The choice of turbulence model can have a strong impact on results for many
turbomachinery zones. Palliative corrections to them and also transition modeling can have …

Distributed propulsion is one of the revolutionary candidates for future aircraft propulsion. In
this journal article, the potential role of distributed propulsion technology in future aviation is …

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 …

An experimental investigation has been carried out to determine the aerodynamic
performance of an annular S-Shaped duct representative of that used to connect the …

This paper considers the effect of an upstream compressor stage on a compressor inter-
spool duct. The duct geometry must be fixed early in the engine design process, well before …

Interturbine diffusers offer the potential advantage of reducing the flow coefficient in the
following stages, leading to increased efficiency. The flows associated with these ducts differ …

This paper presents a new design methodology for strutted S-shaped compressor ducts that
allows for more aggressive designs while maintaining current levels of duct loss. A baseline …

Interturbine diffusers provide continuity between HP and LP turbines while diffusing the flow
upstream of the LP turbine. Increasing the mean turbine diameter offers the potential …

Within gas turbines the ability to design shorter aggressive S-shaped ducts is advantageous
from a performance and weight saving perspective. However, current design philosophies …

The compressor inter-spool duct (ISD), with its offset and profiled curvature, is an inherent
part of the turbofan system due to large density gradients and substantial area changes …
