This paper presents a review of proper orthogonal decomposition (POD) methods for order
reduction in a variety of research areas. The historical development and basic mathematical …

Inlet flow distortion is expected to play a major role in future aircraft architectures where
complex air induction systems are required to couple the engine with the airframe. The …

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 …

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 …

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

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 …

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

For some embedded engine arrangements, the nature of the inlet distortion is influenced by
the boundary layer characteristics at the inlet plane of the intake. This research presents the …

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 …

Peak events of unsteady total pressure and swirl distortion generated within S-duct intakes
can affect the engine stability, even when within acceptable mean distortion levels. Even …
