    A finite element-spherical harmonics model for radiative transfer in inhomogeneous clouds. Part II. Some applications

    , Joint Assembly of the EGS/AGU/EUG, Pages: 223-237

    EVENT has been used to examine the effects of 3D cloud structure, distribution, and inhomogeneity on the scattering of visible solar radiation and the resulting 3D radiation field. Large eddy simulation and aircraft measurements are used to create realistic cloud fields which are continuous or broken with smooth or uneven tops. The values, patterns and variance in the resulting downwelling and upwelling radiation from incident visible solar radiation at different angles are then examined and compared to measurements. The results from EVENT confirm that 3D cloud structure is important in determining the visible radiation field, and that these results are strongly influenced by the solar zenith angle. The results match those from other models using visible solar radiation, and are supported by aircraft measurements of visible radiation, providing confidence in the new model. (C) 2004 Elsevier B.V.

    Numerical simulation of particle motion in dense phase pneumatic conveying

    , Pages: 167-172, ISSN: 1434-5021

    A gas-solids two-dimensional mathematical model was developed for plug flow of cohesionless particles in a horizontal pipeline in dense phase pneumatic conveying. The model was developed based on the discrete element method (DEM). For the gas phase, the Navier-Stokes equations were integrated by the semi-implicit method for pressure-linked equations (SIMPLE) scheme of Patankar employing the staggered grid system. For the particle motion the Newtonian equations of motion of individual particles were integrated, where repulsive and damping forces for particle collision, the gravity force, and the drag force were taken into account. For particle contact, a nonlinear spring and dash pot model for both normal and tangential components was used. In order to get more realistic results, the model uses realistic pneumatic system and material values.

    Overcoming Barriers to Restructuring in a Modular Visualization Environment

    , New York, NY, USA, 7th workshop on Workshop on languages, compilers, and run-time support for scalable systems, Publisher: ACM, Pages: 1-7

    This paper explores the potential for automatic cross-component optimisation in the Python / VTK-based MayaVi modular visualisation environment. The idea is to delay execution of the VTK components called from the MayaVi tool, which requires no significant structural change to the MayaVi code base, but which opens up the possibility for dynamic performance optimisations such as tiling, fusion, memoisation and shared-memory parallelisation. The paper concludes with experimental results on an unstructured mesh hierarchy model from an adaptive three-dimensional gravity current simulation.
