Studies in gas-solid reactions
Non-catalytic gas-solid reactions are of great industrial importance and have therefore attracted considerable research effort. As a result, a number of models have been proposed in literature. Among the early models, the ... -
Polysterene-based compatibilizers for polymer blending : main chain epoxidation of high molecular weight polystyrene
Polystyrene has often been functionalized for its use in various commercial applications, but most often the reactive functional groups have been substituted on its benzene ring. In the present work, epoxy functional groups ... -
Bay of Bengal freshwater in the tropical Indian Ocean
The annual total continental runoff into the Bay of Bengal (BoB) is more than half the runoff into the entire tropical Indian Ocean. The net freshwater (FW) content in the Bay of Bengal mixed layer increases from a minimum ... -
Predictability of tropical coupled ocean-atmosphere model and its dependence on initial conditions
El Niño and Southern Oscillation (ENSO) is the dominant interannual signal in the tropics. This aperiodic phenomenon arises out of strong interactions between the tropical ocean and the atmosphere. Investigations with ... -
Andaman sea circulation in a high-resolution OGCM
The objective of this study is to understand the circulation of the Andaman Sea, which is unique by geography and oceanography, using a high-resolution Ocean General Circulation Model (ROMS) in tandem with altimeter and ... -
Investigation on the linkage between mystery of excess atmospheric absorption and state of mixing of aerosols
In order to understand the response of the Earth–atmosphere system to anthropogenic aerosol forcing, it’s essential to know the relative impact of the various aerosol species on the radiation budget. Most of the models ... -
Advanced Thermomechanical Modeling of Soft Matter Systems
This thesis deals with advanced thermomechanical modeling of complex soft matter systems, including polymers, gels, and biological tissues. It addresses a few fundamental limitations of classical theories, such as the ... -
An Information Visualization Support for Practitioner-Like Interpretation OF Life Cycle Assessment Results
Life Cycle Assessment (LCA) is widely used to quantify the environmental impacts of products and systems, yet its effective application in design practice remains limited due to challenges in interpreting complex, ... -
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 ... -
Interplay of Performance and Robustness in Architected and Naturally Evolved Structures
Humans have long drawn inspiration from nature, drawing on its intricate and efficient designs for solving complex engineering challenges. One such feature is the aperiodicity observed in biological systems, which exhibit ... -
Experimental investigations into tensile properties of large specimens and sensitivity of notch size on the fracture and fatigue behavior of concrete
Full text embargo upto Jan 15, 2027 Concrete, which is the second largest material used after water, is a highly heterogeneous quasi-brittle material containing ingredients at different length scales. The fracture and ... -
Analytical and numerical solutions of some moving boundary problems. vol. 2
This thesis presents analytical and numerical solutions of some Moving Boundary Problems (MBP’s), especially those pertaining to solidification/melting. Since solidification problems are mathematically analogous to melting ... -
Propagation of a curved weak shock front
Waves are ubiquitous in the physical world. The study of general laws that govern their propagation is, therefore, important. In particular, nonlinear hyperbolic waves are frequently encountered, for some of which the ... -
On hardy-sobolev inequality and its application to certain singular problems
Inequalities involving integrals of a function and its derivatives appear frequently in various branches of mathematics and represent a useful tool, e.g., in the theory and practice of differential equations, in the theory ... -
Strain controlled low cycle fatigue and creep-fatigue interaction behaviour of a type 316L(N) stainless steel
Type 316L(N) stainless steel (SS) is the currently favored structural material for several high-temperature components in the primary side of the liquid metal-cooled fast breeder reactor. The choice of this material is ... -
Analytical and numerical solutions of some moving boundary problems. vol.1
Title of the Thesis: Analytical and Numerical Solutions of Some Moving Boundary Problems This thesis presents analytical and numerical solutions of some Moving Boundary Problems (MBP’s), especially those pertaining to ... -
Structure and rheology of lyotropic liquid crystalline suspensions
Suspensions in the form of solid–liquid dispersions are encountered in several industrial applications. Household detergents and processed foods can be modeled as a suspension of phase-separated or externally added particulate ... -
Heterogeneous catalytic oxidation of isobutylene in vapour-phase Ph.D. Thesis
Kinetics of the catalytic vapour-phase oxidation of isobutylene to methacrolein, an important raw material for polymer industries, was investigated in a fixed-bed isothermal flow reactor. Out of a number of catalysts ...
