    Appl Math: Neil Ribe on "Thin-Shell Dynamics of Geophysical Subduction"

    McCormick-Engineering Sciences and Applied Mathematics (ESAM)

    11:15 AM M416, Technological Institute

    EVENT DETAILS

    Title: Thin-Shell Dynamics of Geophysical Subduction

    Speaker: Neil Ribe, Université Paris-Saclay

    Abstract: Subduction on Earth is the process whereby the planet’s stiff and dense outer shell (the lithosphere) sinks into the mantle below while deforming in complex ways over periods of millions of years. Because the typical Reynolds number of subduction-related flow is 10^(-20). understanding the process requires
    the theory of low Reynolds number hydrodynamics. Using a variety of idealized models of subduction in both Cartesian and spherical geometries, we obtain numerical flow solutions using the boundary-element method and interpret
    these using the theory of thin viscous shells. Aspects to be emphasized
    in this talk include the key lengthscales and dimensionless numbers that
    control subduction; the physical factors that determine which of several
    modes or styles of subduction is selected under given conditions; the
    complex state of stress in doubly-curved subducted shells; and the
    potential role of buckling instabilities during subduction.

    Bio: Neil M. Ribe received his PhD in Geophysical Sciences from the University
    of Chicago in 1981. After postdoctoral work at Columbia Unversity, he
    joined the faculty of the Department of Geology and Geophysics at Yale
    University. In 2000 he moved to France to take up a position with the
    CNRS, first at the Paris Geophysical Institute (IPGP) and then (since 2009)
    at the FAST laboratory in Orsay. He is a specialist in low Reynolds number
    hydrodynamics, applied both to the dynamics of the Earth’s interior and
    to a variety of problems in fundamental fluid mechanics and soft matter
    physics.
