A Study on the Influence of Reduced Electric Field on Plasma Assisted Combustion Kinetics
Plasma assisted combustion (PAC) technology has attracted much attention in the recent years as an innovative technique to improve the combustion efficiency. Plasma can enhance the combustion process mainly through two ... -
Valorization of Residual Ligno-celluloses from Anaerobic Digesters Through Product Recovery
Complete digestion of lignocellulosic biomass during anaerobic digestion (AD) is impossible due to recalcitrance created by lignin, consequently leaving behind a significant part of the feedstock unconverted to methane. ... -
State and Parameter Estimation in Water Distribution Systems
Water Distribution Systems (WDS) are one of the most important infrastructures in a society, which has a direct impact on human lives. Water authorities around the world are expected to supply the required amount of water ... -
Studies on Non-Destructive Evaluation of Friction Stir Weld Discontinuities with Probability of Detection
Friction stir welding(FSW) is a solid-state metal joining process which is currently being considered for joining of aerospace components. The zones associated with FSW are distinctly different from the fusion weld and ... -
Improved laboratory and computational models for thermal core–mantle interaction
The Earth's magnetic field is generated by thermochemical convection within its fluid outer core. The near-stationary high-latitude magnetic flux concentrations in the present day field indicate that convective ... -
Architecting Conjugated Molecules for Band Gap Engineering & Photostability
Organic photovoltaic (OPV) modules are flexible, light weight, transparent and thin compared to other emerging photovoltaic technologies, making them well-suited for applications ranging from solar windows to fabrics. A ... -
Electromagnetic interference shielding materials derived from epoxy based nanocomposites
The thesis entitled “EMI shielding materials derived from epoxy based nanocomposites” systematically studies the effect of CF and surface modified CF on the EMI shielding of epoxy composites. In addition, to target the ... -
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over the past few decades, researchers have studied physical models mimicking the tail beat of fishes in an effort to extract key physical ... -
Numerical Studies on Plastic Deformation, Notch Sensitivity and Fracture Behavior of Bulk Metallic Glasses and Composites
Bulk metallic glasses (BMGs) exhibit attractive properties such as high strength and resilience. However, they display negligible tensile ductility due to catastrophic crack propagation inside a dominant shear band (SB). ... -
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this emergence has been ... -
Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied for decades with only minor improvements. Boundary layer transition to turbulence in highMach number flow is one such topic, which, ... -
Experimental Investigations Into Fracture and Fatigue Behavior Of Plain and Reinforced Concrete Beams Using Acoustic Emission Technique
Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing ... -
Phononic bandgap engineering in cellular periodic structures and mechanical metamaterials
A methodology has been developed for the computation of phononic band structure of cellular periodic structures, structures with spatially repetitive patterns, using Frequency domain Spectral Finite Element Method along ... -
Liquid Jet in Swirling Cross Flow
Liquid jets in cross flows (JICF) have been an important part of spray research in the last few decades owing to the wide spectrum of applications ranging from agricultural sprays to aircraft gas turbine engines. However, ... -
An Evaluation of the Mechanical Behavior of some new High Temperature Materials
Two new high-temperature alloy systems have been discovered recently at the Indian Institute of Science, which form the basis of this thesis. The first alloy system is an Intermetallic-Intermetallic eutectic composite ... -
Development of an efficient domain decomposition algorithm for solving large stochastic mechanics problems
With the growth of computational resources available, demand on the accuracy and speed of simulation is steeply increasing. Accordingly, accounting for the variabilities in the simulations plays a pivotal role in taking ... -
On the analysis of axially loaded Euler-Bernoulli beam using Galerkin, Fourier transform, and Lie symmetry approach
The beam with axial load is one of the fundamental models in the field of physics and engineering. The applications of this model span from a guitar string to the rotating blade of a helicopter. It has an important role ... -
A Geochemical and Sr, Ca, Mg, Li isotopic study of the Godavari River draining the Deccan basalts
Chemical weathering of continental silicate rocks releases cations and anions which are eventually precipitated as carbonates on the ocean floor. This entire process transfers carbon from the atmosphere to the oceans leading ... -
Development of a coarsening resistant microstructure in precipitation strengthened aluminium alloys with Zr, Ta and Hf
The work herein aims at developing precipitation-strengthened aluminium-copper (Al-Cu) alloys that can meet the current challenges of the aeronautical and automobile sectors to increase the fuel efficiency where operating ...
