Interaction between a detonation and the Prandtl-Meyer expansion is an interesting problem in connection with disappearance or continuance of the fish-scale pattern. In this study, seven kinds of reflection nozzles were utilized in order to produce the Prandtl-Meyer expansion effects at various levels. Stability and behavior of detonation propagating in a reflection nozzle incorporating with a parallel channel part were experimentally observed with the initial pressure as a parameter using optical measurement methods such as open-shutter and schlieren photographic techniques. It was found that in the case of a nozzle at the half-vertical angle of A=18 degrees without the throat length, an initial pressure of at least 5.3 kPa is needed for sustentation of detonation configuration during passage through this nozzle.
