AB Proper Orthogonal Decomposition (POD) has been used broadly in analyzing turbulent flows at high Reynolds numbers, such as flow in apipe. However, there exists a lack of knowledge in analyzing some other regimes which contain interesting temporal behaviors. We presenttwo study cases with completely different flow regimes showing the advantages of analyzing them using POD. First, we describe anapplication in creeping flow (very low Reynolds number) in Non-Newtonian fluids. POD helps characterize the different bifurcations of theflow directly related to the movement of stagnation points of the problem. We have also proved the efficiency of this method to store datarecovering 90% of the temporal evolution with only a few geometric modes (time-independent) and some temporal modes, which are asingle value for each time. Second, we analyze experimental data of a wing tip vortex at moderate Reynolds numbers. The possibleattenuation of this kind of vortices is a key criterion for any airport design. By using POD, we were able to describe the vortex and isolate amode representing the global attenuation of the vortex.
