About the role
Key Responsibilities
- Perform aerodynamic simulations across subsonic, transonic,
supersonic, and hypersonic regimes using CFD tools (e.g., Ansys Fluent)
to evaluate external airframe and internal duct/propulsion flow
performance.
- Analyze complex flow phenomena such as shock formation, expansion
waves, separation, and Shockwave–Boundary Layer Interaction, ensuring
accurate prediction of pressure, temperature, and heat flux distributions.
- Set up and execute CFD models for external flows (wings, fuselage,
control surfaces) and internal flows (intakes, nozzles, ducts), applying
appropriate boundary conditions, compressibility effects, and gas
dynamic principles.
- Apply advanced turbulence models — RANS, LES, DES, or hybrid
methods — and justify their selection based on flow regime, Reynolds
number,and accuracy requirements.
- Generate high-quality meshes for complex geometries using structured,
unstructured, or hybrid approaches, ensuring proper near-wall
resolution (y⁺ control) and grid independence for reliable aerodynamic
predictions.
- Conduct 6DOF dynamic simulations using dynamic and overset meshes
to study vehicle motion, stability, and control behaviour during free-flight
or moving-bodyscenarios.
- Post-process and analyse CFD results, extracting aerodynamic
coefficients (Cl, Cd, Cm), flow visualization plots (Mach contours, Cp
distributions), and force/moment data for design evaluation and
optimization.
- Collaborate with multidisciplinary teams (structures, thermal, propulsion)
by providing aerodynamic loads, surface pressures, and heat flux data
for coupled simulations and integrated performance analysis.
- Automate workflows and data analysis using Python or scripting tools for
mesh generation, solver execution, and result processing to improve
efficiency and repeatability.
- Document and communicate findings through detailed technical reports,
validation studies, and design recommendations to support airframe,
propulsion, and system-level development efforts
