Research Groups & Projects

Select below for a brief description of each Group or Project.

Performs research and provides critically-evaluated data and models on a variety of fluid-based separation processes, including distillation, adsorption, and supercritical fluid extraction.

Collects and evaluates thermophysical data (more than 100 properties) of organic compounds.
Develops large thermophysical property databases and database-management systems.
Develops a concept and process of "dynamic compilation" of thermophysical property data to provide automatic critical data evaluation.
Develops software tools for global data collection, storage, exchange, and dissemination via the TRC Data Entry Facility.
Develops software protocols for the TRC Data Quality Assurance program.

The NIST Real Fuels Project grew out of a combustion community workshop that identified the databases and technical improvements required to translate our underlying scientific understanding of combustion to technological development.
The next generation of efficient engines will be developed by using accurate computer simulations. These simulation codes will combine accurate chemical kinetic models of combustion with computational fluid dynamics. Such simulation codes require the development of standards and tools for sharing, evaluating, and processing chemical kinetic models.
