Numerical study of the instabilities of swirling jets

På svenska

Author

Summary, in English

The stability of circular swirling jets is studied numerically in order to evaluate the influence of Reynolds number in the laminar regime, swirl level and inlet geometrical perturbations on the appearance and evolution of axial and asymmetric modes. The results reveal increasing deviation from symmetry with increasing Reynolds numbers and swirl levels. The critical value of the Reynolds number corresponding to the appearance of an asymmetric mode is also determined. Geometric perturbations are found to affect the dominant asymmetric instability mode.
