The Multiphase Flow Modeling Scientist in this position will support collaborative research in modeling of bioenergy technologies including biomass pyrolysis, combustion, gasification, and upgrading of biomass products for potential use as fuel. Activities will also include coal-based and natural gas-based energy systems that involves both NETL and LRST research team members. Duties include the development and application of advanced modeling tools and techniques to design and optimize the performance of advanced energy systems based on biomass, coal, natural gas, and other fuels and technologies.

Work performed by this position is primarily directed toward mathematical and computational modeling and software development for advanced energy systems, primarily based on biomass fuels. This work will emphasize application of the NETL MFiX Software Suite to novel multiphase flow reactors and devices including circulating fluid beds, particle classifiers, catalytic reactors and other advanced energy systems. Modeling will emphasize the Two-Fluid and Lagrangian methods including discrete element method (DEM), coarse-grained discrete element (CG-DEM) approach and Particle-in-Cell (PIC) approach. The Multiphase Flow Modeling Scientist will work closely with NETL multiphase flow modelers to assist them with detailed code application and validation. Work assignments will be in support of the NETL Computational Device Engineering Team and Multiphase Flow Science program in the RIC (CDE-RIC). The Multiphase Flow Modeling 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 chemical engineering, mechanical engineering, or a closely related field with an emphasis in computational multiphase fluid dynamics research involving reacting multiphase fluid dynamics in gas-solids, gas-liquids, liquid-solids, three-phase reacting flows, numerical analysis, and mathematical modeling; and less than 2 years prior relevant experience.


Preferred Qualifications:
  • 1-3 years of postgraduate research and development experience in computational, mathematical and analytical model development relevant to fossil and biomass energy conversion and chemical process systems that includes an emphasis on computational multiphase flow with experience in development and application of Lagrangian and Two-Fluid Modeling approaches. Familiarity with upgrading of biomass pyrolysis gas through catalytic processes and computational modeling of these systems are desired.
  • Ability to develop and apply complex multiphase computational fluid dynamics codes to study multiphase systems, including fluid beds and other configurations important to energy conversion and chemical reactors. Experience in using the NETL MFiX Software Suite to study these multiphase flow systems is required.
  • Experience in scientific code development and application with an emphasis on creating computational models to aid in the design, understanding and analysis of complex multiphase flow systems, including Discrete Element Methods, Two-Fluid Modeling, and Kinetic Theory of Granular Flow approaches.
  • Familiarity with upgrading of biomass pyrolysis gas through catalytic processes and computational modeling of these systems are desired. Knowledge of bioreactor systems including simulation of reactor performance is desired.
  • Experience in CFD modeling of chemical process reactors such as polymerization reactors is desired.
  • Experience with CFD software including FLUENT, OpenFOAM, MFiX, and COMSOL and Parallel Programming with C/C++, Fortran, Large-scale simulations on High Performance Computing facilities. Experience in mesh generation (GAMBIT, ICEM-CFD), data collection and analysis (Tecplot, Paraview).
