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. ...
Discrete particulate description of elastic structures undergoing geometrically nonlinear deformation and dynamic particle interaction
The mechanical behaviour of deformable bodies in a particulate environment has been an area of increasing interest across a wide spectrum of systems and scale. A composite ensemble of deformable structures and discrete ...
Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral
assembly components. Exact disassembly path determination of the components is essential because the ...
Modelling spatial and non-spatial conflicts across multiple design domains
This thesis aims to detect spatial and non-spatial conflicts in product design arising out of requirements in different design domains. Handling such conflicts requires modelling the non-geometric knowledge outside the ...
Posturing for Autonomous Digital Human Model
Digital Human Models (DHMs) are representations of humans in virtual environments that have applications in diverse disciplines. In the context of engineering design, DHMs are used to assess if a proposed design satisfies ...
Design and Development of Hybrid Metal and Polymer Additive Manufacturing System
Additive manufacturing (AM) is a layer-based manufacturing process aimed at producing parts directly from a Computer-aided design (CAD) model. There are various types of AM systems, which can be classified based on: (i) ...
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 ...
Topological Derivative-based Optimization of Fiber-reinforced Structures, Coupled Thermoelastic Structures, and Compliant Mechanisms
The topological derivative of a functional quantifies the sensitivity with respect to an infinitesimal domain perturbations such as a hole, an inclusion, a source term, a crack, etc. In this thesis, topological derivatives ...
