Table 2 Reynolds numbers re in the Y-channel and Z-channel at specific cross section displayed in Fig. 2e and j, respectively. The Reynolds numbers are given as arithmetic mean based on the volume flow with its standard deviation; volume flows were measured via the duration of the outlet flow in n = 3 independent measurements. Reynolds numbers in bold indicate transition ranges from laminar to turbulent flow in the respective channel section.
