Smart textiles with Tuneable Architectures for Multifunctional Applications
Innovations in electronics and the rapid developments in communication systems have been unprecedented and made life easier. One such advancement is wireless electronics, where gadgets operate in gigahertz frequencies – ... -
Coalescence of Polymeric Droplets
Coalescence is an energy minimization phenomenon in which two equilibrium droplets undergo a transition to attain a final equilibrium state, i.e., a coalesced state. Coalescence begins with a point contact between the ... -
Experimental and Numerical Studies on an Automobile Air Conditioning System with Refrigerants R134a, R1234yf and R1234ze(E)
The HydroFluoroCarbons (HFCs) synthesized as alternatives to ChloroFluoroCarbons (CFCs), though friendly to tratospheric ozone, have high Global Warming Potential (GWP). Despite this, numerous applications currently employ ... -
Gaze Estimation in the Wild - Models, Datasets and Usability
Human eye gaze estimation research has numerous applications in diverse fields from Human Computer Interaction (HCI) to aviation. Non-intrusive video oculography based methods are classified into two categories based on ... -
Sub-Newtonian Coalescence in Polymeric Fluids
Droplet coalescence is a thermodynamic equilibration process driven by surface energy minimization. The physics of this phenomenon is characterized by the temporal evolution of a liquid bridge formed upon the proximate ... -
Influence of surface topography on wear and debris morphology of polymers
The artificial knee and hip joints comprise a polymer-metal tribological system where soft polymers slide against hard metallic surfaces. When a polymer slides on it, the micro hard asperities remove the polymers in the ... -
Inclusive and Eye-Gaze Controlled Human-Robot Interaction for Persons with Severe Speech and Motor Impairment
Most individuals perform various activities of daily living without having to con sciously think and plan about them. People talk, cook their food, move around the house, drive to their workplace and schools, play sports, ... -
Gravity flow of granular materials through a vertical channel
Grains and powders are the second most widely used materials in industries and daily life after simple fluids. There are a variety of granular materials such as food grains, detergents, tablets and capsules, fertilizers, ... -
Analysis of Residual Estimate of Local Truncation Error
This thesis focuses on understanding the behaviour of the residual error estimator, referred to as R- parameter, in the context of Finite Volume Method. R-parameter measures the local truncation error (LTE) which is generated ... -
Parallel methods to solve large-scale stochastic linear and nonlinear mechanics problems in a domain decomposition framework
Parallel methods to solve large-scale stochastic linear and nonlinear mechanics problems in a domain decomposition framework Mechanics problems with inherent uncertainties are mathematically modeled using stochastic partial ... -
A multi-physics-based modelling approach to predict mechanical and thermo-mechanical behaviour of cementitious composite in a multi-scale framework
Concrete is a heterogeneous material whose constituents (e.g., cement paste, aggregate etc.) range from a characteristic length-scale dimension of a nanometre to a metre. Owing to the heterogeneity of concrete and the ... -
On the development of sensible heat storage for concentrated solar power applications: Thermo-fluid management and materials
Sensible heat storages have extensive use in thermal energy deployment, including concentrated solar power (CSP) applications. Usually, CSP pants demand various techno-economic features in sensible heat storage, such as ... -
Thermochemical conversion of biomass – single particle and packed bed: Experimental and Numerical Studies
The current work uses experimental and numerical techniques to analyze the thermochemical conversion of a single biomass particle exposed to various reactive environments – varying temperatures and O2, CO2 and H2O ... -
Space-Time Gauge Theories for Continuum Modelling of Viscoplasticity, Damage And Electro-Magneto-Mechanical Phenomena in Solids
Over the years, sustained research efforts have aimed to understand the material behaviour under a broad range of response regimes, especially from micromechanical or phenomenological perspectives — via both continuum ... -
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, ... -
Study of gas-fine flow in a packed bed with an application to the ironmaking blast furnace
The iron and steelmaking industry uses coal as the primary reducing agent. The carbon that is the major component of coal is finally released into the environment as carbon dioxide. One of the effective ways to reduce the ... -
Enhancement in corrosion resistance of selected high entropy alloys by incorporation of carbon nanotubes
High entropy alloys (HEAs) have attracted considerable interest due to their remarkable structural and functional properties. HEAs generally contain 5–13 principal elements with the concentrations of each component lying ... -
Small-amplitude Oscillations in Hypersonic Double-cone Flow
Unsteady compressible flows typically pose problems with rich dynamics. The broad concern of this thesis is the shock wave unsteadiness that arises in external high-speed flow over a double-cone body. This unsteadiness is ... -
Novel L12 precipitate hardened Co-base alloys
Conventional cobalt base superalloys relied on solid-solution and carbide precipitate based strengthening. They lacked high temperature (more than 800 ˚C) creep strength as compared to Ni-base superalloys which are ... -
Interfacial Engineering of Hierarchical Carbon Fiber Reinforced Epoxy Laminates for Mechanical Property Enhancement and Self-healing Ability
Carbon fiber-reinforced epoxy (CFRE) laminates have become a significant component in aircraft industries over the years due to their superior mechanical and highly tunable properties. However, the interfacial area between ...
