Flow visualization, as a part of experimental fluid mechanics, is a typical initial step of many experimental studies. It can contribute significantly to the understanding of mechanisms involved in flow fields. Moreover, it can be helpful in the selection of the flow parameters and regions of interest for local and detail point measurements. The visualization can be very beneficial for a precise adjustment of a chosen flow field pattern in a test section if alternative flow field modes are possible. Typical case is a bistable and hysteretic behavior of complex flows. The paper shows a few cases of complex jet and wake flows, namely impinging jets from standard and special nozzles (round and slot nozzles, annular nozzle with a fluidic or acoustic control, two-slot nozzle, and slot nozzle with the Coanda effect), and a non-isothermal wake flow behind a cylinder in the cross flow.
