The Multiphase CFD Research Scientist in this position will develop and apply advanced modeling tools and techniques to design and optimize the performance of advanced energy systems based on coal, natural gas, and other fuels and technologies. Work performed by this position is primarily directed toward mathematical and computational modeling of, and software development for, advanced energy systems, primarily based on fossil fuels. This work will emphasize the development and application of verification, and validation using the NETL MFiX Software Suite. The Multiphase CFD Research Scientist will also design and recommend the development of fundamental physical experiments to support and validate the VV&UQ activities. Work assignments will be in support of the NETL R&IC Multiphase Flow Science team. The Multiphase CFD Research Scientist will also provide mentoring support to junior researchers in mathematical modeling and software development. 

Primary Responsibilities Include:

  • Providing R&D technical support for the NETL multiphase flow sciences program and provide mentoring and guidance for junior researchers in mathematical modeling and software development.
  • Collaborating closely with the multiphase flow science program members on developing numerical /analytical / computational and mathematical studies of advanced energy conversion systems. Apply experimental data to model validation and improvement.
  • Performing computational model development and computational research for advanced energy conversion systems.
  • Developing high fidelity analytical and computational models of steady state and dynamic flows in advanced energy conversion systems.
  • Analyzing experimental data from laboratory tests and published data from other authors.
  • Presenting ideas and results to the research team.
  • Contributing to future research planning and assisting with proposals.  
  • Working independently and collaboratively with members of the research team to meet milestones and deliverables.
  • Assisting or leading efforts in writing research papers and creating conference presentations.

Required Qualifications:

  • Ph.D. in mechanical engineering, applied mathematics, aerospace engineering, nuclear engineering or a closely related field with an emphasis in computational multiphase fluid dynamics in gas-solids reacting flows, numerical analysis, and mathematical modeling.  1 – 2 years of postgraduate research and development experience in computational, mathematical and analytical model development relevant to energy conversion and chemical process systems that includes an emphasis on computational multiphase flow with experience in the development and application of verification, validation, and uncertainty quantification techniques to multiphase flows.
  • Ability to develop and use computational fluid dynamics models for multiphase unsteady flows which span multiple flow regimes.
  • Ability to design, implement, and maintain scientific software and run application in a supercomputing environment.
  • Experience in FORTRAN, C, Python, and C++ computer languages.
  • Ability to design and implement new computational models as well as the ability to assess and modify existing models in computational codes used by NETL researchers; ability to develop, design, and recommend physical experiments to obtain data necessary for model validation and uncertainty quantification.
  • Proficiency in computational modeling of complex multiphase flows, heat transfer, and thermal management.
  • Expertise in using CFD software such as the NETL MFiX Suite and ANSYS FLUENT/CFX, Star-CCM+, and OpenFOAM.
  • Experience in performing CFD simulation and comparing results of the analysis with experimental measurements.
  • Working knowledge of multiphase flow modeling and analysis techniques using different methodologies for gas-solid and gas-liquid multiphase flows.
  • Ability to document model development activities including, but not limited to, modeling theory, numerical techniques, verification and validation tests, and user manuals.

Preferred Qualifications:

Experience/knowledge is preferred in the following areas –

  • Expertise in applications of computational fluid dynamics, Discrete Element Method, especially using the NETL MFiX Software Suite to energy related applications.
