What is it about?
Flow through a S-Duct diffuser is simulated using a general purpose CFD code ANSYS Fluent. Mesh independence studies, turbulence model sensitivity and modeling effects of the AIP rake and flow control devices have been conducted with success.

Why is it important?
ω-based Reynolds Stress Model (RSM) and k-ω SST were used to capture the complex flow features inside compact S-duct diffuser.
