Abstract

A prominent industrial application of confined vortex flow is the gas cyclone separator. In the vortex core, the flow is dominated by coherent low frequency oscillations, which have also been observed in vortex breakdown cases [1, 2]. This precession of the vortex core (PVC) tends to affect velocity measurements obtained with experimental one-point techniques like laser-Doppler anemometry (LDA) and contributes to the measured Reynolds stresses as pseudo-turbulence. In this way, a proper evaluation of the performance of Reynolds stress transport models is complicated.
