“…Isentropic flow is assumed from the reservoir to the nozzle inlet. Experimental data are taken from [45], where Schlieren images of the external flowfield and total pressure measurements along the axis of symmetry are presented. In the computations, geometry 1.5C of [45] has been considered, see Fig.…”

“…For a pressure at the nozzle exit higher or lower than the back pressure, the supersonic jet can be termed as ''under-expansion'' or ''over-expansion'', respectively. The pressure at the correct expansion state is exactly matched with the back pressure (Mitchell et al 2012;Katanoda et al 2000). However, the same pressure ratio is not applicable to specify the supersonic jet produced by the primary motive nozzle in an ejector-diffuser system.…”

“…The jet structure has been known as a fundamental phenomenon of the supersonic fluid mechanics. This type of jet is very important for some industrial devices [1,2]. Teshima [3] has suggested the possibility of occurring hysteresis in the supersonic jet formed by the rectangular orifice.…”

In recent studies on two-dimensional supersonic jets, it is reported that the hysteresis phenomenon for the reflection type of shock waves in the jet flow field is occurred under the quasi-steady flow condition and this phenomenon is affected by the transitional pressure ratio between the regular reflection and Mach reflection. However, so far, there are few researches on the hysteresis phenomenon for the transition of shock waves between regular and Mach reflection in over-expanded supersonic jets and the phenomenon has not been investigated satisfactorily. Therefore, the purpose of this study is to clarify the hysteresis phenomena for the reflection type of shock wave in the over-expanded axi-symmetric supersonic jet experimentally, and to discuss the relationship between hysteresis phenomenon and rate of the change of pressure ratio with time. Furthermore, the effect of Mach number at the nozzle exit on hysteresis loop was investigated for two kinds of nozzle.
