About the Role
Join our dynamic team at Inertia as a Computational Fluid Dynamics (CFD) Scientist, where you will spearhead the development and application of cutting-edge CFD simulations. Your expertise will be pivotal in understanding and predicting gas flow dynamics within our innovative fusion, target, and laser systems—elements vital to the performance, longevity, and operational efficiency of our projects.
This role emphasizes the creation and execution of high-fidelity CFD models in challenging environments characterized by extreme transience, turbulence, and radiation. Collaborating closely with physicists, simulation experts, and design engineers, you will convert intricate flow phenomena into practical engineering insights for our next-generation fusion power plant.
Key Responsibilities
Develop, execute, and analyze CFD simulations of fluid dynamics under a diverse array of operating conditions.
Model and refine transient and pulsed flow phenomena, optimizing thermal and mechanical performances and related systems.
Investigate the effects of chamber gas dynamics on various fusion-related systems, including:
Final optics performance and durability
Thermal management in high-power and pulsed systems
Target injection trajectories, stability, and survivability
Debris transport and chamber clearance
Chamber geometry, gas response, and surface interactions
Establish CFD workflows utilizing industry-standard software and research codes, encompassing mesh generation, boundary condition setup, solver configuration, and post-processing pipelines.
Integrate CFD outcomes with other physics models (such as radiation transport, thermomechanics, particle transport, and optical ray tracing) in partnership with the broader simulation team.
Conduct large-scale simulations and enhance scalable, effective computational workflows.
Validate CFD models against experimental data, analytical estimates, and cross-code validations wherever applicable.
Present findings clearly through reports, visualizations, and design reviews to facilitate engineering decision-making.
Required Qualifications
PhD or Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
