Numerical Investigation Of A Reaction In A Batch Reactor: Flammability Limits, M. J Sexton, Harvinder Sidhu, Mark Nelson
Numerical Investigation Of A Reaction In A Batch Reactor: Flammability Limits, M. J Sexton, Harvinder Sidhu, Mark Nelson
Faculty of Engineering and Information Sciences - Papers: Part A
We study the spatial behaviour of the hydrogen-chlorine reaction in a batch reactor. The solutions exhibit regimes of slow and fast reaction. The main aim of this work is to distinguish between flaming and non-flaming mixtures from the numerical solutions. After setting out a practical criterion for flammability, we construct diagrams in parameter space which display the regions in which the reaction mixture is flammable.
Numerical Investigation Of The Angle Of Repose Of Monosized Spheres, Y C. Zhou, B H. Xu, Aibing Yu, Paul Zulli
Numerical Investigation Of The Angle Of Repose Of Monosized Spheres, Y C. Zhou, B H. Xu, Aibing Yu, Paul Zulli
Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents a numerical study of the angle of repose, a most important macroscopic parameter in characterizing granular materials, by means of a modified distinct element method. Emphasis is given to the effect of variables related to factors such as particle characteristics, material properties, and geometrical constraints. The results show that sliding and rolling frictions are the primary reasons for the formation of a sandpile; particle size and container thickness significantly influence the angle of repose; and the angle of repose is not so sensitive to density, Poisson's ratio, damping coefficient, and Young's modulus. Increasing rolling friction coefficient or …
A Three-Dimensional Numerical Model Of The Response Of The Australian North West Shelf To Tropical Cyclones, Song-Ping Zhu, Jorg Imberger
A Three-Dimensional Numerical Model Of The Response Of The Australian North West Shelf To Tropical Cyclones, Song-Ping Zhu, Jorg Imberger
Faculty of Engineering and Information Sciences - Papers: Part A
A three-dimensional barotropic and baroclinic model is developed to simulate currents and temperature changes induced by tropical cyclones traversing the continental shelf and slope region of the Australian North West Shelf. The model is based on a layered, explicit, finite difference formulation using the nonlinear primitive equations with an embedded entrainment scheme; a mixed-surface-layer interface is defined, which is allowed to shift from one interface to another, depending on the strength of a storm. The model has been tested by simulating the currents and temperature changes induced by tropical cyclones Orson and Ian. The modelled currents and temperatures agreed well …
