Supercomputer Simulation of Multiscale Dynamic Behaviour in Multiphase Deformable Porous Media. This project will establish and consolidate links between leading groups in China and Australia to develop a new and unique multiscale computational model and algorithm for simulating multiphase nonlinear behaviours of the porous media under dynamic loading conditions, and improve technology transfer between the two groups by the mobility of the ARC International Fellow. This will aid Australian geosc ....Supercomputer Simulation of Multiscale Dynamic Behaviour in Multiphase Deformable Porous Media. This project will establish and consolidate links between leading groups in China and Australia to develop a new and unique multiscale computational model and algorithm for simulating multiphase nonlinear behaviours of the porous media under dynamic loading conditions, and improve technology transfer between the two groups by the mobility of the ARC International Fellow. This will aid Australian geoscience and mining industry, such as in HFR geothermal/UCG energy facility design, construction, risk assessment and production and could help Australia shift away from greenhouse gases and become a world leader in the emerging worldwide HFR geothermal/UCG industry.Read moreRead less
Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduct ....Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduction and upward transport of melt. Ocean trench migration (?rollback? subduction) is of special interest because it gives patterns of temperature and vertical motion most conducive to melting. Results will be used to interpret geochemical and seismic data from the Tonga subduction zone in the South Pacific.Read moreRead less
