Zhang works with staff scientists Peter Driscoll and Cian Wilson to develop a suite of CFD code that integrates energy, mass, species, momentum, crystal motion, and phase change in a multicomponent system. It would apply to general magmatic systems like ore deposits, magma chambers, and Earth’s basal magma ocean.
They start from basic conservation laws and set up a group of partial differential equations, closed by an equation of state. This system will be discretized on Cartesian and spherical coordinates by the finite difference/finite volume/ finite element method.
They solve this system and focus on the following but not limited to: convection patterns, effects of crystal motion on chemical differentiation, component-rich melt motion and its impact on the heterogeneity of mantle, the time scale of cooling, relations to crust formation and topography.
