Using power spectral analysis, we confirm in this work that the transition from any N-gon to (N+1)-gon pattern observed within a hollow-core vortex of shallow rotating flows occurs in two steps. The regime was quasi-periodic before the frequencies lock (synchronization). The ratios of locking frequencies were found to be equal to (N-1)/N. }, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {11}, number = {4}, year = {2017}, pages = {742 - 746}, ee = {https://publications.waset.org/pdf/10006754}, url = {https://publications.waset.org/vol/124}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 124, 2017}, }
