Computational fluid dynamics (CFD) has been widely used for compressor design, yet the
prediction of performance and stage matching for multistage, high-speed machines remains …

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 …

The design and analysis of the secondary air system (SAS) of gas turbine engine is a
complex and time-consuming process because of the complicated topology and iterative …

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

Turbomachinery blade passages are conventionally meshed by sweeping a mesh from a
reference stream surface to other stream surfaces along the blade span. This approach is …

Turbomachinery blade rows can have non-uniform geometries due to design intent,
manufacture errors or wear. When predictions are sought for the effect of such non …

The treatment of compressible flows subject to periodic disturbances of finite amplitude with
nonlinear harmonic (NLH) methods requires a careful choice of averaging procedures and …

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