We introduce a hybrid model for the evaluation of jet noise. The model uses the information from a solution of the Reynolds-averaged Navier{Stokes equations (RANS). It evaluates the jet-noise power spectral density (PSD) in the quiescent region outsi

We report on combined velocity and unsteady pressure measurements obtained on an radial compressor with vaneless diffuser and asymmetric volute. Time-resolved PIV recordings were acquired at 26 kHz both upstream of the impeller as well as within the

A single stage industrial centrifugal compressor including vaneless diffuser and a non-symmetric volute is investigated with regard to the development of flow instabilities and rotating stall. A deeper understanding of flow phenomena that might be a

Strahllärm hat beim Start eines Flugzeuges einen wesentlichen Anteil am entstehenden Fluglärm. Es ist daher nach wie vor von großem Interesse, die zugrunde liegenden Mechanismen der Schallentstehung zu untersuchen und zu verstehen. Dazu können sk

Simultaneous flow and acoustic measurements have been acquired for an aircraft, during ground operation. Measurements of velocity field data with stereoscopic particle image velocimetry (SPIV) on the engine-exhaust jet are correlated with the acousti
