The study is a step in the development of a new method of investigation of aerosol formation out of gaseous precursors. The visualization was made in air, the numerical simulation used software FLUENT. The study focused on laminar flows, and on the stability loss of the inner round jet. A series of flow patterns is presented and the result is comparable with a classification known from available literature. Certain differences in scenarios of the patterns were observed such as three-dimensional structures and helical modes. To portrayal these structures, a stereoscopic technique was employed. The passing frequency was evaluated stroboscopically.
