| Abstract: | The velocity ratio of a free shear layer has an important influence on the spatial developments of large scale coherent structures in the layer. In this study, numerical simulations are performed to get an insight into this problem. The obtained numerical results agree quite well with that of a linear inviscid stability theory and the available experimental data. |
