Thermal Science and Engineering Division

Research Overview

●  GOALS

The objective of this division is to enable the most effective use of materials in carbon-neutral energy technologies and to improve the energy efficiency of thermal processes by expanding our knowledge of material thermophysical properties and thermal science and engineering. More specifically, research in the division aims at: expanding our knowledge-base of thermophysical properties of hydrogen and alternative refrigerants to enable their most efficient uses to reduce CO2 emissions; improving our understanding of the basic science of heat and mass transfer to enable the development of more efficient energy systems; and researching new thermal energy heat pump and refrigeration systems focused on the use of waste heat and new refrigerants for improved overall energy efficiency and reduced CO2 emissions.

 

●  DIVISION ROADMAP

 

●  RESEARCH HIGHLIGHTS

The PVT property, viscosity and thermal conductivity of hydrogen up to 100MPa and 500C has been measured. In addition, a compact curved wire vibrating method for viscosity measurement has been developed.  We have succeeded in measuring the thermal conductivity of multi-walled carbon nanotube(CNT) and in the in- and out-of –shell thermal conductivities. Pump-probe optical technique has been applied to generating and detection GHz frequency surface acoustic waves. Innovative T-type method was used to detect thermoelectric properties of CNT.

 

●  FUTURE DIRECTIONS

The Thermophysical Properties division will change its name to “Thermal Science and Engineering Division.” This new name represents more accurately the research thematic areas of the division.  Guided by the Division’s roadmap, the Division’s research in the future will focus on issues of: i) surface wettability in boiling and evaporation, ii) fundamental issues in nanoscale thermal transport; iii) low greenhouse potential refrigerants; iii) thermophysical property measurement by time-domain thermoreflectance; iv) low grade heat utilization systems; v) phase boundaries in fluid mixtures in the presence of hydrogen; vi) measurements of the viscosity, thermal conductivity and thermal diffusivity of carbon dioxide and its mixtures, vii) measuring in real-time of elastic constants of structural metals exposed to hydrogen using non-contact pump-probe optical methods, viii) efficient pump power use for hydrogen production (similar to chlorella algae).
