Abstract:
The transitional flow over a swept, backward-facing step is analysed using empirical eigenmode decomposition in order to identify dominant flow structures. Databases of three-dimensional velocity fields were generated by direct numerical simulation for sweep angles α between 0° and 60°. The Reynolds number, based on the step height and the free stream component normal to the step, is kept constant at Re = U0H/ν = 3200. The eigenvalue spectra of the decompositions exhibit a similar decay for all...     »
