CFD Engineer Intern

Company : Signet Arms

Location : Remote (India)

Type : Paid Internship (Full Time)

Duration : 3–6 months (with potential extension)

Company Description

Signet Arms is an innovative defense technology company. We are building next-generation agentic AI systems, enabling autonomous reasoning, workflow orchestration, and intelligent automation. Our work combines LLM engineering, applied ML, and modern AI toolchains to push the boundaries of engineering automation.

Role Description

We are seeking a highly motivated CFD Engineer Intern to support high-fidelity aerodynamic simulations and analysis. You will work closely with our engineering team to set up, run, and validate CFD cases involving external aerodynamics of wings, airfoils, and aircraft configurations. The role involves mesh generation, solver setup, post-processing, and extracting key aerodynamic quantities to support ongoing R&D projects.

Responsibilities

• Perform CFD simulations using OpenFOAM for external aerodynamic applications (airfoils, wings, aircraft geometries).
• Generate structured and unstructured meshes using blockMesh and snappyHexMesh.
• Set up incompressible and compressible flow solvers, boundary conditions, and turbulence models.
• Conduct mesh independence studies, simulation validation, and result verification.
• Extract and analyze aerodynamic performance metrics such as lift coefficient (CL), drag coefficient (CD), pressure distributions, and flow visualization.
• Post-process results using ParaView or similar tools.
• Collaborate with engineering teams to design, optimize, and evaluate aerodynamic concepts.
• Document simulations, results, and workflow methodologies.
