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 ... -

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 Player Game Variant Of The Erdos Szekeres Problem
(2014-08-01)The following problem has been known for its beauty and elementary character. The Erd˝os Szekeres problem[7]: For any integer k ≥ 3, determine if there exists a smallest positive integer N(k) such that any set of atleast ... -
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 ... -
A Two Step Optimal Decoding for PSK and Trellis Coded Modulation in Noisy Index Coding Problem
Index coding is a communication problem in which a server has a set of messages and wants to broadcast them to a set of receivers. Each receiver is interested in a single message, but some of the receivers may have some ... -
Two-dimensional layered materials integrated with oxide semiconductor-based hybrid devices for broadband photodetector applications
Photodetectors find their applications in several arenas such as that of bio-integrated electronics, health monitoring, high-definition imaging, remote controls, spectroscopy, and others. Therefore, photodetectors play an ... -
Two-dimensional materials based artificial synapses for neuromorphic applications
The need and demand for continuous high-speed, energy-efficient hardware advancement is undisputed. Traditional computing system with von Neumann architecture leads to high energy consumption and latency due to a huge ... -
Two-Dimensional Nanomaterials for Chemiresistive Gas Sensors: Towards Development of Breath based Diagnostics
Breath based Diagnostics (BbD) can enable a paradigm shift in the Point-of-Care Diagnostic (PoCD) devices. Exhaled human breath has been demonstrated to contain over 2000 volatile organic and inorganic compounds, some of ... -
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 ...
