报告摘要:
A safe and secure future for humanity depends to
a large extent on the development of sustainable and economic energy resources,
and will require fundamental science and engineering contributions. In this
talk, I will present an overview ofsome of my work on the
advancement of energy systems in electronics, oil and gas, and solar energy
sectors.
Cooling of electronic systems, particularly high
performance data centers, is a highly energy intensive process. In 2013, data
centers consumed about 100 billion kWh of electricity in the U.S. alone and it
is expected that by 2020, the carbon footprint of data centers will exceed that
of the airline industry. One of the solutions to reduce energy consumption is to
move from conventional air cooling to liquid cooling, and in that respect I
will present a computer-aided molecular design approach for development of
novel heat transfer fluids for cooling of such systems. The fluids designed in
this work not only possess superior heat transfer properties, but also
significantly lower global warming potentials. I will also present a critical
evaluation of nanoparticle dispersions (or nanofluids) for heat transfer
applications and show, contrary to widely held belief, the effective thermal
conductivity of nanofluids decreases with decreasing particle size.
In conventional oil and gas industries,
clathrate hydrates of natural gases are associated with many energy
transportation (‘flow assurance’) related problems. However, gas hydrates also
present a potential future energy resource, as it is estimated that more than
1015 m3 of natural gas is present in oceanic and
permafrost gas hydrate deposits. I will present some of my work on hydrate
phase equilibria modeling, including the application of a quantum chemical
approach, COSMO, andflowloop studies carried out at the Exxon-Mobil flowloop
facility.
I will also present my work related tothe solar
industry, which has been growing at a tremendous pace for the last 10-15 years.
As the price of solar grade silicon has dropped from about $350/kg in 2008 to
about $19/kg in 2015, there is a considerable need to advance and optimize
process systems in the solar industry. I will present a few examples from manufacturing
of silicon for photovoltaic applications, and how a lack of thermophysical
property data on chlorosilanes and poor assumptions in process design affect
the productivity of silicon.
