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 electrothermal energy storage, battery manufacturing and green steelmaking. The researcher will develop and apply multiphase/phase-field models to simulate solid/liquid phase transitions and yield stress fluids with and without chemical reactions. Applications may include structural deformations due to surrounding or penetrating fluids. The implementation of these models will involve original development of performance portable scientific software development and/or extensions of existing modeling software.

Primary Duties Include:

• Add capabilities to existing scientific software tools as necessary to achieve project objectives, including development of models for phase transitions that incorporate molecular-level physics. 
• Work with collaborators at NREL and other potential partners (national laboratories, universities, and industry) to identify appropriate computational models and/or model extensions, and design and execute simulation and analysis campaigns to efficiently address client needs.
• 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.

.

Basic Qualifications

Must be a recent PhD graduate within the last three years.

* Must meet educational requirements prior to employment start date.

Additional Required Qualifications

The successful candidate will be expected to make high impact contributions of direct relevance to phase transitioning flows that leverage her/his expertise and demonstrated accomplishments in the following areas:

• Strong grasp of numerical methods in CFD and ability to implement and extend them in original or existing C++ and Python-based codes.
• Knowledge of multiphase continuum models for solid-liquid systems with phase-change.

• Ability to leverage high-performance computing resources for large-scale simulations.
• Use of Python for analysis and orchestration of workflows.
• Performing simulations studies that inform and collaborate with experimental projects.
• Ability to work independently and in teams and to deliver high-quality results within aggressive timelines.
• Track record of troubleshooting and problem-solving complex systems.

Preferred Qualifications

• Familiarity with open-source C++/Python libraries used in CFD, e.g. OpenFOAM, AMReX, MFEM, PyFR
• Experience in computational structural mechanics using finite-element or material-point methods.
• Strong publication record
• Excellent technical writing, interpersonal, and communication skills
