Selective laser melting (SLM) is widely used in making three-dimensional functional parts
layer by layer. Temperature magnitude and history during SLM directly determine the molten …

In this paper, we present the evaluation of the aerodynamic robustness to rim seal purge
flow of an optimized 1.5-stage axial turbine configuration with a bowed stator profile and …

An optimization has been performed on a well-proven radial compressor design known as
the SRV4 impeller (the Krain impeller), which has been extensively tested in the past, using …

The present study demonstrates the aerodynamic and acoustic optimization potential of a
counter rotating open rotor. The objective was to maximize the propeller efficiency at top of …

Within the frame of the ongoing 7th Framework European Project DREAM, this article
presents a synthesis of Cenaero, DLR, and Onera's joint effort to demonstrate the …

A new approach for modelling the roughness induced transition has been developed, which
is based on local variables and a transport equation. Thus information of flow history relative …

The distinguishing features of transition in turbomachinery flows are that they are unsteady
on time scales longer than typical eddy turnover times, occur in harsh and highly disturbed …

Zusammenfassung Titel: Modellierung des Grenzschichtumschlags bei

An approach for modelling the roughness-induced laminar–turbulent transition has been
developed, which is based on the γ–Reθ transition model by Langtry and Menter [1]. That …

An empirical riblet model for manufactured V-shaped and trapezoidal riblets which is
suitable for turbomachinery application is presented. The implementation of the riblet effect …
