The Simulator Mechanics

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The objective of this research was to determine the role of neural feedback and muscle mechanics in the generation of physiological tremor oscillation. This research developed a neuromuscular model to simulate the individual and resulting oscillatory mechanisms of tremor. The oscillations found in EMG signal were also analysed empirically from EMG data from 54 subjects using Hilbert Transform and rectification to obtain the envelope of the signal. The time between rhythmical waveform patterns in the EMG signal, TC was found to be 78ms.

Research and improve scheduling admission control mechanism to enhance QoS based on incoming burst rate prediction at core node to improve scheduling efficiency for low QoS bursts but still ensure a level of service quality for high QoS bursts. The effectiveness of the scheduling admission control mechanism was valued through simulation and mathematical analysis.

When boron carbide is used as a neutron absorber in nuclear power plants, large quantities of helium are produced. To simulate the gas behaviour, helium implantations were carried out in boron carbide. The samples were then annealed up to 1500 °C in order to observe the influence of temperature and duration of annealing.

The final goal of the work is to provide useful recommendations and guidelines for the design of a cold plug for the emergency draining system of a molten salt reactor. Some numerical thermal simulations were performed with ANSYS mechanical (Finite Element Method) to be compared with results of the experiments and to make extrapolations for a new component to be used in a reactor.

This thesis aims to develop finite element models for studying vibration of the 2D-FGM beam. These models require high reliability, good convergence speed and be able to evaluate the influence of material parameters, geometric parameters as well as being able to simulate the effect of shear deformation on vibration characteristics and dynamic responses of the 2D-FGM beam.

Construction of bounds on the elastic moduli of isotropic multicomponent materials which involve three-point correlation parameters. We use numerical methods to study several representative material models. Construction of three-point correlation bounds on the effective elastic shear modulus of composite materials and applications of the bounds are given to some composites.
