We are glad to introduce our SFB 1313 guest Dr. Andreas Yiotis from the National Centre of Scientific Research (NCSR) Demokritos who will stay at the Institute of Applied Mechanics (CE) of the University of Stuttgart from 22nd to 25th January 2019. Andreas Yiotis is beeing our guest within SFB 1313's project area B and C.
About Andreas Yiotis
Andreas Yiotis is an Associate Researcher at the Environmental Research Laboratory of the National Center for Scientific Research (NCSR) “Demokritos”, Athens, Greece. He holds a Diploma (1997) and a PhD (2003) both in Chemical Engineering from the National Technical University of Athens.
His work focuses primarily on the theoretical and numerical modeling of transport processes in porous media, such as soils, fractured rocks, fibrous materials and membranes, across several spatiotemporal scales. He is particularly interested in how pore scale phenomena, rigorously modeled by means of pore network and Lattice Boltzmann methods, eventually determine the macroscopic (field) scale behaviour of multiphase flows within geologic formations in applications related to Conventional and Enhanced Oil Recovery, Soil Remediation and geologic CO2 sequestration.
Research interests
His research focuses on transport phenomena in porous media with emphasis in soils, rocks and membranes. Through the theoretical study of physical mechanisms emanating at the pore scale, he develops computationally efficient numerical modeling tools for a variety of processes typically encountered in a series of technological and scientific applications. These include evaporative drying from fractured petroleum reservoirs, multiphase flows related to Oil Recovery processes (drainage, imbibition, blob dynamics), hydrodynamic dispersion, flow of gases through fibrous media and metal hydrides, thermodynamics and heat transfer dynamics in coupled Fuel Cell/Metal Hydride systems, including design optimization. Besides his modeling work, he also designs and performs rigorous experimental studies of multiphase flow processes in model and micro-engineered porous media aiming at obtaining better insight on the effect of pore scale mechanisms at the macroscopic/field scale behaviour of such systems.
During his stay, he will give a SFB 1313 lecture, entitled: "Effective steady-state flow regimes during the stranding and mobilization of NAPL ganglia within stochastically reconstructed porous domains".
