Computational fluid dynamics (CFD) plays an essential role to analyze fluid flows and heat
transfer situations by using numerical methods. Turbomachines involve internal and external …

The performance of a transonic fan operating within nonuniform inlet flow remains a key
concern for the design and operability of a turbofan engine. This paper applies …

Boundary Layer Ingesting (BLI) turbofan engines could offer reduced fuel burn compared
with podded engines, but the fan stage must be designed to run continuously with severe …

This paper describes a collaborative CFD development framework led by Rolls-Royce plc.
The framework is novel both in the underpinning CFD solver and the network of CFD …

Integration of sensors into various kinds of products and machines provides access to in-
depth usage information as basis for product optimization. Presently, this large potential for …

Casing grooves are known to increase the stable operating range of axial compressors. The
mechanism by which this stability enhancement occurs is poorly understood. This paper …

Swirling flows are now widely being used in modern gas turbine combustors to improve the
combustion characteristics, flame stability, and reduce emissions. Residual swirl at the …

The use of optimization methods to design aerodynamic sections is now completely routine
in many companies and research institutes; see [1] for an introduction to this approach …

Prior to the detailed design of components, turbomachinery engineers must guide a mean-
line or throughflow design toward an optimum configuration. This process requires a …

This paper considers the effect of small variations in leading edge geometry, leading edge
roughness, leading edge fillet, and blade fillet geometry on the three-dimensional …
