1st DARSim Seminar on Porous Media Flow Modeling & Simulation within the Faculty of Civil Engineering and Geosciences of TU Delft
14:40 – 14:45: Welcome and introduction Hadi Hajibeygi*, Mark Bakker, Timo Heimovara
14:45 – 15:05: Modeling of biogeochemical reactions in large-scale systems André van Turnhout* , Timo Heimovaara
15:10 – 15:30: Optimal use of subsurface space with Aquifer thermal energy storage Smart Grid Martin Bloemendal*, Vahab Rostampour, Marc Jaxa-Rosen
15:35 – 15:55: Modeling multi-path leakage of geosequestered CO2 Mehdi Musivand Arzanfudi*, Rafid Al Khouri
16:00 – 16:20: Dynamics of polymer rheology through different pore-shapes in microfluidic channels
Durgesh Kawale*, P. Boukany, Michiel Kreutzer, William Rossen, Pacelli Zitha
16:25 – 16:30: Conclusion remarks
Various high-quality research activities on modeling and simulation of porous media flow for different applications are being conducted in our Faculty. Many of them are multi-disciplinary in nature, and thus benefit from a more communicative and supportive environment among researchers with different expertise and interests. These series of seminars are developed to further facilitate such an environment by enhancing communication and broadening the knowledge of individual researchers of our Faculty, in the exciting field of porous media flow modeling and simulation. As to start, taking the chance of Darcy Lecture by Prof. Rainer Helmig on the same day (12:00, Room E), this event is planned. All researchers and students in our Faculty are highly motivated to attend (and volunteer to give a talk in future events) so that it only becomes a good start, but definitely not an end.
25 September 2015 – Lecture Room E – 14:40-16:30 (Darcy Lecture by Prof. Rainer Helmig is on the same day, 12:00-13:45, Room E)
