Solar spectral diffuse radiance for a specified atmosphere
In many applications such as the design and performance evaluation of solar energy devices, remote sensing studies, meteorological and climatological studies, it is necessary to know the values of solar radiation reaching ... -
Some approximate methods of analysis of Non-Linear Dynamical systems
The present investigation concerns some approximate methods of analysis in the area of non-linear oscillations. The analysis includes the steady-state as well as the transient response of non-linear systems. In both cases, ... -
Sound Radiation from Rectangular Panels with Rectangular Cut-out/s
This is largely an analytical investigation and the objective of this study is to compute sound power radiated from rectangular panels that are placed in an infinite baffle (or a rigid wall) and that have rectangular ... -
Spatio-temporal Dynamics in Droplet Combustion Under Diverse Flow Conditions
Spray combustion of liquid fuels is one of the most ubiquitous modes of combustion used in a wide range of applications ranging from IC engines for transportation to Gas turbines in propulsion systems, owing to the high ... -
Specification and Verification of Tolerances for Parts with Free-Form Surfaces
(2017-11-27)The need for increased product variety and improved aesthetics require the manufacturing enterprise to reduce time to market and to increase use of free-form surfaces in the form of the product. These changes lead to ... -
Spherical Indentation Response of Bulk and Thin Film Shape Memory Alloys
Shape memory alloys (SMAs) have the ability to recover large strains upon undergoing a thermomechanical cycle. In addition to being used as structural elements, they can be patterned as thin films which can be employed in ... -
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ... -
Stability of unbounded and bounded granular shear flows
Recent computer simulations of granular flows (Hopkins & Louge 1991; Goldhirsch, Kui & Zanetti 1993) have identified an interesting picture of cluster formation. In this thesis, we have attempted to explain particle ... -
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 ... -
Stochhastic chatter theory
The machining process on modern machine tools is a dynamic phenomenon having cause-and-effect interaction under stochastic environments. With a steady increase in utilization parameters, intensive vibrations occur, which ... -
Stress analysis of spinning discs and shells
This thesis is concerned with the stress analysis of isotropic and orthotropic spinning discs and shells. The shell geometries considered in this thesis are: spherical shallow shell, conical shell, and cylindrical shell. ... -
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 ...
