DC-Link Capacitor used in power converters as an energy buffer is one of the key components of aircraft Power and Thermal Management Controller (PTMC). Several factors in order to reduce the cost of the PTMC have been identified including the integration of the DC-link capacitor…

Phase change in solidification and melting can be described with the aid of discontinuous functions. The aim of this project is to establish effective methodologies for the solution of discontinuous phase-change problems. The classic capacitance method, which distributes the eff…
The goal of this research is to investigate the combined effects of glass fibre reinforcement and molecular orientation in polypropylene-short glass fibre composites. Specimens have been fabricated using the injection moulding process and drawn using a small die drawing rig. The…
The main objective of this project is to develop a "black-box" multigrid preconditioner for the iterative solution of finite element discretisations of the convection-diffusion equation with dominant convection. This equation can be considered a stand alone scalar problem or as …
In this thesis our primary interest is in developing adaptive solution methods for parabolic and elliptic partial differential equations. The convection-diffusion equation is used as a representative test problem. Investigations are made into adaptive temporal solvers implementi…
An effective approach to determine optimum welding process parameters is implementation of advanced computer aided engineering (CAE) tool that integrates efficient optimization techniques and numerical welding simulation. In this thesis, an automated computational methodology to…
Viscoelasticity has been used to model the deformation and stress displayed by many types of solids including biological materials, polymers and metals. Viscoelastic materials exhibit a memory effect, where the stress at the current time depends on the previous history of the st…
