  • Numerical simulation of pressing wood-fiber composites

    Creator:
    Haselein, Clovis R.
    Abstract:
    A model to simulate the dry-process pressing of wood composites is presented. The model uses as its starting point a pre-existing mass and heat transfer model. A number of furnish material properties, including fluid permeability, thermal conductivity, hygroscopicity and rheological parameters, are reviewed and modified for use in the pressing...

  • Use of pore-scale network to model three-phase flow in a bedded unsaturated zone

    Creator:
    Zhang, Wenqian
    Abstract:
    Contamination of ground water by non-aqueous phase liquids (NAPLs) has received increasing attention. The most common approach to numerical modeling of NAPL movement through the unsaturated zone is the use of the finite difference or finite element methods to solve a set of partial differential equations derived from Darcy's law...

  • Two-dimensional temperature model for target materials bombarded by ion beams

    Creator:
    Bostick, Kent C.
    Abstract:
    The ion implantation process is a very precise, controllable, and reproducible method used to enhance material properties of finished components such as ball bearings. Essentially, the target material is bombarded by accelerated ions to form a thin alloyed layer in the substrate. As the ions deposit their kinetic energy in...

  • Predicting the thermo-mechanical behavior of a gypsum-to-wood nailed connection

    Creator:
    Fuller, James J.
    Abstract:
    With high costs of testing and rating a structural system for fire resistance, the utilization of computer simulations that approximate the integrity of structural subsystems could conceivably reduce development costs. Before an analysis of a light-frame wood system can occur, information on the components of the substructure must be known....
