Aircraft noise remains the key inhibitor of the growth of air transportation, but the focus of the
noise mitigation strategies has changed. As the propulsor fan pressure ratio is decreased for …

Purpose The purpose of this paper is to explore a methodology that allows to represent
turbomachinery rotating parts by replacing the blades with a body force field. The objective …

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 …

Rotating stall is a natural limit to the stable operating range of compressors due to the
inverse pressure gradient of viscous gas. Effective prediction of compressor stall boundary is …

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 …

Boundary layer ingestion (BLI) fans are required to continuously operate under distorted
inflow conditions, which severely reduces the fan's efficiency. Therefore, it is necessary to …

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 …

To investigate the aerodynamic characteristics of the fan in windmilling conditions, a new
body force model with the fan rotational speed prediction model was developed. The fan …

The primary focus of modern civil jet engine intake design is to enhance propulsive
efficiency through an increase in the bypass ratio of the turbofan engine, which requires an …

With the rise of ultra high bypass ratio turbofan and shorter and slimmer inlet geometries
compared to classical architectures, designers face new challenges as nacelle and fan …
