Internship Cfd Modeling information

What is an internship in CFD modeling?

An Internship in CFD (Computational Fluid Dynamics) Modeling is a temporary position, typically for students or recent graduates, where individuals gain practical experience in simulating fluid flows using specialized software. Interns work on projects that involve setting up and running CFD models, analyzing results, and assisting with research or engineering tasks. This hands-on experience helps interns develop skills in mathematics, physics, computer programming, and engineering applications, preparing them for future roles in industries such as aerospace, automotive, and energy. Interns often work under the supervision of experienced engineers or researchers.

What types of projects and responsibilities can I expect as an intern in CFD modeling?

As a CFD modeling intern, you’ll typically work on projects involving the simulation and analysis of fluid flows, often supporting senior engineers with tasks such as setting up simulation models, running computational analyses, and interpreting results. You may be involved in validating simulation data, optimizing designs, or preparing reports and presentations for team meetings. Collaboration with other engineering teams—such as mechanical or aerospace engineers—is common, and you’ll likely use industry-standard software like ANSYS Fluent or OpenFOAM. This hands-on experience helps build practical skills and can provide a foundation for future roles in engineering analysis or simulation.

What are the key skills and qualifications needed to thrive as an internship in CFD modeling?

To thrive as an intern in CFD Modeling, you need a solid understanding of fluid dynamics, thermodynamics, and numerical methods, typically supported by coursework in engineering or applied sciences. Familiarity with CFD software such as ANSYS Fluent, OpenFOAM, or COMSOL Multiphysics, and basic programming skills in languages like Python or MATLAB, are highly valued. Strong analytical thinking, attention to detail, and effective communication help interns interpret simulation results and collaborate with engineering teams. These skills ensure accurate simulations, valuable insights for project teams, and successful integration into real-world engineering workflows.

What is the difference between Internship Cfd Modeling vs Internship Fluid Dynamics?

AspectInternship Cfd ModelingInternship Fluid Dynamics
Required SkillsComputational Fluid Dynamics (CFD), simulation software, programmingFluid mechanics, experimental methods, data analysis
Work EnvironmentSoftware-focused, engineering firms, research labsLaboratories, research centers, industrial settings
Industry UsageDesign optimization, aerodynamics, thermal analysisFlow behavior studies, experimental validation

Internship Cfd Modeling focuses on developing and applying computational simulations to analyze fluid flow, while Internship Fluid Dynamics emphasizes experimental and theoretical study of fluid behavior. Both roles require a background in engineering or physics and are common in research and industry settings. The main difference lies in the approach: CFD modeling is software-driven, whereas fluid dynamics internships often involve hands-on experiments.

Job description

About the Team

The Thermal Engineering team enables Anduril's rapid hardware development cycle by ensuring advanced defense systems perform reliably in demanding real-world environments. The team works across high-power, tightly integrated products where thermal architecture, analysis, testing, and cross-functional design decisions directly affect product performance, reliability, and mission success.

About the Role

We are looking for a Thermal Design Engineer to join our team in Costa Mesa, CA. In this role, you will support thermal design and analysis for advanced defense hardware across drones, aircraft, missiles, and related flight systems.

This role is ideal for someone early in their career with strong heat transfer and fluid dynamics fundamentals from graduate coursework or research, who wants to grow into full ownership of thermal design problems in a fast-paced environment.

What You'll Do

  • Support thermal design and analysis for integrated hardware products, including drones, aircraft, missiles, or related defense systems
  • Apply first-principles engineering judgment using hand calculations, spreadsheets, and MATLAB/Python models to inform design decisions
  • Build and maintain thermal FEA/CFD models to predict system performance and establish design limits
  • Support prototype builds and thermal tests, including sensor selection, DAQ setup, data post-processing, and results documentation
  • Contribute to defining thermal architectures for rugged environments, demanding flight envelopes, and mission-specific thermal conditions
  • Partner with electrical, mechanical, aerospace, and systems engineers to document power dissipation, operating modes, and thermal constraints
  • Present thermal analysis results and recommendations in internal design reviews
  • Develop internal tools, workflows, or analysis methods that improve speed and quality of thermal decision-making

Required Qualifications

  • MS in Mechanical Engineering, Aerospace Engineering, Applied Physics, or a related field with a focus on heat transfer, fluid dynamics, thermal sciences, or thermal systems
  • Strong first-principles understanding of heat transfer and fluid dynamics, including conduction, convection, radiation, fluid flow, and transient thermal behavior
  • Coursework, research, or internship experience in thermal analysis, modeling, or testing
  • Experience with MATLAB, Python, or similar tools for engineering analysis
  • Ability to communicate technical concepts clearly to cross-functional teams
  • Ability to obtain and maintain a U.S. Top Secret security clearance

Preferred Qualifications

  • 1-3 years of industry experience in thermal engineering for aerospace, defense, or high-performance hardware systems
  • Experience with thermal analysis tools such as STAR-CCM+, ANSYS, Icepak, Flotherm, or comparable FEA/CFD platforms
  • Experience with CAD tools such as SolidWorks or Siemens NX
  • Graduate research in thermal-fluid systems, electronics cooling, aerothermal analysis, or related areas
  • Exposure to thermal testing, including instrumentation, data acquisition, and test-to-model correlation
  • Strong motivation to support Anduril's mission of defending the United States and allied partners
