An underexpanded annular impinging jet is visualized using a Mach-Zehnder interferometer and is also simulated solving compressible Navier-Stokes equations. A turbulence model developed by Coakley is used in the present simulation. It is shown that the calculated density distribution in the jet agrees fairly well with the measured distribution. Both the visual observation and the simulation show that the characteristics of the underexpanded annular 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 the critical value H<SUB>c</SUB>. However, for H>H<SUB>c</SUB>, the stream lines issuing from the inner edge of the annular nozzle join at a point near the nozzle exit.
