Draw on experience with Computational Fluid Dynamics (CFD), Discrete Element Method (DEM), ANSYS FLUENT, and Fortran and C/C++ programming language to provide R&D technical support for scientific research associated with Dept of Energy National Energy Technology Laboratory; conduct mathematical modeling of advanced energy systems and actively participate in software development; collaborate closely with multiphase flow science program members and create numerical /analytical /computational and mathematical studies of advanced energy conversion systems; apply experimental data to model validation and improvement; develop high fidelity analytical and computational models of steady state and dynamic flows in advanced energy conversion systems; analyze experimental data from laboratory tests and published data from other authors; contribute to future research planning and assist with proposals; work independently and collaboratively with members of the research team to meet milestones and deliverables; assist or lead efforts in writing research papers and creating conference presentations. This work will emphasize application of computational fluid dynamics (CFD) to novel multiphase flow reactors and devices including circulating fluid beds, particle classifiers and other advanced energy systems.
