Atomization characteristics of alternative aviation biofuels, Jet A-1, and water from a hybrid airblast atomizer
Studies on the atomization of sustainable aviation fuels (SAF) from aircraft engine atomizers are essential to replace the present fossil type jet fuel to counter the rise in aviation-caused CO2 emissions in the atmosphere. ...
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 ...
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. ...
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 ...
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 ...
Advanced Optimal Spacecraft Guidance For Terminal Phase Rendezvous and Docking
There have been growing interest in Rendezvous and Docking (RVD) missions for on-orbit refueling, on-orbit servicing, orbital debris removal, etc. A very important requirement in RVD missions is soft-docking at the terminal ...
Resin flow in porous preform during VARTM: A theoretical and experimental investigation
In recent times, fiber reinforced polymer (FRP) composites have received enormous attention
due to their exhibited improved mechanical properties, lightweight and design
flexibility to manufacture large structures as an ...
Control of shock-induced vortex breakdown in Transonic regime on a slender delta wing body configuration using blowing
Modern high speed aircrafts feature highly swept and low aspect ratio wings, mainly to
increase the critical Mach number and reduce the wave drag. A special case of swept wings
is wings with triangular planform commonly ...
Electric Field-Guided Alignment of Carbon Nanotubes in Polymer Matrix Composites for Structural Applications
Carbon nanotubes (CNTs) have been extensively researched for diverse applications in recent years. In the present work, the use of low frequency non-uniform alternating electric fields to manipulate the alignment behavior ...
Spectral Analysis of Wave Motion in Nonlocal Continuum Theories of Elasticity
Traditionally, in solid mechanics, classical continuum theories of elasticity have been an important
tool in the examinations of behaviour of solids under external loads. However, due to
absence of length scale information ...
