Stability of wall-bounded compressible shear flows
In this work, the linear stability of compressible shear flows in channels and pipes are studied. A steady fully-developed laminar flow of an ideal gas, driven in a channel and a pipe by a constant body acceleration, is ... -
Stall Flutter of a Cascade of Blades at Low Reynolds Number
(2017-12-05)Due to the requirements for high blade loading, modern turbo‐machine blades operate very close to the stall regime. This can lead to flow separation with periodic shedding of vortices, which could lead to self induced ... -
Static Balancing of Rigid-Body Linkages and Compliant Mechanisms
(2018-03-07)Static balance is the reduction or elimination of the actuating effort in quasi-static motion of a mechanical system by adding non-dissipative force interactions to the system. In recent years, there is increasing recognition ... -
Statics of Shallow Bistable Arches
Bistable arches have two force-free stable equilibrium configurations. They also show multimodality by switching between their stable states in multiple deformation pathways. These two attributes and their nonlinear ... -
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ... -
Structural acoustics of perforated panels
In this work, radiation and transmission of sound through flexible perforated panels set in infinite rigid baffles are investigated. The treatment is largely analytical using Fourier transforms and contour integrations. ... -
Structure of the Tropical Easterly Jet in NCAR CAM-3.1 GCM
(2018-04-24)This thesis examines the structure of the Tropical Easterly Jet (TEJ) in a General Circulation Model (GCM). The TEJ is observed only during the Indian summer monsoon period and is strongest during July and August. The jet ... -
Studies for Design of Layered Ceramic Armour Inspired by Seashells
(2018-06-26)Pearly layers in seashells, also known as nacreous layers, are reported to be three orders of magnitude tougher than their primary constituent, aragonite. Their high toughness is attributed to a particular structure of ... -

Studies In The Dynamics Of Two And Three Wheeled Vehicles
(2016-09-09)Two and three-wheeled vehicles are being used in increasing numbers in many emerging countries. The dynamics of such vehicles are very different from those of cars and other means of transportation. This thesis deals with ... -
Studies On Automization And Sprays Of Plant Oil Biofuels Using Laser-Based Diagnostics
(2014-12-12)Atomization characteristics of liquid fuel sprays control combustion efficiency and emissions in engines. The present work is motivated by the need to study the atomization and spray structure of vegetable oil biofuels for ... -
Studies on Flow Dynamics and Spray Swirl Interactions in Gas Turbine Combustor
Coupling of spray with the coherent structures of a highly turbulent flow has been a long-standing problem especially in the context of liquid fuel delivery systems in gas turbine combustors. The atomizer in a gas turbine ... -
Studies on Friction Stir Welding of Aluminium AA2024 Alloy to Pure Copper
Aluminium-copper joints are widely used in electrical applications due to their unique properties. However, joining of these metals by conventional welding techniques is restricted due to the formation of brittle (bulk ... -
Studies On Friction Stir Welding Of Precipitation Hardenable Aluminium Alloys
(2010-06-10)Friction Stir Welding (FSW) is an emerging solid state welding process. It has been a proven method for welding high strength aluminium alloys which were previously not recommended for conventional fusion welding. Since ... -
Studies On Fuel-Air Stratification And Combustion Modelling In A CNG-Fuelled Engine
(2016-11-19)In-cylinder fuel-air mixing in a compressed natural gas (CNG)-fuelled, single-cylinder, spark-ignited engine is analysed using a transient three-dimensional computational fluid dynamic model built and run using STAR-CD, a ... -
Studies on Metal Hydride Based Multifunctional Coupled Thermal Battery Systems
Thermal energy storage systems (TESS) based on chemisorption/thermochemical reactions have several advantages over conventional thermal storage systems based on sensible and latent heat. The advantages include high energy ...
