    Abstract

    The dynamic behavior of magmatic hydrothermal systems
    entails coupled and nonlinear multiphase flow, heat
    and solute transport, and deformation in highly heterogeneous
    media. Thus, quantitative analysis of these systems
    depends mainly on numerical solution of coupled partial differential
    equations and complementary equations of state
    (EOS). The past 2 decades have seen steady growth of computational
    power and the development of numerical models
    that have eliminated or minimized the need for various simplifying
    assumptions. Considerable heuristic insight has
    been gained from process-oriented numerical modeling.
    Recent modeling efforts employing relatively complete
    EOS and accurate transport calculations have revealed
    dynamic behavior that was damped by linearized, less accurate
    models, including fluid property control of hydrothermal
    plume temperatures and three-dimensional geometries.
    Other recent modeling results have further elucidated the
    controlling role of permeability structure and revealed the
    potential for significant hydrothermally driven deformation.
    Key areas for future research include incorporation of
    accurate EOS for the complete H2O-NaCl-CO2 system,
    more realistic treatment of material heterogeneity in space
    and time, realistic description of large-scale relative permeability
    behavior, and intercode benchmarking comparisons.
