Experimental study on the flow field characteristics in the mixing region of twin jets
Twin jets flow, generated by two identical parallel axisymmetric nozzles, has been experimentally investigated. The dimensionless spacing ( B) between two nozzles were set at 1.89, 1.75 and 1.5. Measurements have been carried out at several free-stream velocities ranging from 10 m/s to 25 m/s or Rey...

| description | Twin jets flow, generated by two identical parallel axisymmetric nozzles, has been experimentally investigated. The dimensionless spacing (
B) between two nozzles were set at 1.89, 1.75 and 1.5. Measurements have been carried out at several free-stream velocities ranging from 10 m/s to 25 m/s or Reynolds numbers (based on the nozzle diameter of 44 mm) ranging from 3.33 × 10
4 to 8.33 × 10
4. The results show that the twin jets attract each other. With the increasing Reynolds number, the turbulence energy grows, which indicates that the twin jets attract acutely. The jet flow field and the merging process of two jets vary with
B. The width of the twin jets flow spreads linearly downstream and grows with
B. The merging between two jets occurs at the location closer to the nozzle exit for the cases with smaller spacing between nozzles and higher Reynolds number. |
