There are numerous unsteady flow influences in turbomachinery. These can potentially
make a substantial total impact on efficiency, and hence the environment and operating …

General forms of turbulence models are outlined along with their defects and palliatives for
these in relation to turbomachinery. The turbulence modelling hierarchy available in …

This paper presents a low-order model applying the immersed boundary method on
smeared geometry. It is thus able to represent the effect of turbomachinery within a complex …

Abstract Das Ziel der vorliegenden Arbeit besteht darin, einen Beitrag zur Bewertung des
Triebwerksschalls bei Flugzeugkonfigurationen mit stark in den Rumpf integrierten …

The use of boundary-layer-ingesting, embedded propulsion systems can result in inlet flow
distortions where the interaction of the boundary-layer vorticity and the inlet lip causes …

With the advent of high bypass ratio turbofan engines of increasing size, new nacelle
designs with shorter air intakes have to be considered, creating new aerodynamic …

Very high bypass ratio turbofans with large fan tip diameter are an effective way of improving
the propulsive efficiency of civil aero-engines. Such engines, however, require larger and …

One of the major challenges in high-speed fan stages used in compact, embedded
propulsion systems is inlet distortion noise. A body-force-based approach for the prediction …

Abstract The Immersed Boundary Method has been used to simulate a range of fundamental
flows and turbulence. Such studies have demonstrated the method's promising applicability …

Modern trend in installation design is moving towards very high-bypass ratio turbofans. Very
high-bypass turbofans represent an effective way of improving the propulsive efficiency of …
