Merger of three parallel pipe flows (same speed) at low Reynolds number

Merger of three parallel pipe flows into a channel at low Reynolds number. The inflows through the inlets have the same parabolic profile. The resulting flow is symmetrical and steady in time. This simulation has to be compared with the similar ones in the Album, including higher Reynolds number and different types of inflows.

  Visualization via tracing of concentration, starting from the inlet, shaded (first, 0.6 MB) and via isolines (second, 1.6 MB). The color red means `value of concentration +1' while blue stands for 'value of concentration -1'. Consequently, the green regions represent the mixed zones!
