The present study examines the near-field flow developments and dynamics of parallel twin
jets in cross-flow (TJICF) configured with jet-to-jet separation distances of 1.5 to 3 jet
diameters (D) and velocity ratios of 2, 4, and 6. Both laser-induced fluorescence and particle-
image velocimetry measurements were made along the streamwise and cross-stream
planes in order to investigate the effects of the separation distance and velocity ratio upon
the deflected jet and the formation of counterrotating vortex-pairs (CVPs) within the near …
