• Built and analyzed 1-D hydraulic models of water distribution networks for steady-state and transient operation using Allievi • Conducted surge and water hammer studies, including pump shutdowns and valve closures • Identified risks of cavitation and overpressure, and implemented design mitigations to guarantee reliability and compliance with system safety requirements • Sized piping for water management installations and reviewed P&IDs for design integration

• Conducted FSI simulations of sloshing for satellite mono-propellant fuel tanks with elastic diaphragms using OpenFOAM and solids4Foam • Developed and validated a drainage model of fuel tanks by performing FSI simulations to track diaphragm motion during emptying, comparing results against experimental measurements. • Analyzed CFD results of bi-propellant tank sloshing simulations to assess centre-of-mass variations

• Tested of a microjet engine prototype as part of a team, including engine mounting and test stand setup • Processed and analyzed experimental data to evaluate engine performance using Python • Performed preliminary thermodynamic cycle calculations for propulsion system using Python • Converted 3D CAD models into manufacturing-ready 2D technical drawings in CATIA V5

• Generated airfoil geometries using Matlab, based on NACA-series profiles, for aerodynamic evaluation • Built structured meshes using blocking techniques in ICEM CFD • Conducted aerodynamic performance estimation via Ansys Fluent simulations
