About the job
Focused Energy is an innovative fusion energy startup aiming to produce limitless clean energy to responsibly address the future global demand. By harnessing and commercializing laser-induced inertial fusion—a clean and highly efficient power generation technology—we are on the verge of ensuring a secure and scalable future energy supply.
We are in search of a highly proficient and enthusiastic Computational Fluid Dynamics (CFD) Engineer to be a vital part of our Science and Engineering team. In this essential, hands-on technical role, you will be responsible for the development and integration of sophisticated CFD models pertaining to the fusion chamber environment. Your contributions will directly influence the design of core reactor systems, ensuring component durability and optimizing critical processes within the chamber. You will translate intricate gas dynamics—from free-molecular to continuous flow regimes—into dependable computational predictions that are integrated into our multi-physics design framework.
Key Responsibilities:
Model Development & Validation: Create and rigorously validate a high-fidelity CFD model of the fusion chamber that accurately reflects dominant gas dynamics, including reverberation and complex hybrid flow behavior, spanning from free-molecular to continuous.
Parametric Simulation & Analysis: Design and implement a systematic series of CFD simulations to investigate and optimize design parameters. Analyze the impact of chamber geometry, port configuration, gas type, and pressure on the resulting flow fields.
Integrated System Design: Collaborate effectively with mechanical, thermal, and target injection teams to integrate CFD results into the broader reactor design framework. This includes:
Coupling CFD-derived flow fields and thermal loads with thermo-mechanical solvers to evaluate first wall survivability.
Integrating CFD results with target injection models to assess the aerodynamic stability of the fusion capsule during flight.
Digital Engineering & Tools: Develop robust meshing tools, High-Performance Computing (HPC) workflows, and visualization tools to ensure that CFD simulations are scalable, efficient, and reproducible within our expansive research and development environment. Define necessary model improvements and validation activities to continuously mitigate risks associated with reactor gas dynamics and thermal management designs.
External Collaboration Management: Actively manage and foster external research collaborations with universities and national laboratories to enhance our CFD capabilities.
