This paper is a review of significant studies in the complex flow physics in diffusive, s-
shaped ducts, focusing on flow control methods employed to counteract the onset of …

For many embedded engine systems, the intake duct geometry introduces flow distortion
and unsteadiness, which must be understood when designing the turbomachinery …

The unsteady distorted flow fields generated within convoluted intakes can have a
detrimental effect on the stability of an aero-engine. The frequency signature in the distorted …

The unsteady flowfields generated by convoluted aeroengine intakes are sources of
instabilities that can compromise the performance of the downstream turbomachinery …

Convoluted aero-engine intakes are often required to enable closer integration between
engine and airframe. Although the majority of previous research focused on the distortion of …

Some types of aero-engine intake systems are susceptible to the generation of secondary
flows with high levels of total pressure fluctuations. The resulting peak distortion events may …

An experimental study was conducted on the flow control capability of sweeping jet
actuators (SJAs) in an aggressive offset S-shaped duct with an inlet Mach number of 0.4 …

The unsteady distorted flowfields generated within convoluted aeroengine intakes can
compromise the engine performance and operability. Therefore, there is a need for a better …

Curvature change of an S-duct wall naturally causes total pressure and swirl distortions in a
compressor inlet. In this study, the large eddy simulation (LES) method is used to investigate …

The dynamic flow distortion generated within convoluted aeroengine intakes can affect the
performance and operability of the engine. There is a need for a better understanding of the …
