Guderley Reflection for Higher Mach Numbers in a Standard Shock Tube
To resolve the von Neumann paradox, Guderley (1947) proposed a four-wave structure, consisting of an expansion fan in addition to the three shock wave configuration . Despite intensive experimental work at the time, no evidence of this expansion fan was observed, therefore dismissing Guderley’s proposal. Experimental work conducted by Skews and Ashworth  with the use of a large-scale shock tube showed experimentally for the first time that Guderley’s proposal was, in fact, correct.
