Flow characteristics of sharp-edged orifices,quadrant-edged orifices and nozzles
This thesis presents an integrated study of flow past sharp-edged orifices, quadrant-edged orifices and long radius nozzles, covering different aspects such as metering characteristics, loss characteristics and flow ... -
Flow in pipes of uniform and non-uniform cross-sections with physiological applications
Laminar flow in pipes and channels with uniform and non-uniform cross-sections plays an important role in many engineering and physiological flow problems. Flow of blood through catheterised and stenosed (constricted) blood ... -
Flow Induced Instabilities, Shear-Thickening And Fluctuation Relations In Sheared Soft Matter
(2016-09-09)In day to day life we encounter many different materials which are intermediate between crystalline solids and simple liquids that include paints , glues , suspensions, polymers, surfactants, food and cosmetic products and ... -
Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ... -
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ... -
Fluctuations in quantum transport in topological insulators
Topological insulators (TIs) belong to a new class of materials characterized by linear surface states, which emerge in the bulk band gap due to non-trivial topology of the band structure. These surface states have various ... -
Fluid Flow And Electrochemical Bias Induced Effects In Carbon Nanotubes And Raman Studies On Iron Perovskites
(2011-09-30)This thesis is divided into two parts; the first part presents results on the effect of the flow of fluids and electrochemical bias on single walled carbon nanotubes (SWNT). Issues pertaining to the entry of water into the ... -
Fluid-Elastic Interactions in Flutter And Flapping Wing Propulsion
(2017-10-06)This study seeks to understand the interplay of vorticity and elasto-dynamics that forms the basis for a fluttering flag and flapping wing propulsion, and factors that distinguish one from the other. The fluid dynamics is ... -
Fluoranthene-Based Materials for Non-Doped Blue Organic Light-Emitting Diodes
(2018-05-16)The organic light-emitting diode (OLED) technology is emerging to be the future technology of choice for thin, flexible and efficient display and lighting panels and is a potential competitor for the existing flat panel ... -
Fluorescence of Manganese in mixed sulphate glasses and Crystalline medium.
The observed fluorescence decay of Mn²? in potassium sulphate–zinc sulphate glass is of single exponential at low (3 mole %) and high concentrations (12 mole %) of manganese. At higher concentrations of manganese, concentration ... -
