Considerable progress in development and application of computational fluid dynamics
(CFD) for aeroengine internal flow systems has been made in recent years. CFD is regularly …

This paper describes the work done to achieve high parallel performance for an
unstructured, unsteady turbomachinery computational fluid dynamics (CFD) code. The aim …

To improve the quality of a manufactured part in industry, a variety of techniques are used to
scan a built geometry to bring it back to the physics based simulation world to assess its true …

The fan systems of typical high bypass civil engines encounter strong flow distortions
originating in the intake and the bypass duct. These flow distortions cause the fan stage …

The paper reports an experimental investigation into the possibility of increased interactions
between combustor external aerodynamics and upstream components, eg, prediffuser …

Experimental, computational fluid dynamics (CFD), and duct-acoustics theoretical studies
were conducted to investigate the mechanism of upstream noise propagation from fan …

The cyclic pattern design of fan outlet guide vanes (OGVs) is key to achieving the fan stage
performance and to set the aeromechanical behaviour of low-pressure compressor (LPC) …

This research proposes and preliminarily analyzes a novel concept to passively reduce the
negative impact of deep inlet distortion on the fan of an aero-engine. It consists of placing a …

The propulsive efficiency of civil aviation power plants can be effectively improved by
increasing the bypass ratio. Higher bypass ratios, however, exacerbate issues of …

The level of efficiency of modern turbines means that traditional blade design methods,
based on steady state CFD in an idealised annulus, are no longer able to yield the efficiency …
