Reynolds-averaged Navier–Stokes modelling in transonic S-ducts with passive flow control (2020)
Journal Article
Hickling, T., & Ingram, G. (2020). Reynolds-averaged Navier–Stokes modelling in transonic S-ducts with passive flow control. Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 234(1), 31-45. https://doi.org/10.1177/0957650919845765

S-duct diffusers are used in aircraft with embedded engines to route ambient air to the fan face. Sizing and stealth considerations drive a need for high curvature ducts, but the curvature causes complex secondary flows that lead to total pressure di...
