Research

Dr Das's primary research interests span the broad area of emerging clean energy technologies with a particular focus on the thermo-fluid aspects of Li-ion batteries, fuel cells, flow batteries, and solar-fuel generators. He utilises a synergistic combination of advanced experimental characterisation and diagnostics together with multiphysics mathematical modelling and computer simulation for linking fundamental science to the design and development of better performing and robust energy devices and identify a direction for cost-effective materials for these systems.

The aim of Dr Das's current research is to tackle the technical obstacles to the recycling and re-use of vehicle battery packs and the widespread adoption of fuel cell vehicles. The challenges he is tackling include fast charging, thermal safety, recycling and reuse of vehicle battery packs, durability, cost, and water and thermal transport in fuel cells for vehicle and drone applications, and high-fidelity multiscale modelling of battery packs and fuel cell stacks. He's also interested in fundamental studies in the areas of nature-inspired thermal transport, convective heat transfer, and nanofluid. Visit the Sustainable Energy Systems group's (EnSys group) website and the ReLiB project site for more details.

Dr Das has given a number of invited talks and lectures at universities and presented at many international conferences on the topics of hydrogen fuel cells, convective heat transfer and microfluidics. He has served as a reviewer for leading journals, conference session chair, and symposium organiser. Dr Das has an excellent publishing record that includes 34 peer-reviewed journal articles and over 90 scientific publications. According to Google Scholar, the total number of Dr Das's citation is over 1500 and an associated h-index of 19.
