Research Interests

thermo-fluidics fundamentals (multi-phase flows, boiling-condensation, phase change materials; thermal management); micro/ nanotechnology (scanning probe lithography, nanosynthesis), nanofluids, MEMS (micro-electro-mechanical-systems), microfluidics, nanofluidics, confined fluids (shale-oil/ non-conventional reservoirs, hydraulic fracturing); energy-water nexus, thermal  energy  storage/ concentrated solar power, molten salt nanofluids; numerical simulations: network models/ lumped systems models, Finite Elements Analyses (FEA), Computational Fluids/ Heat Transfer (CFD/CHT), Molecular Dynamics  (MD).

 

ABSTRACT: We are developing nanotechnology-enabled platforms for enhancing cooling, sensing and energy storage (involving both experimental and computational studies). Coupling of thermal and hydro-dynamic features during phase change (boiling, condensation) causes spatio-temporal fluctuations of surface temperature at the micro/nanoscales, which are termed as “cold-spots” and can transmit over 60-90%  of  the  total  heat  transfer.  Using Carbon-Nanotube (CNT) nanocoatings - cooling was enhanced by 60~300% by leveraging cold-spots and the “nanofin” effect (enhanced surface area). Using silicon nanofins - cooling was enhanced by ~120%. Nanothermocouples and diodetemperature nano-sensors integrated with the nanocoatings enabled the study of chaos/ fractal structures in boiling.

Specific heat capacity was enhanced by ~120% using nanofluids. This has applications in the energy technologies, such as:  concentrated  solar  power/  CSP  (thermal  energy  storage/  TES),  nuclear, oil and gas exploration (deep drilling, reservoir engineering using nanotracers). Microchannel experiments using nanofluids showed that the precipitated nanoparticles behaved as nanofins (enhanced surface area) that dominate heat transfer for micro/nanoscale flows.

DPN™ (Dip Pen Nanolithography™) leverages Scanning Probe  Microscopy using microfluidics.  Commercial microfluidic  devices  called  “Inkwells™” were developed earlier. The next generation microfluidic devices are being developed for DPN (e.g., Fountain Pen Nanolithography, “centiwells”). The applications are in nanocatalysis, bio-nanotechnology, maskless-lithography and nanosensors for homeland security, bio-security and explosives detection (e.g., “nano-nose”/ “nano-tongue”). We invented a gasless process for synthesis of organic nanoparticles under ambient conditions and the synthesis temperature of CNT was reduced to less than 300 °C (patent awarded in 2013).

BIOGRAPHY:Dr. Banerjee received his Ph.D. in Mechanical Engineering from UCLA (with minor in MEMS). He received 3 M.S. degrees and was invited to 4 national honor societies. He attended the Indian Institute of Technology (IIT), Kharagpur for his Bachelor of Technology (Honors).
