Job Description

The High-Performance Algorithms and Complex Fluids (HPACF) group in the Computational Science Center at NREL has an opening for a full-time postdoctoral researcher to support multiphase modeling projects pertaining to bioenergy conversion processes. The researcher will develop and apply state-of-the-art two-fluid/mixture computational fluid dynamics (CFD) models to simulate reacting multiphase flows in aerated bioreactors and immobilized enzyme-based reactors. This computational modeling work will involve extending three-dimensional modeling capabilities within existing software packages such as OpenFOAM and reduced dimensional models using Cantera or other reacting flow packages. The researcher will also provide actionable guidance to experimental/industry partners on reactor operation and optimization.

Primary Duties Include:

• Configuring and executing simulations, specifically of aerobic fermentation and/or enzymatic systems.
• Work with collaborators at NREL and other potential partners (national laboratories, universities and industry) to identify appropriate computational models and simulations to efficiently address client needs.
• Add capabilities to existing CFD modeling tools as necessary to achieve project objectives in a timely fashion, including development of kinetic or mechanistic reaction models for enzymatic conversion.
• Effectively communicate and collaborate with researchers and engineers operating relevant reactor systems to define the requirements of the simulations/models, obtain necessary data as input for the simulation, and provide meaningful interpretation of the results to guide experiments, operations, and engineering designs.
• Work with management and senior staff to plan and design projects, determine technical objectives, and interact with and provide regular project reports to government and/or industrial clients.
• Disseminate knowledge through publications in technical journals and presentations at conferences, symposia, and review meetings. Provide reports on technical work and input to technical publications and presentations.
