    Numerical simulation of the horizontal Bridgman growth. Part I: Two-dimensional flow (1987)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 7 (1987), S. 29-47 
    Details
    ISSN: 0271-2091
    Keywords: Finite Elements ; Transient Flows ; Three-dimensional Flows ; Natural Convection ; Interfaces Oscillatory Flows ; Crystal Growth ; Semiconductors ; Gallium Arsenide ; Engineering ; Engineering General
    Source: Wiley InterScience Backfile Collection 1832-2000

    Notes: We study the generation of periodic velocity and temperature fields in a plane horizontal crucible of molten metal under the action of a horizontal temperature gradient. The geometry and the boundary conditions are similar to those encountered in the Bridgman growth process of semiconductor crystals, although the present paper is limited to two-dimensional flows. We use transient finite difference and finite element algorithms which lead to identical results. We demonstrate the oscillatory mechanism in two different geometries.

    A comparison of mixed methods for solving the flow of a Maxwell fluid (1984)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 4 (1984), S. 1065-1081 
    Details
    ISSN: 0271-2091
    Keywords: Viscoelastic Fluids ; Polymer Flow ; Finite Elements ; Engineering ; Engineering General
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The proficiency of available mixed methods for solving the flow of a Maxwell fluid is evaluated through their application to the same problem. The reasons for the usual degeneracy of the numerical results beyond some level of elasticity are investigated. The best-performing technique is applied to the flow through an abrupt 4/1 contraction.
