A configuration of the water tunnel with two independently controlled concurrent streams is presented. Two important zones of the flow, namely: an inner layer with even parameter profiles and a mixing layer between two streams, can be observed. The numerical simulation results obtained by means of the CFX-TASC flow code are compared with the experimental investigation results measured by a Pitot probe in the velocity range from 1.7 to 16 m/s.
