Jet flow in a box at medium Reynolds number (II)

Jet flow into a box with additional slow inflow from the left edge. The outflow is in the right part of the lower edge. For this medium up to large Reynolds number, the resulting flow gets completely nonsteady, with very complex dynamics in space and time. This simulation has to be compared with the similar `Jet flow into a box' configurations in the Album, including lower Reynolds numbers and different types of in- and outflows.

• Distribution of temperature/concentration via Boussinesq model
  
  

  Visualization via tracing of concentration, starting from both inlets ("slow" left edge and a "fast" small upper inlet) in the left column (2.8 MB). Here, the color red means `value of concentration +1' while blue stands for 'size of concentration -1'. Consequently, the green regions represent the mixed zones (concentration almost 0!). In the second column, we only visualize the flow coming from the small upper inlet (3.1 MB). Then, color blue indicates the regions where the concentration is 0!
