An Experimental Study on an Underexpanded Annular Impinging Jet

概要

• 論文の詳細を見る

• An underexpanded annular impinging jet is studied experimentally and it is shown that the aerodynamic characteristics of the impinging jet depend significantly on the distance H between the nozzle exit plane and the impinged flat plate. The annular impinging jet diverges in the downstream direction provided H is smaller than a critical value H_C. The feature of the jet changes significantly at H=H_c. The stream lines issuing from the inner edge of the annular nozzle join at a point upstream of the impinged plate. However, a vortex ring may appear on the plate even for H>H_c depending on the magnitude of loss in the stagnation pressure at the jet axis.
