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 ... -
Studies in the oxidation of benzene
Oxidation as an important unit process having considerable promise has been highlighted. A new process of phenol manufacture based on the direct oxidation of benzene as opposed to the multi-stage processes (like Scientific ... -
Vapour phase catalytic hydrogenation of aniline
A very large effort has been directed towards heterogeneous catalysis and establishing the proper form for equations that express the rate of surface reactions as a function of system variables. These equations range ... -
Dehydrogenation of cyclohenxanol to cyclohexanone
The dehydrogenation of cyclohexanol to cyclohexanone has been studied in detail. The thermodynamic equilibrium constants at various temperatures have been collected from literature and the equilibrium conversions have been ...
