  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.
