection is a complicated flow where the buoyancy and shear forces compete with each other in affecting the flow dynamics. This thesis deals with the near wall dynamics in a turbulent mixed convection ... -
Turbulent Mixing of Multiple-Passive-Scalars
We have studied the mixing of multiple forced passive scalars in 3D homogeneous and isotropic turbulence. The trends of the structure functions for a single scalar, although not very well resolved, seem to be similar to ... -
Turbulent Near Wake Behind An Infinitely Yawed Flat Plate
(Indian Institute of Science, 2005-09-20)Near wake is the region of wake flow just behind the trailing edge of the body where the flow is strongly influenced by the upstream flow conditions and also perhaps by the characteristics of the body. The present work ... -
Two Dimensional Numerical Modelling Of Variably Saturated Flows
(Indian Institute of Science, 2007-02-21)The prediction of moisture and contaminant transport through unsaturated soil to ground water is becoming increasingly important in the fields of hydrology, agriculture and environmental engineering. Computer aided simulation ...
