Employment

Multiple Post-Doctoral Research Positions and Educational Research support positions are available with the Multiphase Flow Science Team in the NETL in-house research program. These opportunities will be available through the Oak Ridge Institute for Science and Education (ORISE) program at the NETL Morgantown, WV location.

Post-Doctoral Research Opportunities

PD1: Multiphase CFD Modeling – Code Development and Applications

Positions will involve development, verification, validation, and application of Computational Fluid Dynamic (CFD) models in chemically reacting, multiphase flows using primarily the NETL MFiX code. For development work the ideal candidate will hold a PhD degree in computer science, mathematics, or engineering and have experience in CFD, DEM, and/or molecular dynamics (MD) code development. Programming expertise in C++, Fortran, C, or another programming language is required. Experience with parallel computing, including MPI and OpenMP is required. Familiarity with MFiX and multiphase flow is highly desired but not mandatory. Specific tasks include code profiling, algorithm development and implementation, writing reports/papers and making presentations to report the results of the research. The development team is geographically disperse making excellent communication skills a must. The primary area of CFD application is in energy conversion processes including coal and biomass gasification, chemical looping combustion, pyrolysis and gasification of solid feedstocks, solids classification, and carbon capture using solid sorbents or solvents. Applications to other technologies including chemical process, materials processing, etc. Experience with high performance computing platforms and CFD software packages such as the NETL MFiX Suite, ANSYS FLUENT, CPFD-Barracuda, or OpenFOAM is required. A Ph.D. degree in mechanical or chemical engineering or a closely related discipline is required. Please contact jobs@mfix.netl.doe.gov with any questions.

PD2: Multiphase Flow Laboratory Research

These positions involve the development and application of novel measurement and control techniques for multiphase flow systems, including granular and liquid slurry flows. The positions will involve experimental measurement of the flow field and agglomeration phenomenon in small scale fluidized beds. The ability to extract data from multiple experimental techniques is highly desired. These techniques might include Particle Image Velocimetry, Laser Doppler Velocimetry, sensor probes and high-speed pressure transducers. The data collected from these measurements will be used for development and validation of CFD models (e.g. MFiX, FLUENT) with emphasis on agglomeration model validation. The successful candidate will work in close collaboration with CFD modelers. Hence, prior experience in performing measurements in dense particulate flows and the ability to extract model specific information will be highly valued. Prior experience in statistical analysis of large quantities of data and physical interpretation of measured parameters is also desired. A Ph.D. degree in mechanical or chemical engineering or a closely related discipline is required. Please contact jobs@mfix.netl.doe.gov with any questions.

Educational Research Support Opportunities

UG1/G1: CFD Code Development

Acceleration and Development of computational fluid dynamics computer codes. The MFS team is expanding its expertise in scientific code acceleration. Responsibilities would include performance testing, scaling analysis, algorithm development, code refactoring, etc. There is opportunity to help in guiding and planning of future development activities. An undergraduate or graduate degree in Engineering, Computer Science or related field is required. Experience in C, FORTRAN, and programming techniques for CPU/GPU architectures is desired. Please contact jobs@mfix.netl.doe.gov with any questions.

UG2/G2: User Experience Development

Development, enhancement, optimization, and verification of graphical user interface (GUI) for interaction and control of computational fluid dynamics software. Design and implementation of pre-processing and post-processing tools and enhancement of MFS products. An undergraduate or graduate degree in Engineering, Computer Science or related field is required. The GUI will guide users in setting up simulations as well as controlling and guiding large multi-core simulations. Additionally, GUI usage will target workflow management, design optimization, and in situ statistical analysis of simulation results. An undergraduate or graduate degree in Engineering, Computer Science, or related field with experience in Python development (including leading scientific packages like Numpy, Scipy, and Sympy) is required. Experience with the Qt library and FORTRAN is desired. Please contact jobs@mfix.netl.doe.gov with any questions.

NETL, part of the U.S. Department of Energy (DOE) national laboratory system, is owned and operated by the DOE. NETL supports the DOE mission to advance the energy security of the United States. NETL implements a broad spectrum of energy and environmental research and development programs that will return benefits for generations to come. The MFS Team at NETL is a leader in the design of numerical modeling of gas-solids flows and simulations of devices of interest to DOE. The job location is at Morgantown, West Virginia research campus of NETL.

The Ph.D. must have been completed and granted by the university before starting the appointment. Applicants cannot have received the most recent degree more than five years prior to the date of application. Applicants must be U.S. Citizens or approved Foreign Nationals.

Opportunities exist for excellent performers to advance to full-time employment with the federal government, NETL contractors, and NETL University collaborators. These full-time employment opportunities will depend on job openings, citizenship status, and are filled by competitive employment solicitations.
