Experimental Investigations on Ramp-induced Large Separation Bubble in a Hypersonic Flow
Shockwave Boundary Layer Interactions (SBLIs) are ubiquitous in supersonic/ hypersonic flows and often lead to the separation of the boundary layer. These separations can be broadly classified into small and large ... -
Hybrid Physics-Data Driven Models for the Solution of Mechanics Based Inverse Problems
Inverse problems pose a significant challenge as they aim to estimate the causal factors that result in a measured response. However, the responses are often truncated, partially available, and corrupted by measurement ... -
Analysis of Residual Estimate of Local Truncation Error
This thesis focuses on understanding the behaviour of the residual error estimator, referred to as R- parameter, in the context of Finite Volume Method. R-parameter measures the local truncation error (LTE) which is generated ... -
Small-amplitude Oscillations in Hypersonic Double-cone Flow
Unsteady compressible flows typically pose problems with rich dynamics. The broad concern of this thesis is the shock wave unsteadiness that arises in external high-speed flow over a double-cone body. This unsteadiness is ... -
Structure of Turbulent, Swirling Round Jets
The present study deals with the numerical analysis of the effect of the swirl in the self-preservation region of the turbulent round jet. However, a large number of literature exists for the analysis of near-exit regions—very ... -
Control and Safety of Multi-UAV Systems for Collaborative Payload Transportation and Target Tracking
Unmanned aerial vehicles (UAVs) have been widely used in reconnaissance, remote sensing, disaster relief, and agricultural applications. Many applications require multiple UAVs to cooperate to complete the assigned tasks. ... -
Resource Allocation for Natural Disasters using a Game-theoretic Framework
The occurrence of a severe natural disaster causes loss of life and destruction of properties. The overall criticality of the disaster depends on the nature of the disaster and the physical characteristics of the affected ... -
Microscale mechanical behaviour of ceramic matrix composites considering processing e ects
The current work explores the phenomenon of microscale damage mechanism driven quasi- ductile behaviour of C/BN/SiC ceramic matrix composite (CMC) at the microscale focusing on process-microstructure-property correlations. ... -
Drilling Damage in Laminated Polymer Matrix Composites Considering Thermal Efefcts: Experimental and Numerical Analysis
In the present work, drilling induced damage in multi-directional carbon fiber reinforced polymer (MD-CFRP) laminates has been investigated by experimental and numerical approaches. Exit-ply delamination during drilling ... -
Implicit Gradient Reconstruction for Unstructured Mesh Finite Volume Method
In the present work, an Implicit Gradient Reconstruction (IGR) method is proposed in the context of Finite Volume Methodology (FVM). There are three computationally intensive steps involved in a typical finite volume ... -
Numerical Study of Accelerating Turbulent Boundary Layers
This thesis focuses on the prediction of favourable pressure gradient turbulent boundary layer flows. Particularly, the focus is on mild favourable pressure gradient turbulent boundary layers and relaminarising turbulent ... -
Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ... -
On late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both in engineering applications and natural phenomena. A laminar-turbulent transition process is inherent to its development involving ... -
An Experimental Investigation of Transitional and Turbulent Channel Flow
This thesis is a comprehensive experimental investigation of transitional and turbulent channel flow in the Reynolds number range of Reτ = 55 − 1559. Towards this objective, a new channel flow facility was designed and ... -
Automated methods of natural resource mapping with Remote Sensing Big data in Hadoop MapReduce framework
For several decades, remote sensing (RS) tools have provided platforms for the large-scale exploration of natural resources across the planetary bodies of our solar system. In the context of Indian remote sensing, mineral ... -
Design, Control and Experimental Validation of a Robust Adaptive Feedback Linearization Controller for a Quadcopter Manipulator System
A quadcopter manipulator system (QMS) is an aerial robot comprising a quadcopter with a three degree of freedom manipulator mounted at the bottom of the vehicle. An aerial robot can reach otherwise inaccessible ... -
Design and Performance Investigation of Supersonic Air-Intakes
Supersonic air-intake is an essential component of a ramjet engine. Typically, a ramjet powered missile that operate over a range of Mach numbers and maneuverability conditions uses a fixed geometry intake to ensure ... -
Direct Methods for Optimal Ascent Guidance
An ascent guidance algorithm determines the thrust vector that allows the spacecraft to reach the desired orbit. Generally, optimal ascent guidance algorithms try to reach the orbit while minimizing mission time or fuel. ... -
From Particles to People: Vicsek-Inspired Behavioural Modelling Frameworks
In this thesis, we develop different modelling frameworks to capture the processes of opinion formation and disease spread. The common theme binding them is a nearest-neighbour-based interaction rule; while the closeness ... -
Molecular simulation of thermal conductivity in DNA and phonon dispersion in layered materials
Heat conduction plays a key role and is linked to the underneath lattice structure. The heat transfer in soft matter materials like DNA and polymers is seldom understood and is deeply linked to the geometry and functional ...
