Since the 1930s ducted-wind-turbines have received considerable attention due to the
possibility of obtaining a significant increase in the extracted power compared to an open …

In computational fluid dynamics (CFD), it is possible to identify namely two uncertainties:
epistemic, related to the turbulence model, and aleatoric, representing the random-unknown …

This paper offers an analytical formulation of the two errors embodied in the momentum
theory. The first one originates from the use of the differential form of the axial momentum …

This work describes a computational study into lip stall in subsonic civil aircraft intakes and
its alleviation by action of the fan. Beyond a certain flow incidence, the lower lip of a civil …

The main role of the intake is to provide a sufficient mass flow to the engine face and a
sufficient flow homogeneity to the fan. Intake-fan interaction off design represents a critical …

A recently proposed modification to fully compressible schemes significantly improves the
resolution of low-Mach-number features, tackling the problem of excessive numerical …

The paper provides an evaluation of the errors embodied in the Axial Momentum Theory
(AMT) as applied to a uniformly loaded actuator disk model without wake rotation. Although …

Recent trends in design for civil intakes lead towards shorter diffuser sections, unorthodox
installations and more loaded lips. All these features increase the risk of lip stall in flight at …

Trailing edge blowing is used in a great variety of applications. In particular, high-pressure
turbines bleed about 3% of the engine core massflow through a rear slot of the inlet guide …

A laser beam propagating in air and passing through a point diffraction interferometer (PDI)
produces stable interferograms that can be used to extract wavefront data such as major …
