The purpose of this study is to clarify the structure of pseudo-shock waves in under-expanded jet issuing from asymmetric nozzle with an oblique outlet. In particular, the steady characteristics of a single jet flow were studied. The flow was visualized by the shadowgraph method and the mean pitot pressures were measured. It was clarified that the asymmetric under-expanded jet was deflected by the stagnation pressure. As a result, it was found that the structure of pseudo-shock wave was affected considerably by the stagnation pressure in an air chamber and the outlet angle of nozzle, and consequently the structure of the pseudo-shock waves were different from the axisymmetric under-expanded jet.
