Thermal - Fluids Analysis Engineer
About The Position
As an analyst at Antares your primary responsibility will be building and running thermal-fluids models of components and subsystems throughout the reactor core and power conversion system to ensure our designs will meet thermal, mechanical, operational, and performance requirements within the extreme environments of our R1 micro-reactor. Design engineers will rely on your modeling and technical expertise for iterative design feedback and optimization, while adhering to best practices for DFM (design for manufacturing) and maintaining a rapid pace of development. Antares aims to maintain close collaboration between testing and analysis teams, and to this end you may often be asked to provide technical support before, during, and after test campaigns. This may take the form of cooperative planning of testing goals, instrumentation requests, root cause analysis in the event of failures, post-test data review, and model validation/anchoring.
Requirements
- Bachelor's in Mechanical or Aerospace Engineering or similar technical discipline
- 3+ years experience performing thermal-fluids analysis
- Experience building and running CFD models using commercial codes such as Fluent, CFX, and Star-CCM+, including conjugate heat transfer models and compressible equations of state
- Experience using Computer Aided Design (CAD) software for design modification and model defeaturing (Siemens NX or similar)
- Experience in Python, MatLab, VBA, or other scripting language to build and maintain tools and calculators
Nice To Haves
- Master's in Mechanical or Aerospace Engineering or similar technical discipline
- 5+ years experience performing thermal-fluids analysis
- Familiarity with 1-D fluid network tools such as Flownex, Sinda-Fluint, or RELAP5
- Participation in regulatory qualification or certification programs for safety critical systems in the aerospace or nuclear industry
- Understanding and experience of implementing numerical methods to solve fluid-dynamic and thermodynamic systems
- Experience working with multiphase fluid & heat transport systems (Heat Pipes, Rankine Cycle Engines, Saturated Cryogenic Storage)
- Familiar with ASME BPVC Section III Div 5
- Experience building and running Finite Element Analysis (FEA) models
- Comfortable in fast-paced environment with rapid design iteration loops
Responsibilities
- Assess subcomponent designs for pressure drop, heat transfer capabilities, and other performance characteristics using a combination of hand-calcs, in-house tools, and CFD
- Collaborate with designers and responsible engineers to provide guidance on initial sizing, material selection, and design feedback based on analytical results
- Compile detailed documentation of analytical results and communicate key results, assumptions, and limitations to stakeholders throughout the company and external customers
- Provide support to test engineers in the form of collaborative test design, instrumentation selection, and data review to ensure test campaigns provide the necessary data to validate our models
- Develop internal tools and calculators to enable other engineers to quickly and independently perform analytical assessments of their designs without the need for detailed finite element models
- Provide technical mentorship and guidance to other engineers and across teams
