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 …

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

The unsteady flowfields generated by convoluted aeroengine intakes are sources of
instabilities that can compromise the performance of the downstream turbomachinery …

The next generation of turbofan aero-engines are likely to have an increase in fan diameter
to reduce the specific thrust and increase the overall propulsive efficiency. More compact …

A modification of a low speed preconditioning formulation is proposed to perform robust
computations for both internal and external flows. This formulation is based on the isentropic …

ABSTRACT The Propulsion Test Facility of the TU Braunschweig is capable of investigating
future jet engine intakes and fan aerodynamics to a high level of detail. A goal of this facility …

Flow separation under crosswind conditions seriously jeopardizes the quality of the
nacelle's flow field. In this paper, microsecond pulsed surface dielectric barrier discharge …

This paper studies the computational modelling of the flow separation over the engine
nacelle lips under the off-design condition of significant crosswind. A numerical framework is …

THE modern civil aeroengine intake is expected to provide the fan with a steady, uniformly
distributed flow in a wide variety of operating conditions. This poses a problem to designers …

N the current airframe design context, every component is expected to be always better
performing from one generation to the next. In particular, engines are required to reach …
