Looking for an opportunity to make an impact?
Leidos is seeking a Multiphase Computational Engineer to join our research support team at the US Department of Energy National Energy Technology Laboratory (NETL) in Morgantown, WV.
The successful candidate will support collaborative research for modeling of energy technologies that often encompass pyrolysis, combustion, and gasification. Current research initiatives involve carbon capture through polymeric reaction, hydrogen storage, and upgrading of biomass and municipal solid waste for potential use as fuel. Other research relates to high-performance coal-based and natural gas-based energy systems. Duties include the development and application of advanced modeling tools and techniques to design and optimize the performance of carbon and hydrogen capture techniques as well as advanced energy and related systems based on biomass, municipal solid waste, coal, natural gas, and other fuels.
Work performed is primarily directed toward mathematical and computational modeling, as well as software development, as it relates to advanced energy systems. This work will emphasize application of computational fluid dynamics (CFD) to novel multiphase flow reactors and devices including circulating fluidized beds, fixed beds, particle classifiers, catalytic reactors, and other advanced energy systems. In-house simulation will emphasize NETL’s MFiX modeling suite, which includes Two-Fluid (TFM), discrete element (DEM), coarse-grained discrete element (CG-DEM), and Particle-in-Cell (PIC) models. The incumbent will work closely with NETL multiphase flow computational scientists to assist them with detailed code applications, development, and validation studies. Work assignments will be in support of the NETL Computational Device Engineering Team and Multiphase Flow Science program in the Research & Innovation Center (CDE-RIC).
