Graduate Seminar: Chris MacMinn, Yale University
4:00 pm - 5:00 pm
Location: CPE 2.208
Faculty candidate Dr. Christopher MacMinn, Postdoctoral Associate at Yale University, will give a talk entitled "Coupling across scales in geophysical flows" as part of the Claude R. Hocott Graduate Seminar Series.
Abstract: Small-scale physical mechanisms often have an important, complex, and in most cases poorly understood impact on geophysical and environmental fluid flows at much larger scales. This coupling across scales plays a particularly strong role in porous rocks, soils, and sediments, where small-scale physical mechanisms such as capillarity, erosion, and reaction can play a key role in large-scale phenomena.
Here, I will present two striking examples of this coupling in the context of (1) carbon sequestration, where storage security relies on the action of millimeter-scale trapping mechanisms to immobilize kilometer-scale plumes of buoyant carbon dioxide in the subsurface, and (2) fluid injection into soft granular solids, where macroscopic poroelastic behavior is the result of complex grain-scale mechanics.
