Blast Mitigation Strategies for Marine Sandwich Structures
Blast mitigation is being researched from the time of world war II. There were full field blast tests and analytical studies on the performance of monolithic structures to mitigate blast load. Sandwich structures were also ... -
Bubble and conical forms of vortex breakdown in swirling jets
The present study focusses on vortex breakdown (VB), which occurs in axially convected swirling flows and is characterized by the development of an internal stagnation point and regions of reverse flow. VB 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 Investigation of Fuel Drop Impact on Unheated and Heated Solid
The modelling of spray-wall interaction encountered in engine combustors relies heavily on studies of single drop impact on heated solid surfaces. In the present thesis, the impact of a single fuel drop on a hot, smooth ... -
Flame Particle Tracking Analysis of Turbulence-Premixed Flame Interaction
This work describes the computational and theoretical developments made in the understanding of turbulence-premixed flame interaction, using both lean and rich H2-air mixtures, in a flow field of near-isotropic turbulence. ... -
A Generalised Modelling of Piezoelectric Composite Shells and Plates using Variational Asymptotic Method
In several fields of engineering, researchers are actively pursuing the possibility to use smart materials such as piezoelectric composites in order to make the structure smart. Piezoelectric materials have the capability ... -
Response of Granular Materials Towards Blast Loading
Granular media, such as sand, soil, and rocks, are commonly encountered in various engineering and geotechnical applications, and their response to blast loading is of significant interest. In this master’s thesis, the ... -
Robust Station-keeping and High-Precision Attitude Control for a Spacecraft on Sun–Earth L1 Halo Orbit
The halo orbits around the Sun-Earth L1 Lagrange point form an ideal location for deploying a solar observation spacecraft as they offer uninterrupted, long-duration visibility of the Sun. However, the complex orbital and ... -
Rotational Temperature Measurement in Hypersonic Shock Tunnel using Tunable Diode Laser Absorption Spectroscopy
Atmospheric entry of a spacecraft is considered as one of the critical phases in any planetary mission. Although it lasts only for a few minutes, rapid heating and deceleration can cause severe problems to the spacecraft. ... -
Satellite Attitude Determination from Terrestrial/Planetary Landmarks
Attitude Determination (AD) or specifying orientation relative to a known reference frame plays a crucial role in meeting the mission specific pointing goals of a satellite. Attitude sensors provide measurements of known ... -
Stress-Assisted Pitting Corrosion Studies in Metallic Structures Using Advanced Modeling Methodologies
Pitting corrosion poses a significant threat to deepwater oil and gas production facilities, yet our current understanding of its impact on specific systems such as steel catenary riser (SCR), tensioned leg platforms (TLP), ... -
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 ... -
Turbulence-Premixed Flame Interactions
The interaction between premixed flames and turbulence is an inherently non-linear phenomenon. Understanding such interactions has profound practical implications towards the development of better combustion devices and ...
