Title:
Micro and Nano-scale Transport Processes: Applications in Porous Media
Abstract:
A number of engineering applications, like oil
recovery and fuel cells, involves the transport of fluid (liquid and gases)
through narrow confinements, often in the order of μm and nm dimensions. In order to understand the transport through
such complex porous media, it is important to first characterize the
pore-geometry. Dr. Mitra’s research group has pioneered the use of Focused Ion
Beam – Scanning Electron Microscopy (FIB-SEM) to understand the porous geometry
of natural reservoir rock. Based on such understanding, the research group has
developed a novel microfluidics device – “Reservoir-on-a-Chip (ROC)”, which
allows to perform oil recovery studies in a miniaturized platform. In case of
gas flow, the research group has developed a new mass transport model to
characterize the diffusion processes within the gas diffusion layer (GDL) of a
fuel cell electrode. Also, mass transport experiments are conducted to validate
multi-component diffusion models.
Short Bio:
Sushanta Mitra received his PhD in Mechanical

the University of Alberta, Canada. He is the Director of Micro and Nano-scale
Transport Lab (www.mece.ualberta.ca/mntl) and the Team Leader for
Nano-Bio-Energy Network (www.mece.ualberta.ca/nben). He has published more than
145 papers in peer-reviewed journals and conference proceedings. He is also the
Editor of Microfluidics and Nanofluidics Handbook. For his contribution in the
field of mechanical engineering, he has been elected the fellow of the American
Society of Mechanical Engineers (ASME) and the Canadian Society of Mechanical
Engineers (CSME).
