This type of flow is dominated by the presence of many complex vortices that come from the recombining of the vorticity created in the injection tube and that create along the chamber floor. Results indicate in particular that the organization of the line of vortices, created on the boundary of the jet, depends on the existence of a focus located near the injection hole. Conditions of appearance of this instability have been specified, then a quantitative study of its main characteristics has been conducted by statistical analysis of video recordings. %8 1996-09-01
