OVERVIEW

Objective Simulate and analyze viscous–turbulent flow through a contraction–test section–diffuser wind tunnel at multiple inlet velocities. Engineering Work Created 2D CFD models using air as an ideal gas with Sutherland viscosity Simulated inlet velocities of 10 m/s and 25 m/s Generated contours of static, dynamic, and total pressure, velocity, and streamlines Extracted centerline and vertical profiles for quantitative comparison Bonus Aerodynamics Study Modeled a 2D circular cylinder in the test section Computed pressure coefficient (Cp) distributions Extracted drag and lift forces and calculated Cd and C

Aerospace Engineer | Propulsion, Aerodynamics & Structural Analysis

Aerospace engineer with strong analytical and simulation-driven experience across propulsion systems, high-speed compressible flow, aerodynamics, CFD, and structural fracture mechanics. Demonstrated ability to translate theory into validated engineering insight through system-level design projects, numerical simulations, and parametric studies. Experienced with MATLAB, ANSYS Fluent, Abaqus, Python automation, and aerodynamic analysis tools. Seeking entry-level or associate aerospace engineering roles in propulsion, structures, aerodynamics, or systems engineering.


I’m currently seeking full-time opportunities in aerospace propulsion, systems engineering, or R&D, where I can contribute to mission-driven projects and continue growing as an engineer.


Long-term, I aim to contribute to technologies that enable deep space exploration, especially sustainable missions to Mars. Whether through propulsion, entry systems, or autonomous spacecraft, I want to help shape the future of interplanetary travel through grounded engineering and innovation.
