Competitive electricity prices and reduced profit margins have forced hydraulic turbines to
operate under critical conditions. The demand for extended operating ranges and the high …

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

Recent advances and challenges in the generation of reduced order aerodynamic models
using computational fluid dynamics are presented. The models reviewed are those that can …

In this paper, we briefly review the classical harmonic balance method, and describe the
adaptation of the method required for its application to computational fluid dynamics models …

Unsteady blade row interaction (UBRI) has a large impact on performance in high-speed
axial compressors. Thus, the influence of UBRI should be accurately predicted in …

Hydraulic turbines are widely used to meet real-time electricity demands. Computational
fluid dynamic (CFD) techniques have played an important role in the design and …

Applications of computational fluid dynamic (CFD) techniques to hydropower have
increased rapidly in the last three decades. The majority of the experimental investigations …

The air intake-compression systems of modern aircraft usually use the aero-engine intake
and fan/compressor as the main components. Inlet-engine compatibility has always been …

The high pressure (HP) turbine is subject to inlet flow nonuniformities resulting from the
combustor. A lean-burn combustor tends to combine temperature variations with strong swirl …
