Course Abstract:
The increasing demand for accurate and efficient simulation of multiphase flow, heat transfer and mechanics in subsurface formations motivates development of advanced computational methods. The non-linear, heterogeneous, uncertain, dynamic and coupled nature of the mathematical formulations make such developments challenging, yet possible if a multiscale methodology is properly devised for each system type. Such multiscale methodologies allow for a physics-based algebraic dynamic multilevel description of the highly-resolved heterogeneous discrete equations in both space and time. At the same time, they allow for crossing up and down between resolutions, with systematic error reduction to any desired norm. This short course is offered to enable the attendees to get an in-depth knowledge and hands-on implementation skills for “Coupled Flow-Heat-Mechanics systems”, “Fractured Media”, and “multiscale modeling and simulation for them”. At the end of the course, all participants will develop their own multiscale simulator in Matlab/Python from scratch; contribute to more comprehensive codes and get some hands-on experience on physics behind heterogeneity, fractures, deformation, multiphase flow and low-high-enthalpy heat transfer.
