A Systems approach for utility assessment of Energy resources in rural Applications
The main objective of the thesis is to develop a systems approach to assess the utilities of alternative energy resources in the context of rural India. The methodology proposed includes those energy resources also which ... -
Radiative interactions in boundary layers
The flow of a compressible, viscous, heat-conducting, radiating gray gas parallel to a gray semi-infinite flat plate is considered. The radiation field is described by using the differential approximation. N, the ratio of ... -
Development of Specialised Tribometer for Advanced Tribosystem Evaluation
This thesis presents a comprehensive study on the development and validation of force-controlled tribometers to accurately evaluate tribo-contacts under realistic test conditions. The research addresses the gap in conventional ... -
Passive Interfacial Evaporation-based Thermal Desalination Systems
Desalination offers a promising solution to the global water shortage by utilizing the vast resource of seawater. With 26% of the world’s population lacking access to potable water currently, there is a growing need to ... -
Electrohydrodynamics of a Viscoelastic Drop
The behavior of a drop in electric fields is critical for diverse natural and industrial applications, including inkjet printing and electrohydrodynamic atomization. This complex phenomenon is governed by the balance of ... -
Development of a Planar Robotic Platform with Localized Magnetic Actuation and its Applications for Untethered Ferromagnetic Robots and Shape-morphing Compliant Robots
This thesis focuses on the development of a solenoid-grid-based setup for independent planar actuation of multiple ferromagnetic robots referred to as ferrobots, by locally varying the magnetic field in different regions ... -
Fracture and indentation behavior of shape memory alloys
Shape memory alloys (SMAs) are metallic systems capable of recovering large strains, typically in the range of 7 to 10%. A clear understanding of the fracture behaviour of SMAs is crucial to prevent failures, especially ... -
Experimental study of sudden expansion in pipe flow
An Experimental Study of Sudden Expansion in Pipe Flow Flow through a sudden expansion, though the simplest and perhaps the earliest problem of fluid flow separation, still leaves much to be understood. The sudden expansion ... -
Development and application of a new method for detection of structural equivalence in graphs
This thesis mainly concerns the isomorphism problem encountered in computerized structural synthesis of kinematic chains. The contributions of the thesis to the study of structural aspects of linkages are the following. 1. ... -
Holographic interferometric study of natural convective heat transfer in vertical rectangular enclosures
Natural convective flows, induced by buoyancy forces on the fluid, in rectangular enclosures are important in many engineering applications such as thermal insulation of buildings, double-glazed windows and in flat plate ... -
Numerical studies of some non-linear problems in fluid mechanics
The problem of flow around a circular cylinder has long attracted the attention of many research workers because of its many practical applications and exciting mathematical features. This thesis contains the results of ... -
Two dimensional modelling of annular two phase flow
A two-dimensional model for analyzing annular two-phase flow through tubular geometry, based on the solution of continuity, momentum, and energy equations, is presented. The numerical approach employed is an adaptation of ... -
Geometric modeliing using slice representation
The thesis addresses mainly two issues in geometric modeling, high-level modeling techniques and reconstruction. High-level modeling techniques essentially include boolean operations on objects with same as well as different ... -
Experimental studies on travelling bubble cavitatin noise
An effectively controlled uniform travelling bubble cavitation was made possible at almost all freestream conditions by seeding the flow with artificial nuclei generated by electrolysis within the boundary layer of three ... -
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. ... -
Extended finite simulations of cohensive crack propagation under mode-3 loading
Modeling of propagating discontinuities (cracks) is a challenging problem in the field of computational mechanics. Numerical techniques such as Finite Difference Method (FDM), Boundary Element Method (BEM), and Finite ... -
Lossless collisions and complex behaviour in simple impacting systems
Humans have always tried to take cues from the animal kingdom, incorporating ideas into their creations, either w ith an intention o f devising a new one or making the existing ones better. Animal locomotion not only ... -
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 ... -
Thin film flows : integral methods and experiments on the circular hydraulic jump
This work is an integral analysis of radial and planar thin liquid film flows and an experimental study on the circular hydraulic jump on a circular horizontal plate. These thin film flows are obtained either by the ...
