Draw on experience with MFiX, Ansys Fluent, Fortran, Gambit, NX, and SpaceClaim to conduct analytical, experimental, investigative and other fact-finding work using standard scientific approaches and techniques to support principal scientific researchers with a concentration on modeling and analysis of complex gas-solids phenomena in reacting flows in novel combustion systems for reducing carbon emissions; observe, calculate, record and interpret the results of tests and analyses, and designs, constructs, modifies, calibrates, operates and maintains equipment used for these purposes or devised as a result of the work; develop computational fluid dynamics tools and models for advanced energy production and storage systems and apply experimental data for model validation and improvement; plan and execute laboratory research, maintaining substantial knowledge of state-of-the-art principles and theories, and contributing to scientific literature and conferences; develop solutions to complex technical issues. Specific duties will include utilizing our multiphase flow computational fluid dynamics (CFD) tools to model and study the co-pyrolysis and co-gasification of mixed feedstocks and develop novel gasification-based reactor designs to support the Office of Fossil Energy and Carbon Management’s strategic goals of maximizing hydrogen production and minimizing carbon dioxide emissions. Duties will also include developing CFD models for the design and analysis of novel direct air capture systems and characterizing the effect of reactor geometry, sorbent shape, and operating conditions on the reactor performance to serve as platforms for system optimization and process intensification. Additional duties include developing laboratory and bench-scale experiments in-house and collaborating with our partners to generate data to assist in CFD model development and validation.
