Search for: [Abstract = "Flow\-visualization motion pictures of side, top and span views in a plane confined mixing layer were obtained. The formation of vortical coherent structures and their further evolution were observed and filmed for several values of the characteristic parameters lambda = U2\/U1 and Delta\(U\) = U1\-U2. The influence of these two parameters on the appearance of the vortices and their subsequent evolution was investigated. A statistical analysis of digitized flow pictures has made it possible to determine the mean position of the birth of the vortices and to follow their evolution thoroughly."]
