Tribology Of An Etched Near-Eutectic Aluminium-Silicon Alloy Sliding Against A Steel Counterface
(2013-05-01)Lightweight aluminium-silicon alloy is an attractive material for making engine cylinders in automobiles. It imparts good power to weight ratio to the engine. High silicon containing aluminium alloys are used in current ... -
Tribology Of Combustion Generated Soot
(2016-11-19)Soot is a carbonaceous materials produced as a result of incomplete combustion of fuels (gasoline, diesel, etc). At the present level of automobile technology, emission of soot from combustion in diesel engine appears to ... -
A Tropical Survey of Mid-Tropospheric Cyclones, their Classification and Genesis over the Arabian Sea
Middle Tropospheric Cyclones (MTCs) are moist synoptic tropical systems with vorticity maxima in the middle troposphere and weak signature in the lower troposphere. We begin with a tropical survey of MTCs; in South Asia, ... -
Tropical Teleconnections to the Indian Summer Monsoon in Observations and in a Coupled Model
An accurate seasonal prediction of Indian summer monsoon rainfall (ISMR) holds immense importance for the socio-economic well-being of South-Asian countries, as it directly impacts agricultural output and overall economies. ... -
Tufting of carbon fibre/epoxy composites for improved damage tolerance
Laminated composite structures are susceptible to delamination and debonding during their service life due to their poor out-of-plane interlamellar properties. Such damage can occur either during manufacturing or during ... -
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 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 ... -

Two Inverse Problems In Linear Elasticity With Applications To Force-Sensing And Mechanical Characterization
(2013-06-24)Two inverse problems in elasticity are addressed with motivation from cellular biomechanics. The first application is computation of holding forces on a cell during its manipulation and the second application is estimation ... -
Two Problems on the Parametric Resonances and Bifurcations in Rotating Beams
The current research work addresses two interesting systems related to rotating beams. The first dynamical system under consideration is an articulated uniform beam rotating in vacuum under vertical hub excitation along ... -
Two-temperature thermodynamics and continuum modelling of viscoplaticity in metals
In recent years, numerous studies have shown the complexity of plastic deformation in metals. The accuracy in modelling inelastic behaviour holds great significance for engineers as metals and metallic alloys are extensively ... -
UAV Group Autonomy In Network Centric Environment
(2016-11-23)It is a well-recognized fact that unmanned aerial vehicles are an essential element in today’s network-centric integrated battlefield environment. Compared to solo UAV missions, multiple unmanned aerial vehicles deployed ...
