This paper reviews the development of computational fluid dynamics (CFD) specifically for turbomachinery simulations and with a particular focus on application to problems with complex geometry. The review is structured by considering this development as a series of paradigm shifts, followed by asymptotes. The original S1-S2 blade-blade-throughflow model is briefly described, followed by the de...

With increasing design demands of turbomachinery, stochastic flutter behavior has become more prominent and even appears a hazard to reliability safety. Stochastic assessment is an effective measure quantify the failure risk improve aeroelastic stability. However, for complex turbomachinery with multiple dynamic influencing factors (i.e., aeroengine compressor time-variant loads), hard be achie...

The purpose of this work is to compare di erent low-Reynolds-number turbulence models and their suitability for the highly three dimensional return channel with a deswirl cascade. A comparison is made between Chien's k model, Chien's model with a rotational correction, Gatski et al. ARSM and the full Reynolds stress model by Speziale et al.. Experiments are provided by Concepts ETI. MAIN RESULT...

Abstract We note that Eq. (7) in the original paper is wrong, namely, it contains turbomachinery diameter, D, at denominator instead of numerator
