The Digest’s Multi-Slide Guide to Multi-Phase Flow Studies of SAFs

This $550k (exp) + $175k (sim) FY24 project, running until 2027, focuses on X-ray diagnostics and high-fidelity CFD for SAF internal flow and atomization. Critical insights into as-built nozzle geometry (25 µm foreign object, micron-scale helical grooves) influencing spray morphology have been revealed. New window designs validate >150 bar performance for high-pressure experiments. A GPU-accelerated Real Fluid Model (MeGS-RFM) improves accuracy for SAF thermophysical properties, with all data openly available online.
