    The Asian Corpus of English (ACE)

    No full text
    As a lingua franca, English plays an extremely important role in Asia: there are more speakers of English in Asia than the total number of native English speakers. To study English as a lingua franca (ELF) in Asia, it is important to establish a large-scale representative spoken Asian ELF corpus. Inspired by the Vienna–Oxford International Corpus of English (VOICE), the first large-scale corpus of spoken ELF interactions in Europe, a project team in Asia led by Professor Andy Kirkpatrick compiled the Asian Corpus of English (ACE), a million-word corpus of spoken ELF interactions in Asia (https://corpus.eduhk.hk/ace). This chapter will introduce the overall design of the ACE corpus, the data collection methods, and the functionalities of the ACE online system. Some examples of ACE-based research will also be shown. This chapter aims to help those who wish to conduct research using the Asian Corpus of English.No Full Tex

    Effects of swirl on intermittency characteristics in turbulent non-premixed flames

    No full text
    Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with turbulence and combustion modelling based on the localised dynamic Smagorinsky and the steady laminar flamelet models respectively. Probability density function (pdf) distributions demonstrate a Gaussian shape closer to the centreline region of the flame and a delta function at the far radial position. However, non-Gaussian pdfs are observed for velocity and mixture fraction on the centreline in a region where centre jet precession occurs. Non-Gaussian behaviour is also observed for the temperature pdfs close to the centreline region of the flame. Due to the occurrence of recirculation zones, the variation from turbulent to non turbulent flow is more rapid for the velocity than the mixture fraction and therefore indicates how rapidly turbulence affects the molecular transport in these regions of the flame

    Determining the effectiveness of the HERS-SA Academy using the Kirkpatrick framework of training evaluation

    No full text
    Includes bibliographical references (leaves 76-86).The research evaluated the outcomes of Higher Education Resource Service South Africa (HERS-SA) Academy using the Kirkpatrick (1996a) framework of training evaluation. The study used a three-stage research design to evaluate Academy outcomes in tenns of the reactions, learning and behaviour levels of the Kirkpatrick (1996a) framework. Two main findings emerged from the research: (1) the reactions and learning outcomes of the Academy are successful while the behaviour outcomes are only partially successful, and (2) increased confidence and increased understanding of HE are by far the strongest outcomes of the Academy. Based on the major findings of the research, a number of recommendations were made primarily to improve the behaviour outcomes of the Academy

    Investigation of the influence of swirl on a confined coannular swirl jet

    No full text
    Large Eddy Simulations are used to model a turbulent confined coannular combustor and examine the effects of swirl on the flow field and mixing. Three separate simulations with relatively high mesh resolutions and different swirl numbers have been carried out using a finite volume method on a Cartesian non-uniform structured grid. A localised dynamic Smagorinsky model is used to parameterize the subgrid scale turbulence. The snapshots of the axial and swirl velocities and velocity vector fields show the complex flow patterns developing with increased swirl number and the rapid decay of axial momentum. Precessing vortex cores (PVC) were identified for all three cases and the mean axial velocity plots indicate that the upstream extremity of the vortex breakdown bubble shifts towards the inlet as the swirl number increases. The calculated power spectra indicate the distinct precession frequency for high swirl number. Probability density functions of axial velocity showed the changes of their distributions from approximately Gaussian to non-Gaussian with increased swirl number. The swirl has a large effect on the rate of decay of the axial velocity throughout the domain, whereas only has a significant effect on the decay of swirl velocity in the near field close to the jet inlet. The relation between swirl number and the axial extent of the recirculation zone is approximately linear. Radial plots of mean passive scalar and its variance also demonstrate an increase in the rate of mixing with increasing swirl number

    Large Eddy Simulation of a turbulent swirling coaxial jet

    No full text
    This work uses the Large Eddy Simulation (LES) technique to study velocity and passive scalar mixing along with intermittency of a spatially evolving turbulent coaxial swirl jet. The simulations captured the potential core and also predicted high level turbulence intensities in the inner mixing regions. The Probability Density Functions (PDFs) and radial intermittency plots revealed an intermittent mixing behaviour especially in the outer region of the flow where the fluctuations of velocity rapidly change from rotational to irrotational and vice versa. The PDF and radial intermittency profiles exhibit Gaussian and non- Gaussian distributions close to the jet centreline and away from the centreline, respectively

    A study of mixing and intermittency in a coaxial turbulent jet

    No full text
    A large eddy simulation study of mixing and intermittency of a coaxial turbulent jet discharging into an unconfined domain has been conducted. The work aims to gain insight into the mixing and intermittency of turbulent coaxial jet configurations. The coaxial jet considered has relatively high jet velocities for both core and annular jets with an aspect ratio (core jet to annular jet) of 1.48. The computations resolved the temporal development of large-scale flow structures by solving the transport equations for the spatially filtered mass, momentum and passive scalar on a non-uniform Cartesian grid and employed the localized dynamic Smagorinsky eddy viscosity as a sub-grid scale turbulence model. The results for the time-averaged mean velocities, associated turbulence fluctuations and mean passive scalar fields are presented. The initial inner and outer potential cores and the shear layers established between two cores have been resolved, together with the establishment of high turbulence regions between the shear layers. The passive scalar fields developing from the core and the bypass flow were found to exhibit differences at near and far field locations. Probability density distributions of instantaneous mixture fraction and velocity have been created from which intermittency has been calculated and the development of intermittency from the probability density distributions for instantaneous velocity follows similar variations as for the passive scalar fields
