Postdoctoral Fellow; PREP

PREP Research Associate

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas.

Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Title:

Characterization for rechargeable battery fires

U.S. Citizen Preferred

This work will involve conducting research at different scales to characterize the generation of fires from rechargeable batteries. The researcher will conduct large- and bench-scale fire experiments using characterization technologies, including heat flux gauges, radiometers, thermal imaging cameras, and thermocouples. The goal of these experiments is to determine appropriate methods to characterize the ignition, heat transfer, and heat release rate of rechargeable batteries.

In doing so, this work will advance the metrology needed to assess the hazard presented by rechargeable battery fires.

• Conducting experiments to assess the evolution of thermal runaway in a rechargeable battery and the resulting fire.
• Determining methods to collect, process, and analyze data generated from heat flux gauges, radiometers, thermal imaging cameras, and thermocouples.
• Assessing the uncertainty of measurements collected from experiments.
• Using modeling tools to simulate the heat transfer of a rechargeable battery as it transitions to thermal runaway.
• Presenting results at internal meetings and meetings with external stakeholders.
• Ensuring that results, protocols, software, and documentation have been archived and disseminated in archival journals.

• A doctoral degree in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, or Fire Protection Engineering, or a closely related field, must be obtained by the start of the appointment, or a degree confirmation letter must state completion of requirements to receive the degree.
• Expert experience in convective and radiative heat transfer; heat release rate measurements using a cone calorimeter; and dynamics of fires generated from battery energy storage systems or electric vehicles.
• Familiarity with the use of computational fluid dynamics models (Fire Dynamics Simulator or FireFOAM).
• Demonstrated knowledge of data acquisition systems using National Instruments equipment.
• Common scripting languages (Python, Matlab).
• Ability to develop research plans and document research results in journals.
• Strong oral and written communication skills.
