Expertise in CFD and External & Internal Aero (Subsonic to Hypersonic Regime). The ideal candidate will have a deep understanding of gas dynamics and shock interactions, aerodynamics, and possess excellent problem solving skills to deliver high-quality simulations for various projects. Function as a solution specialist in the field of Computational Fluid Dynamics using simulation tools such as ANSYS FLUENT, Chemkin or Star CCM+, ANSYS CFX.

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 energetic 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
