An experimental investigation of the interaction and merging of two turbulent line vortices is described. The vortices were generated by two airfoils set at opposite angles of attack, and they were of opposite sign and equal strength. As the vortices proceed downstream they rotate around each other, and eventually they merge to produce a dominant, central vortex, with vestigal traces of the original vortices. Mean flow and turbulence measurements were made throughout the merging zone. The circulation profiles varied logarithmically with radius, for a considerable radial extent, at all stations.
