Abstract
To make clear the flow behavior of a turbulent jet, the authors have applied the Schlieren method to the two-dimensional jet impinging obliquely on a solid wall. For flow visualization, the central parts of the two-heating the flowing air itself to eliminate the end effects of plane jet, e.g. the entrainment effect of ambient air or the boundary effect on side wall.
In the present paper, some photographic results of jet flow pattern are compared with each other, and the effects of the initial jet velocity (u0), the distance(H) between nozzle and wall and the impinging jet angle (θ) on the behavior of impinging jet are discussed.
