The design process of a gas turbine engine involves interrelated multi-disciplinary and multi-
fidelity designs of engine components. Traditional component-based design process is not …

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 …

Abstract Unsteady Reynolds-averaged Navier–Stokes modeling (URANS) is a valuable and
cost-effective tool for computational fluid dynamics (CFD), including the investigation of …

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 …

Ultra high by-pass ratio (UHBR) turbofan configurations are promising concepts to address
the issue of aircraft fuel burn reduction. The large fan diameter and the small ground …

This article demonstrates the utility and implementation of software prefetching in an
unstructured finite volume computational fluid dynamics code of representative size and …

Computational fluid dynamics (CFD) has been widely adopted in the compressor design
process, but it remains a challenge to predict the flow details, performance, and stage …

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 …

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 …
