Prof. Vittorio Di Federico was invited to the Southern University of Science and Technology (SUSTech) in Shenzhen, China, to give the “Nanshan Distinguished Lecture on Environment” on “Complexity in Geologic Media flow across Scales” at the School of Environmental Science and Engineering on April 25th, 2019.

Prof. Vittorio Di Federico was invited to the Southern University of Science and Technology (SUSTech) in

Shenzhen, China, to give the  “Nanshan Distinguished Lecture on Environment” at the College of Engineering on April 25th, 2019. The invitation came from the Dean of the School of Environmental Science and Engineering at SUSTech, Prof. You-Kuan Zhang. SUSTech (http://www.sustc.edu.cn) is a Chinese University based in Shenzhen, China, one of the fastest-growing cities in the world and established in 1980 as China's first special economic zone. In his speech, titled “Complexity in Geologic Media flow across Scales”, Vittorio Di Federico presented

the challenges in modeling flow in geologic (natural) media. Additional challenges rise from the fact that these porous and fractured formations are characterized by heterogeneity on multiple scales, and that in subsurface flow, fluid rheology is often non-Newtonian. These fluids exhibit a nonlinear relationship between stress and strain, entailing nonlinear equations at all scales. In turn, the interaction between complex rheology and spatial heterogeneity produces additional complexity, and implies a need for a combination of theoretical, numerical and experimental approaches to identify synergetic effects. In his talk, he introduced non-Newtonian fluids and their relevance to subsurface flow, and presented a variety of applications dealing with flow in porous and fractured media at different scales.

Also presented in the talk was an introduction to Bologna University and its Department of Civil, Chemical, Environmental and Materials Engineering (DICAM), and the international degrees taught in English we offer.
