The flow fields of the jets into counterflowing uniform flow include regions of large diffusion. Investigating of the flow field is important to know the diffusion phenomenon. And the results are useful to discuss the fields of combustion, mixing, and so on. Recently we found that there is mixing layer structure and no re-circulating zone. In this paper, this flow field is divided into three groups, flattering, puffing and attached flow, depend on the vortex pattern. The field is investigated by the measurements of the velocity, static pressure, and visualization.
